Next-Gen Privacy: How AI Is Transforming Secure Browsing and VPN Techn …

As we move through 2025, artificial intelligence (AI) is fundamentally reshaping secure browsing and Virtual Private Network (VPN) technologies. The explosion of sophisticated cyber threats, sharpened by the capabilities of AI and quantum computing, is forcing rapid innovation in privacy protection, user trust, and online security infrastructure.

The Data Privacy Wakeup Call

AI-Related Privacy Breaches: According to Stanford’s 2025 AI Index Report, AI incidents increased by 56.4% in just one year, with 233 major cases documented in 2024—including data breaches, algorithmic failures, and misuse of personal data.

Consumer Trust: 70% of global consumers have little to no trust in companies to use AI responsibly. 57% view the use of AI in data collection as a major threat to privacy, and 81% expect their information will be used in ways they won’t approve of as AI adoption grows.

Corporate Realities: 40% of organizations experienced an AI-related privacy breach, yet fewer than two-thirds are actively implementing safeguards. In practice, only 37% of small enterprises have any plans to use AI for privacy—highlighting resource and governance barriers.

VPN Usage and Privacy Surge

Explosive Growth: In 2025, the global VPN market is projected to hit $77 billion, up from $44.6 billion a year ago, with more than 1.9 billion regular users worldwide—representing a 20% year-over-year increase and over one-third of all internet users.

Regional Differences: North America leads with 30% market growth, Asia-Pacific is expanding at a 16% annual pace, and VPN usage has become routine in places like Singapore (19% penetration).

Mobile Dominance: 69% of VPN usage now happens on mobile devices; desktop/laptop daily use is much lower.

Use Cases: While 37% use VPNs to avoid tracking, one in four still want access to region-locked streaming content—underscoring privacy and entertainment as dual drivers.

Shift in US: Paradoxically, American VPN usage fell from 46% in 2024 to 32% in 2025, reflecting confusion over privacy, shifting workplace mandates, and trust in current VPN solutions.

AI: The Dual-Edged Sword in Secure Browsing

How AI Defends (and Attacks):

Real-Time Threat Recognition: AI enables VPNs to instantly detect anomalous traffic, filter zero-day threats, and halt phishing or malware before users are harmed.

Automated, Predictive Security: Machine learning models now block suspicious IPs, re-route data, and tighten user authentication automatically, keeping pace with rapidly evolving threats.

Countering AI-Driven Crime: Attackers are using generative AI and agent “swarms” to launch convincing deepfakes, automate malware, and operate cybercrime-as-a-service—lifting breakout speeds to under an hour for some attacks.

AI-Enhanced VPN Features:

Smart Server Selection & Optimization: AI analyzes live network conditions to pick the fastest, least-congested servers, improving speed for streaming, gaming, or remote work.

Adaptive Encryption: Dynamic selection or modification of encryption regimes based on threat levels and data type—soon including seamless integration of quantum-resistant protocols.

Personalized Privacy: AI customizes user privacy settings, recommends more secure servers, and proactively flags applications or sites trying to harvest sensitive data.

Quantum-Resistant and Decentralized VPNs: Tomorrow’s Core

Quantum Encryption Becomes Reality

Industry Rollout: By 2025, leading VPN companies like NordVPN aim to integrate quantum-resistant (post-quantum cryptography, PQC) encryption across all platforms, using protocols like ML-KEM/Kyber in hybrid modes for minimal performance loss.

Early Adoption: Early implementation of PQC-VPNs helps organizations future-proof data security and meet compliance challenges in the post-quantum era. The “harvest now, decrypt later” risk is a major driver for rapid adoption.

Competitive Advantage: Firms that adopt PQC early gain critical protection and an edge in customer trust.

Decentralized VPNs (dVPNs) and Blockchain

Decentralization Surge: By 2030, about 15% of VPN users are expected to migrate to dVPNs, which use peer-to-peer networks to eliminate central points of failure and resist mass surveillance.

Blockchain Benefits: Blockchain-based VPNs provide transparent, verifiable privacy assurances. Users can independently audit no-log policies and provider practices in real time, removing the need for blind trust.

Market Examples: Platforms like Mysterium Network (20,000+ nodes across 135+ countries) and Orchid Protocol (multi-hop, crypto-powered routing) are driving innovation and adoption, though network variability and higher costs remain challenges.

Regulatory and Ethical Frontlines

Legal Pressure: Increasingly complex AI and privacy legislation is rolling out globally, with more enforcement and stricter penalties for breaches and non-compliance anticipated through 2025 and beyond.

Corporate Ethics Gap: 91% of companies say they need to do more to reassure customers about their data practices—highlighting a growing disconnect between policy and public trust.

Conclusion: AI Is the New Backbone of Privacy—But Requires Vigilance

The fusion of AI and VPN technologies is both urgent and promising: organizations and individuals must adapt to survive against AI-powered threats.

Expect quantum-ready encryption, decentralized structures, and adaptive, AI-powered privacy controls to become standard within the decade.

The organizations who move from theoretical risk management to active, transparent, and user-centric privacy innovation will lead the next era of digital trust and security.

Introduction to LangGraph

LangGraph is a powerful framework by LangChain designed for creating stateful, multi-actor applications with LLMs. It provides the structure and tools needed to build sophisticated AI agents through a graph-based approach.

Think of LangGraph as an architect’s drafting table – it gives us the tools to design how our agent will think and act. Just as an architect draws blueprints showing how different rooms connect and how people will flow through a building, LangGraph lets us design how different capabilities will connect and how information will flow through our agent.

Key Features:

State Management: Maintain persistent state across interactions

Flexible Routing: Define complex flows between components

Persistence: Save and resume workflows

Visualization: See and understand your agent’s structure

In this tutorial, we’ll demonstrate LangGraph by building a multi-step text analysis pipeline that processes text through three stages:

Text Classification: Categorize input text into predefined categories

Entity Extraction: Identify key entities from the text

Text Summarization: Generate a concise summary of the input text

This pipeline showcases how LangGraph can be used to create a modular, extensible workflow for natural language processing tasks.

Setting Up Our Environment

Creating Our Agent’s Core Capabilities

Now we’ll create the actual skills our agent will use. Each of these capabilities is implemented as a function that performs a specific type of analysis. Check out the Full Codes here

1. Classification Node

Copy CodeCopiedUse a different Browserdef classification_node(state: State):
”’Classify the text into one of the categories: News, Blog, Research, or Other”’
prompt = PromptTemplate(
input_variables=[“text”],
template=”Classify the following text into one of the categories: News, Blog, Research, or Other.nnText:{text}nnCategory:”
)
message = HumanMessage(content=prompt.format(text=state[“text”]))
classification = llm.invoke([message]).content.strip()
return {“classification”: classification}

2. Entity Extraction Node

Copy CodeCopiedUse a different Browserdef entity_extraction_node(state: State):
”’Extract all the entities (Person, Organization, Location) from the text”’
prompt = PromptTemplate(
input_variables=[“text”],
template=”Extract all the entities (Person, Organization, Location) from the following text. Provide the result as a comma-separated list.nnText:{text}nnEntities:”
)
message = HumanMessage(content=prompt.format(text=state[“text”]))
entities = llm.invoke([message]).content.strip().split(“, “)
return {“entities”: entities}

3. Summarization Node

)
message = HumanMessage(content=prompt.format(text=state[“text”]))
summary = llm.invoke([message]).content.strip()
return {“summary”: summary}

Bringing It All Together

Now comes the most exciting part – connecting these capabilities into a coordinated system using LangGraph:

Check out the Full Codes here

Copy CodeCopiedUse a different Browser# Create our StateGraph
workflow = StateGraph(State)

# Add nodes to the graph
workflow.add_node(“classification_node”, classification_node)
workflow.add_node(“entity_extraction”, entity_extraction_node)
workflow.add_node(“summarization”, summarization_node)

# Add edges to the graph
workflow.set_entry_point(“classification_node”) # Set the entry point of the graph
workflow.add_edge(“classification_node”, “entity_extraction”)
workflow.add_edge(“entity_extraction”, “summarization”)
workflow.add_edge(“summarization”, END)

# Compile the graph
app = workflow.compile()

Workflow Structure: Our pipeline follows this path:classification_node → entity_extraction → summarization → END

Testing Our Agent

Now that we’ve built our agent, let’s see how it performs with a real-world text example:

Check out the Full Codes here

Copy CodeCopiedUse a different Browsersample_text = “”” OpenAI has announced the GPT-4 model, which is a large multimodal model that exhibits human-level performance on various professional benchmarks. It is developed to improve the alignment and safety of AI systems. Additionally, the model is designed to be more efficient and scalable than its predecessor, GPT-3. The GPT-4 model is expected to be released in the coming months and will be available to the public for research and development purposes. “””
state_input = {“text”: sample_text}
result = app.invoke(state_input)
print(“Classification:”, result[“classification”])
print(“nEntities:”, result[“entities”])
print(“nSummary:”, result[“summary”])
Classification: News Entities: [‘OpenAI’, ‘GPT-4’, ‘GPT-3’] Summary: OpenAI’s upcoming GPT-4 model is a multimodal AI that aims for human-level performance and improved safety, efficiency, and scalability compared to GPT-3.

Understanding the Power of Coordinated Processing

What makes this result particularly impressive isn’t just the individual outputs – it’s how each step builds on the others to create a complete understanding of the text.

The classification provides context that helps frame our understanding of the text type

The entity extraction identifies important names and concepts

The summarization distills the essence of the document

This mirrors human reading comprehension, where we naturally form an understanding of what kind of text it is, note important names and concepts, and form a mental summary – all while maintaining the relationships between these different aspects of understanding.

Try with Your Own Text

Now let’s try our pipeline with another text sample:

# Process the text through our pipeline your_result = app.invoke({“text”: your_text}) print(“Classification:”, your_result[“classification”])

print(“nEntities:”, your_result[“entities”])
print(“nSummary:”, your_result[“summary”])

Classification: Research Entities: [‘MIT’, ‘Google’] Summary: Recent advancements in quantum computing may threaten current encryption methods while also prompting the development of new quantum-resistant techniques.

Adding More Capabilities (Advanced)

One of the powerful aspects of LangGraph is how easily we can extend our agent with new capabilities. Let’s add a sentiment analysis node to our pipeline:

Check out the Full Codes here

Copy CodeCopiedUse a different Browser# First, let’s update our State to include sentiment
class EnhancedState(TypedDict):
text: str
classification: str
entities: List[str]
summary: str
sentiment: str

# Create our sentiment analysis node
def sentiment_node(state: EnhancedState):
”’Analyze the sentiment of the text: Positive, Negative, or Neutral”’
prompt = PromptTemplate(
input_variables=[“text”],
template=”Analyze the sentiment of the following text. Is it Positive, Negative, or Neutral?nnText:{text}nnSentiment:”
)
message = HumanMessage(content=prompt.format(text=state[“text”]))
sentiment = llm.invoke([message]).content.strip()
return {“sentiment”: sentiment}

# Create a new workflow with the enhanced state
enhanced_workflow = StateGraph(EnhancedState)

# Add the existing nodes
enhanced_workflow.add_node(“classification_node”, classification_node)
enhanced_workflow.add_node(“entity_extraction”, entity_extraction_node)
enhanced_workflow.add_node(“summarization”, summarization_node)

# Add our new sentiment node
enhanced_workflow.add_node(“sentiment_analysis”, sentiment_node)

# Create a more complex workflow with branches
enhanced_workflow.set_entry_point(“classification_node”)
enhanced_workflow.add_edge(“classification_node”, “entity_extraction”)
enhanced_workflow.add_edge(“entity_extraction”, “summarization”)
enhanced_workflow.add_edge(“summarization”, “sentiment_analysis”)
enhanced_workflow.add_edge(“sentiment_analysis”, END)

# Compile the enhanced graph
enhanced_app = enhanced_workflow.compile()

Testing the Enhanced Agent

Copy CodeCopiedUse a different Browser# Try the enhanced pipeline with the same text
enhanced_result = enhanced_app.invoke({“text”: sample_text})

print(“Classification:”, enhanced_result[“classification”])
print(“nEntities:”, enhanced_result[“entities”])
print(“nSummary:”, enhanced_result[“summary”])
print(“nSentiment:”, enhanced_result[“sentiment”])

Classification: News

Entities: [‘OpenAI’, ‘GPT-4’, ‘GPT-3’]

Summary: OpenAI’s upcoming GPT-4 model is a multimodal AI that aims for human-level performance and improved safety, efficiency, and scalability compared to GPT-3.

Sentiment: The sentiment of the text is Positive. It highlights the advancements and improvements of the GPT-4 model, emphasizing its human-level performance, efficiency, scalability, and the positive implications for AI alignment and safety. The anticipation of its release for public use further contributes to the positive tone.

Adding Conditional Edges (Advanced Logic)

Why Conditional Edges?

So far, our graph has followed a fixed linear path: classification_node → entity_extraction → summarization → (sentiment)

But in real-world applications, we often want to run certain steps only if needed. For example:

Only extract entities if the text is a News or Research article

Skip summarization if the text is very short

Add custom processing for Blog posts

LangGraph makes this easy through conditional edges – logic gates that dynamically route execution based on data in the current state.

Check out the Full Codes here

Creating a Routing Function

Copy CodeCopiedUse a different Browser# Route after classification
def route_after_classification(state: EnhancedState) -> str:
category = state[“classification”].lower() # returns: “news”, “blog”, “research”, “other”
return category in [“news”, “research”]

Define the Conditional Graph

Copy CodeCopiedUse a different Browserfrom langgraph.graph import StateGraph, END

conditional_workflow = StateGraph(EnhancedState)

# Add nodes
conditional_workflow.add_node(“classification_node”, classification_node)
conditional_workflow.add_node(“entity_extraction”, entity_extraction_node)
conditional_workflow.add_node(“summarization”, summarization_node)
conditional_workflow.add_node(“sentiment_analysis”, sentiment_node)

# Set entry point
conditional_workflow.set_entry_point(“classification_node”)

# Add conditional edge
conditional_workflow.add_conditional_edges(“classification_node”, route_after_classification, path_map={
True: “entity_extraction”,
False: “summarization”
})

# Add remaining static edges
conditional_workflow.add_edge(“entity_extraction”, “summarization”)
conditional_workflow.add_edge(“summarization”, “sentiment_analysis”)
conditional_workflow.add_edge(“sentiment_analysis”, END)

# Compile
conditional_app = conditional_workflow.compile()

NVIDIA AI Presents ThinkAct: Vision-Language-Action Reasoning via Rein …

Estimated reading time: 5 minutes

Table of contentsIntroductionThe ThinkAct FrameworkExperimental ResultsAblation Studies and Model AnalysisImplementation DetailsConclusion

Introduction

Embodied AI agents are increasingly being called upon to interpret complex, multimodal instructions and act robustly in dynamic environments. ThinkAct, presented by researchers from Nvidia and National Taiwan University, offers a breakthrough for vision-language-action (VLA) reasoning, introducing reinforced visual latent planning to bridge high-level multimodal reasoning and low-level robot control.

Typical VLA models map raw visual and language inputs directly to actions through end-to-end training, which limits reasoning, long-term planning, and adaptability. Recent methods began to incorporate intermediate chain-of-thought (CoT) reasoning or attempt RL-based optimization, but struggled with scalability, grounding, or generalization when confronted with highly variable and long-horizon robotic manipulation tasks.

The ThinkAct Framework

Dual-System Architecture

ThinkAct consists of two tightly integrated components:

Reasoning Multimodal LLM (MLLM): Performs structured, step-by-step reasoning over visual scenes and language instructions, outputting a visual plan latent that encodes high-level intent and planning context.

Action Model: A Transformer-based policy conditioned on the visual plan latent, executing the decoded trajectory as robot actions in the environment.

This design allows asynchronous operation: the LLM “thinks” and generates plans at a slow cadence, while the action module carries out fine-grained control at higher frequency.

Reinforced Visual Latent Planning

A core innovation is the reinforcement learning (RL) approach leveraging action-aligned visual rewards:

Goal Reward: Encourages the model to align the start and end positions predicted in the plan with those in demonstration trajectories, supporting goal completion.

Trajectory Reward: Regularizes the predicted visual trajectory to closely match distributional properties of expert demonstrations using dynamic time warping (DTW) distance.

Total reward rrr blends these visual rewards with a format correctness score, pushing the LLM to not only produce accurate answers but also plans that translate into physically plausible robot actions.

Training Pipeline

The multi-stage training procedure includes:

Supervised Fine-Tuning (SFT): Cold-start with manually-annotated visual trajectory and QA data to teach trajectory prediction, reasoning, and answer formatting.

Reinforced Fine-Tuning: RL optimization (using Group Relative Policy Optimization, GRPO) further incentivizes high-quality reasoning by maximizing the newly defined action-aligned rewards.

Action Adaptation: The downstream action policy is trained using imitation learning, leveraging the frozen LLM’s latent plan output to guide control across varied environments.

Inference

At inference time, given an observed scene and a language instruction, the reasoning module generates a visual plan latent, which then conditions the action module to execute a full trajectory—enabling robust performance even in new, previously unseen settings.

Experimental Results

Robot Manipulation Benchmarks

Experiments on SimplerEnv and LIBERO benchmarks demonstrate ThinkAct’s superiority:

SimplerEnv: Outperforms strong baselines (e.g., OpenVLA, DiT-Policy, TraceVLA) by 11–17% in various settings, especially excelling in long-horizon and visually diverse tasks.

LIBERO: Achieves the highest overall success rates (84.4%), excelling in spatial, object, goal, and long-horizon challenges, confirming its ability to generalize and adapt to novel skills and layouts.

Embodied Reasoning Benchmarks

On EgoPlan-Bench2, RoboVQA, and OpenEQA, ThinkAct demonstrates:

Superior multi-step and long-horizon planning accuracy.

State-of-the-art BLEU and LLM-based QA scores, reflecting improved semantic understanding and grounding for visual question answering tasks.

Few-Shot Adaptation

ThinkAct enables effective few-shot adaptation: with as few as 10 demonstrations, it achieves substantial success rate gains over other methods, highlighting the power of reasoning-guided planning for quickly learning new skills or environments.

Self-Reflection and Correction

Beyond task success, ThinkAct exhibits emergent behaviors:

Failure Detection: Recognizes execution errors (e.g., dropped objects).

Replanning: Automatically revises plans to recover and complete the task, thanks to reasoning on recent visual input sequences.

Ablation Studies and Model Analysis

Reward Ablations: Both goal and trajectory rewards are essential for structured planning and generalization. Removing either significantly drops performance, and relying only on QA-style rewards limits multi-step reasoning capability.

Reduction in Update Frequency: ThinkAct achieves a balance between reasoning (slow, planning) and action (fast, control), allowing robust performance without excessive computational demand1.

Smaller Models: The approach generalizes to smaller MLLM backbones, maintaining strong reasoning and action capabilities.

Implementation Details

Main backbone: Qwen2.5-VL 7B MLLM.

Datasets: Diverse robot and human demonstration videos (Open X-Embodiment, Something-Something V2), plus multimodal QA sets (RoboVQA, EgoPlan-Bench, Video-R1-CoT, etc.).

Uses a vision encoder (DINOv2), text encoder (CLIP), and a Q-Former for connecting reasoning output to action policy input.

Extensive experiments on real and simulated settings confirm scalability and robustness.

Conclusion

Nvidia’s ThinkAct sets a new standard for embodied AI agents, proving that reinforced visual latent planning—where agents “think before they act”—delivers robust, scalable, and adaptive performance in complex, real-world reasoning and robot manipulation tasks. Its dual-system design, reward shaping, and strong empirical results pave the way for intelligent, generalist robots capable of long-horizon planning, few-shot adaptation, and self-correction in diverse environments.

Automate the creation of handout notes using Amazon Bedrock Data Autom …

Organizations across various sectors face significant challenges when converting meeting recordings or recorded presentations into structured documentation. The process of creating handouts from presentations requires lots of manual effort, such as reviewing recordings to identify slide transitions, transcribing spoken content, capturing and organizing screenshots, synchronizing visual elements with speaker notes, and formatting content. These challenges impact productivity and scalability, especially when dealing with multiple presentation recordings, conference sessions, training materials, and educational content.
In this post, we show how you can build an automated, serverless solution to transform webinar recordings into comprehensive handouts using Amazon Bedrock Data Automation for video analysis. We walk you through the implementation of Amazon Bedrock Data Automation to transcribe and detect slide changes, as well as the use of Amazon Bedrock foundation models (FMs) for transcription refinement, combined with custom AWS Lambda functions orchestrated by AWS Step Functions. Through detailed implementation details, architectural patterns, and code, you will learn how to build a workflow that automates the handout creation process.
Amazon Bedrock Data Automation
Amazon Bedrock Data Automation uses generative AI to automate the transformation of multimodal data (such as images, videos and more) into a customizable structured format. Examples of structured formats include summaries of scenes in a video, unsafe or explicit content in text and images, or organized content based on advertisements or brands. The solution presented in this post uses Amazon Bedrock Data Automation to extract audio segments and different shots in videos.
Solution overview
Our solution uses a serverless architecture orchestrated by Step Functions to process presentation recordings into comprehensive handouts. The workflow consists of the following steps:

The workflow begins when a video is uploaded to Amazon Simple Storage Service (Amazon S3), which triggers an event notification through Amazon EventBridge rules that initiates our video processing workflow in Step Functions.
After the workflow is triggered, Amazon Bedrock Data Automation initiates a video transformation job to identify different shots in the video. In our case, this is represented by a change of slides. The workflow moves into a waiting state, and checks for the transformation job progress. If the job is in progress, the workflow returns to the waiting state. When the job is complete, the workflow continues, and we now have extracted both visual shots and spoken content.
These visual shots and spoken content feed into a synchronization step. In this Lambda function, we use the output of the Amazon Bedrock Data Automation job to match the spoken content to the correlating shots based on the matching of timestamps.
After function has matched the spoken content to the visual shots, the workflow moves into a parallel state. One of the steps of this state is the generation of screenshots. We use a FFmpeg-enabled Lambda function to create images for each identified video shot.
The other step of the parallel state is the refinement of our transformations. Amazon Bedrock processes and improves each raw transcription section through a Map state. This helps us remove speech disfluencies and improve the sentence structure.
Lastly, after the screenshots and refined transcript are created, the workflow uses a Lambda function to create handouts. We use the Python-PPTX library, which generates the final presentation with synchronized content. These final handouts are stored in Amazon S3 for distribution.

The following diagram illustrates this workflow.

If you want to try out this solution, we have created an AWS Cloud Development Kit (AWS CDK) stack available in the accompanying GitHub repo that you can deploy in your account. It deploys the Step Functions state machine to orchestrate the creation of handout notes from the presentation video recording. It also provides you with a sample video to test out the results.
To deploy and test the solution in your own account, follow the instructions in the GitHub repository’s README file. The following sections describe in more detail the technical implementation details of this solution.
Video upload and initial processing
The workflow begins with Amazon S3, which serves as the entry point for our video processing pipeline. When a video is uploaded to a dedicated S3 bucket, it triggers an event notification that, through EventBridge rules, initiates our Step Functions workflow.
Shot detection and transcription using Amazon Bedrock Data Automation
This step uses Amazon Bedrock Data Automation to detect slide transitions and create video transcriptions. To integrate this as part of the workflow, you must create an Amazon Bedrock Data Automation project. A project is a grouping of output configurations. Each project can contain standard output configurations as well as custom output blueprints for documents, images, video, and audio. The project has already been created as part of the AWS CDK stack. After you set up your project, you can process content using the InvokeDataAutomationAsync API. In our solution, we use the Step Functions service integration to execute this API call and start the asynchronous processing job. A job ID is returned for tracking the process.
The workflow must now check the status of the processing job before continuing with the handout creation process. This is done by polling Amazon Bedrock Data Automation for the job status using the GetDataAutomationStatus API on a regular basis. Using a combination of the Step Functions Wait and Choice states, we can ask the workflow to poll the API on a fixed interval. This not only gives you the ability to customize the interval depending on your needs, but it also helps you control the workflow costs, because every state transition is billed in Standard workflows, which this solution uses.
When the GetDataAutomationStatus API output shows as SUCCESS, the loop exits and the workflow continues to the next step, which will match transcripts to the visual shots.
Matching audio segments with corresponding shots
To create comprehensive handouts, you must establish a mapping between the visual shots and their corresponding audio segments. This mapping is crucial to make sure the final handouts accurately represent both the visual content and the spoken narrative of the presentation.
A shot represents a series of interrelated consecutive frames captured during the presentation, typically indicating a distinct visual state. In our presentation context, a shot corresponds to either a new slide or a significant slide animation that adds or modifies content.
An audio segment is a specific portion of an audio recording that contains uninterrupted spoken language, with minimal pauses or breaks. This segment captures a natural flow of speech. The Amazon Bedrock Data Automation output provides an audio_segments array, with each segment containing precise timing information such as the start and end time of each segment. This allows for accurate synchronization with the visual shots.
The synchronization between shots and audio segments is critical for creating accurate handouts that preserve the presentation’s narrative flow. To achieve this, we implement a Lambda function that manages the matching process in three steps:

The function retrieves the processing results from Amazon S3, which contains both the visual shots and audio segments.
It creates structured JSON arrays from these components, preparing them for the matching algorithm.
It executes a matching algorithm that analyzes the different timestamps of the audio segments and the shots, and matches them based on these timestamps. This algorithm also considers timestamp overlaps between shots and audio segments.

For each shot, the function examines audio segments and identifies those whose timestamps overlap with the shot’s duration, making sure the relevant spoken content is associated with its corresponding slide in the final handouts. The function returns the matched results directly to the Step Functions workflow, where it will serve as input for the next step, where Amazon Bedrock will refine the transcribed content and where we will create screenshots in parallel.
Screenshot generation
After you get the timestamps of each shot and associated audio segment, you can capture the slides of the presentation to create comprehensive handouts. Each detected shot from Amazon Bedrock Data Automation represents a distinct visual state in the presentation—typically a new slide or significant content change. By generating screenshots at these precise moments, we make sure our handouts accurately represent the visual flow of the original presentation.
This is done with a Lambda function using the ffmpeg-python library. This library acts as a Python binding for the FFmpeg media framework, so you can run FFmpeg terminal commands using Python methods. In our case, we can extract frames from the video at specific timestamps identified by Amazon Bedrock Data Automation. The screenshots are stored in an S3 bucket to be used in creating the handouts, as described in the following code. To use ffmpeg-python in Lambda, we created a Lambda ZIP deployment containing the required dependencies to run the code. Instructions on how to create the ZIP file can be found in our GitHub repository.
The following code shows how a screenshot is taken using ffmpeg-python. You can view the full Lambda code on GitHub.

## Taking a screenshot at a specific timestamp
ffmpeg.input(video_path, ss=timestamp).output(screenshot_path, vframes=1).run()

Transcript refinement with Amazon Bedrock
In parallel with the screenshot generation, we refine the transcript using a large language model (LLM). We do this to improve the quality of the transcript and filter out errors and speech disfluencies. This process uses an Amazon Bedrock model to enhance the quality of the matched transcription segments while maintaining content accuracy. We use a Lambda function that integrates with Amazon Bedrock through the Python Boto3 client, using a prompt to guide the model’s refinement process. The function can then process each transcript segment, instructing the model to do the following:

Fix typos and grammatical errors
Remove speech disfluencies (such as “uh” and “um”)
Maintain the original meaning and technical accuracy
Preserve the context of the presentation

In our solution, we used the following prompt with three example inputs and outputs:

prompt = ”’This is the result of a transcription.
I want you to look at this audio segment and fix the typos and mistakes present.
Feel free to use the context of the rest of the transcript to refine (but don’t leave out any info).
Leave out parts where the speaker misspoke.
Make sure to also remove works like “uh” or “um”.
Only make change to the info or sentence structure when there are mistakes.
Only give back the refined transcript as output, don’t add anything else or any context or title.
If there are no typos or mistakes, return the original object input.
Do not explain why you have or have not made any changes; I just want the JSON object.

These are examples:
Input: <an example-input>
Output: <an example-output>

Input: <an example-input>
Output: <an example-output>

Input: <an example-input>
Output: <an example-output>

Here is the object: ”’ + text

The following is an example input and output:

Input: Yeah. Um, so let’s talk a little bit about recovering from a ransomware attack, right?

Output: Yes, let’s talk a little bit about recovering from a ransomware attack.

To optimize processing speed while adhering to the maximum token limits of the Amazon Bedrock InvokeModel API, we use the Step Functions Map state. This enables parallel processing of multiple transcriptions, each corresponding to a separate video segment. Because these transcriptions must be handled individually, the Map state efficiently distributes the workload. Additionally, it reduces operational overhead by managing integration—taking an array as input, passing each element to the Lambda function, and automatically reconstructing the array upon completion.The Map state returns the refined transcript directly to the Step Functions workflow, maintaining the structure of the matched segments while providing cleaner, more professional text content for the final handout generation.
Handout generation
The final step in our workflow involves creating the handouts using the python-pptx library. This step combines the refined transcripts with the generated screenshots to create a comprehensive presentation document.
The Lambda function processes the matched segments sequentially, creating a new slide for each screenshot while adding the corresponding refined transcript as speaker notes. The implementation uses a custom Lambda layer containing the python-pptx package. To enable this functionality in Lambda, we created a custom layer using Docker. By using Docker to create our layer, we make sure the dependencies are compiled in an environment that matches the Lambda runtime. You can find the instructions to create this layer and the layer itself in our GitHub repository.
The Lambda function implementation uses python-pptx to create structured presentations:

import boto3
from pptx import Presentation
from pptx.util import Inches
import os
import json

def lambda_handler(event, context):
# Create new presentation with specific dimensions
prs = Presentation()
prs.slide_width = int(12192000) # Standard presentation width
prs.slide_height = int(6858000) # Standard presentation height

# Process each segment
for i in range(num_images):
# Add new slide
slide = prs.slides.add_slide(prs.slide_layouts[5])

# Add screenshot as full-slide image
slide.shapes.add_picture(image_path, 0, 0, width=slide_width)

# Add transcript as speaker notes
notes_slide = slide.notes_slide
transcription_text = transcription_segments[i].get(‘transcript’, ”)
notes_slide.notes_text_frame.text = transcription_text

# Save presentation
pptx_path = os.path.join(tmp_dir, “lecture_notes.pptx”)
prs.save(pptx_path)

The function processes segments sequentially, creating a presentation that combines visual shots with their corresponding audio segments, resulting in handouts ready for distribution.
The following screenshot shows an example of a generated slide with notes. The full deck has been added as a file in the GitHub repository.

Conclusion
In this post, we demonstrated how to build a serverless solution that automates the creation of handout notes from recorded slide presentations. By combining Amazon Bedrock Data Automation with custom Lambda functions, we’ve created a scalable pipeline that significantly reduces the manual effort required in creating handout materials. Our solution addresses several key challenges in content creation:

Automated detection of slide transitions, content changes, and accurate transcription of spoken content using the video modality capabilities of Amazon Bedrock Data Automation
Intelligent refinement of transcribed text using Amazon Bedrock
Synchronized visual and textual content with a custom matching algorithm
Handout generation using the ffmpeg-python and python-pptx libraries in Lambda

The serverless architecture, orchestrated by Step Functions, provides reliable execution while maintaining cost-efficiency. By using Python packages for FFmpeg and a Lambda layer for python-pptx, we’ve overcome technical limitations and created a robust solution that can handle various presentation formats and lengths. This solution can be extended and customized for different use cases, from educational institutions to corporate training programs. Certain steps such as the transcript refinement can also be improved, for instance by adding translation capabilities to account for diverse audiences.

Streamline GitHub workflows with generative AI using Amazon Bedrock an …

Customers are increasingly looking to use the power of large language models (LLMs) to solve real-world problems. However, bridging the gap between these LLMs and practical applications has been a challenge. AI agents have appeared as an innovative technology that bridges this gap.
The foundation models (FMs) available through Amazon Bedrock serve as the cognitive engine for AI agents, providing the reasoning and natural language understanding capabilities essential for interpreting user requests and generating appropriate responses. You can integrate these models with various agent frameworks and orchestration layers to create AI applications that can understand context, make decisions, and take actions. You can build with Amazon Bedrock Agents or other frameworks like LangGraph and the recently launched Strands Agent SDK.
This blog post explores how to create powerful agentic applications using the Amazon Bedrock FMs, LangGraph, and the Model Context Protocol (MCP), with a practical scenario of handling a GitHub workflow of issue analysis, code fixes, and pull request generation.
For teams seeking a managed solution to streamline GitHub workflows, Amazon Q Developer in GitHub offers native integration with GitHub repositories. It provides built-in capabilities for code generation, review, and code transformation without requiring custom agent development. While Amazon Q Developer provides out-of-the-box functionality for common development workflows, organizations with specific requirements or unique use cases may benefit from building custom solutions using Amazon Bedrock and agent frameworks. This flexibility allows teams to choose between a ready-to-use solution with Amazon Q Developer or a customized approach using Amazon Bedrock, depending on their specific needs, technical requirements, and desired level of control over the implementation.
Challenges with the current state of AI agents
Despite the remarkable advancements in AI agent technology, the current state of agent development and deployment faces significant challenges that limit their effectiveness, reliability, and broader adoption. These challenges span technical, operational, and conceptual domains, creating barriers that developers and organizations must navigate when implementing agentic solutions.
One of the significant challenges is tool integration. Although frameworks like Amazon Bedrock Agents, LangGraph, and the Strands Agent SDK provide mechanisms for agents to interact with external tools and services, the current approaches often lack standardization and flexibility. Developers must create custom integrations for each tool, define precise schemas, and handle a multitude of edge cases in tool invocation and response processing. Furthermore, the rigid nature of many tool integration frameworks means that agents struggle to adapt to changes in tool interfaces or to discover and use new capabilities dynamically.
How MCP helps in creating agents
Appearing as a response to the limitations and challenges of current agent architectures, MCP provides a standardized framework that fundamentally redefines the relationship between FMs, context management, and tool integration. This protocol addresses many of the core challenges that have hindered the broader adoption and effectiveness of AI agents, particularly in enterprise environments and complex use cases.
The following diagram illustrates an example architecture.

Tool integration is dramatically simplified through MCP’s Tool Registry and standardized invocation patterns. Developers can register tools with the registry using a consistent format, and the protocol manages the complexities of tool selection, parameter preparation, and response processing. This not only reduces the development effort required to integrate new tools but also enables more sophisticated tool usage patterns, such as tool chaining and parallel tool invocation, that are challenging to implement in current frameworks.
This combination takes advantage of the strengths of each technology—high-quality FMs in Amazon Bedrock, MCP’s context management capabilities, and LangGraph’s orchestration framework—to create agents that can tackle increasingly complex tasks with greater reliability and effectiveness.
Imagine your development team wakes up to find yesterday’s GitHub issues already analyzed, fixed, and waiting as pull requests — all handled autonomously overnight.
Recent advances in AI, particularly LLMs with code generation capabilities, have resulted in an impactful approach to development workflows. By using agents, development teams can automate simple changes—such as dependency updates or straightforward bug fixes.
Solution Overview
Amazon Bedrock is a fully managed service that makes high-performing FMs from leading AI companies and Amazon available through a unified API. Amazon Bedrock also offers a broad set of capabilities to build generative AI applications with security, privacy, and responsible AI.
LangGraph orchestrates agentic workflows through a graph-based architecture that handles complex processes and maintains context across agent interactions. It uses supervisory control patterns and memory systems for coordination. For more details, refer to Build multi-agent systems with LangGraph and Amazon Bedrock.
The Model Context Protocol (MCP) is an open standard that empowers developers to build secure, two-way connections between their data sources and AI-powered tools. The GitHub MCP Server is an MCP server that provides seamless integration with GitHub APIs. It offers a standard way for AI tools to work with GitHub’s repositories. Developers can use it to automate tasks, analyze code, and improve workflows without handling complex API calls.
This post uses these three technologies in a complementary fashion. Amazon Bedrock offers the AI capabilities for understanding issues and generating code fixes. LangGraph orchestrates the end-to-end workflow, managing the state and decision-making throughout the process. The GitHub MCP Server interfaces with GitHub repositories, providing context to the FM and implementing the generated changes. Together, these technologies enable an automation system that can understand and analyze GitHub issues, extract relevant code context, generate code fixes, create well-documented pull requests, and integrate seamlessly with existing GitHub workflows.
The figure below shows high-level view of how LangGraph integrates with GitHub through MCP while leveraging LLMs from Amazon Bedrock.

In the following sections, we explore the technical approach for building an AI-powered automation system, using Amazon Bedrock, LangGraph, and the GitHub MCP Server. We discuss the core concepts of building the solution; we don’t focus on deploying the agent or running the MCP server in the AWS environment. For a detailed explanation, refer to the GitHub repository.
Prerequisites
You must have the following prerequisites before you can deploy this solution. For this post, we use the us-west-2 AWS Region. For details on available Regions, see Amazon Bedrock endpoints and quotas.

A valid AWS account.
An AWS Identity and Access Management (IAM) role in the account that has sufficient permissions to invoke Amazon Bedrock models. If you’re planning to run your code on a Amazon SageMaker Jupyter notebook instance (rather than locally), you will also need permissions to set up and manage SageMaker resources. If you have administrator access, no action is needed for this step.
Access to Anthropic’s Claude 3.5 Haiku on Amazon Bedrock. For instructions, see Access Amazon Bedrock foundation models.
Docker or Finch to run GitHub MCP server as a container.
A fine-grained personal access token. The GitHub MCP server can use supported GitHub APIs, so enable the least permission needed for this post. Assign repository permissions for contents, issues, and pull requests.

Environment configuration and setup
The MCP server acts as a bridge between our LangGraph agent and GitHub’s API. Instead of directly calling GitHub APIs, we use the containerized the GitHub MCP Server, which provides standardized tool interfaces.
You need to define the MCP configuration using the personal access token that you defined in the prerequisites. This configuration will start the GitHub MCP Server using Docker or Finch.

mcp_config = {
“mcp”: {
“inputs”: [
{
“type”: “promptString”,
“id”: “github_token”,
“description”: “GitHub Personal Access Token”,
“password”: “true”,
}
],
“servers”: {
“github”: {
“command”: “/usr/local/bin/docker”,
“args”: [
“run”,
“-i”,
“–rm”,
“-e”,
“GITHUB_PERSONAL_ACCESS_TOKEN”,
“ghcr.io/github/github-mcp-server”,
],
“env”: {
“GITHUB_PERSONAL_ACCESS_TOKEN”: os.environ.get(“GITHUB_TOKEN”)
},
}
},
}
}

Agent state
LangGraph needs a shared state object that flows between the nodes in the workflow. This state acts as memory, allowing each step to access data from earlier steps and pass results to later ones.

class AgentState(TypedDict):
issues: List[Dict[str, Any]]
current_issue_index: int
analysis_result: Optional[Dict[str, Any]]
action_required: Optional[str]

Structured output
Instead of parsing free-form LLM responses, we use Pydantic models to enforce consistent, machine-readable outputs. This reduces parsing errors and make sure downstream nodes receive data in expected formats. The Field descriptions guide the LLM to provide exactly what we need.

class IssueAnalysis(BaseModel):
“””Analysis of the GitHub issue.”””
analysis: str = Field(
description=”Brief summary of the issue’s core problem or request.”
)
action_required: str = Field(
description=”Decision on next step. Must be one of: ‘code_change_required’, ‘no_change_needed’, ‘needs_clarification’.”
)

MCP tools integration
The load_mcp_tools function from the LangChain’s MCP adapter automatically converts the MCP server capabilities into LangChain-compatible tools. This abstraction makes it possible to use the GitHub operations (list issues, create branches, update files) as if they were built-in LangChain tools.

async def get_mcp_tools(session: ClientSession) -> List[Any]:
“””Loads tools from the connected MCP session.”””
tools = await load_mcp_tools(session)
return tools

Workflow structure
Each node is stateless — it takes the current state, performs one specific task, and returns state updates. This makes the workflow predictable, testable, and straightforward to debug. These nodes are connected using edges or conditional edges. Not every GitHub issue requires code changes. Some might be documentation requests, duplicates, or need clarification. The routing functions use the structured LLM output to dynamically decide the next step, making the workflow adaptive rather than rigid.
Finally, we start the agent by invoking the compiled graph with an initial state. The agent then follows the steps and decisions defined in the graph. The following diagram illustrates the workflow.

Agent Execution and Result
We can invoke the compiled graph with the initial_state and recursion_limit. It will fetch open issues from the given GitHub repository, analyze them one at a time, make the code changes if needed and then create the pull request in GitHub.
Considerations
To enable automated workflows, Amazon EventBridge offers an integration with GitHub through its SaaS partner event sources. After it’s configured, EventBridge receives these GitHub events in near real-time. You can create rules that match specific issue patterns and route them to various AWS services like AWS Lambda functions, AWS Step Functions state machines, or Amazon Simple Notification Service (Amazon SNS) topics for further processing. This integration enables automated workflows that can trigger your analysis pipelines or code generation processes when relevant GitHub issue activities occur.
When deploying the system, consider a phased rollout strategy. Start with a pilot phase in two or three non-critical repositories to confirm effectiveness and find issues. During this pilot phase, it’s crucial to thoroughly evaluate the solution across a diverse set of code files. This test should cover different programming languages, frameworks, formats (such as – Jupyter notebook), and varying levels of complexity in number and size of code files. Gradually expand to more repositories, prioritizing those with high maintenance burdens or standardized code patterns.
Infrastructure best practices include containerization, designing for scalability, providing high availability, and implementing comprehensive monitoring for application, system, and business metrics. Security considerations are paramount, including operating with least privilege access, proper secrets management, input validation, and vulnerability management through regular updates and security scanning.
It is crucial to align with your company’s generative AI operations and governance frameworks. Prior to deployment, verify alignment with your organization’s AI safety protocols, data handling policies, and model deployment guidelines. Although this architectural pattern offers significant benefits, you should adapt implementation to fit within your organization’s specific AI governance structure and risk management frameworks.
Clean up
Clean up your environment by completing the following steps:

Delete IAM roles and policies created specifically for this post.
Delete the local copy of this post’s code.
If you no longer need access to an Amazon Bedrock FM, you can remove access to it. For instructions, see Add or remove access to Amazon Bedrock foundation models.
Delete the personal access token. For instructions, see Deleting a personal access token.

Conclusion
The integration of Amazon Bedrock FMs with the MCP and LangGraph is a significant advancement in the field of AI agents. By addressing the fundamental challenges of context management and tool integration, this combination enables the development of more sophisticated, reliable, and powerful agentic applications.
The GitHub issues workflow scenario demonstrates benefits that include productivity enhancement, consistency improvement, faster response times, scalable maintenance, and knowledge amplification. Important insights include the role of FMs as development partners, the necessity of workflow orchestration, the importance of repository context, the need for confidence assessment, and the value of feedback loops for continuous improvement.
The future of AI-powered development automation will see trends like multi-agent collaboration systems, proactive code maintenance, context-aware code generation, enhanced developer collaboration, and ethical AI development. Challenges include skill evolution, governance complexity, quality assurance, and integration complexity, whereas opportunities include developer experience transformation, accelerated innovation, knowledge democratization, and accessibility improvements. Organizations can prepare by starting small, investing in knowledge capture, building feedback loops, developing AI literacy, and experimenting with new capabilities. The goal is to enhance developer capabilities, not replace them, fostering a collaborative future where AI and human developers work together to build better software.

Building a Comprehensive AI Agent Evaluation Framework with Metrics, R …

In this tutorial, we walk through the creation of an advanced AI evaluation framework designed to assess the performance, safety, and reliability of AI agents. We begin by implementing a comprehensive AdvancedAIEvaluator class that leverages multiple evaluation metrics, such as semantic similarity, hallucination detection, factual accuracy, toxicity, and bias analysis. Using Python’s object-oriented programming, multithreading with ThreadPoolExecutor, and robust visualization tools such as Matplotlib and Seaborn, we ensure that the evaluation system provides both depth and scalability. As we progress, we define a custom agent function and execute both batch and single-case evaluations to simulate enterprise-grade benchmarking. Check out the Full Codes here

We build the AdvancedAIEvaluator class to systematically assess AI agents using a variety of metrics like hallucination, factual accuracy, reasoning, and more. We initialize configurable parameters, define core evaluation methods, and implement advanced analysis techniques like consistency checking, adaptive sampling, and confidence intervals. With parallel processing and enterprise-grade visualization, we ensure our evaluations are scalable, interpretable, and actionable. Check out the Full Codes here

We define an advanced_example_agent that simulates realistic response behavior by matching input text to predefined answers on AI-related topics. Then, we create an instance of the AdvancedAIEvaluator with this agent and evaluate it using a curated list of test cases. Finally, we visualize the evaluation results, providing actionable insights into the agent’s performance across key metrics, including bias, relevance, and hallucination.

Sample Output

In conclusion, we’ve built a comprehensive AI evaluation pipeline that tests agent responses for correctness and safety, while also generating detailed statistical reports and insightful visual dashboards. We’ve equipped ourselves with a modular, extensible, and interpretable evaluation system that can be customized for real-world AI applications across industries. This framework enables us to continuously monitor AI performance, identify potential risks such as hallucinations or biases, and enhance the quality of responses over time. With this foundation, we are now well-prepared to conduct robust evaluations of advanced AI agents at scale.

Implementing Self-Refine Technique Using Large Language Models LLMs

This tutorial demonstrates how to implement the Self-Refine technique using Large Language Models (LLMs) with Mirascope, a powerful framework for building structured prompt workflows. Self-Refine is a prompt engineering strategy where the model evaluates its own output, generates feedback, and iteratively improves its response based on that feedback. This refinement loop can be repeated multiple times to progressively enhance the quality and accuracy of the final answer.

The Self-Refine approach is particularly effective for tasks involving reasoning, code generation, and content creation, where incremental improvements lead to significantly better results. Check out the Full Codes here

Installing the dependencies

Copy CodeCopiedUse a different Browser!pip install “mirascope[openai]”

OpenAI API Key

To get an OpenAI API key, visit https://platform.openai.com/settings/organization/api-keys and generate a new key. If you’re a new user, you may need to add billing details and make a minimum payment of $5 to activate API access. Check out the Full Codes here

Copy CodeCopiedUse a different Browserimport os
from getpass import getpass
os.environ[“OPENAI_API_KEY”] = getpass(‘Enter OpenAI API Key: ‘)

Basic Self-Refine Implementation

We begin by implementing the Self-Refine technique using Mirascope’s @openai.call and @prompt_template decorators. The process starts with generating an initial response to a user query. This response is then evaluated by the model itself, which provides constructive feedback. Finally, the model uses this feedback to generate an improved response. The self_refine function allows us to repeat this refinement process for a specified number of iterations, enhancing the quality of the output with each cycle. Check out the Full Codes here

Copy CodeCopiedUse a different Browserfrom mirascope.core import openai, prompt_template

def self_refine(query: str, depth: int) -> str:
response = call(query)
for _ in range(depth):
response = generate_new_response(query, response)
return response.content

query = “A train travels 120 km at a certain speed. If the speed had been 20 km/h faster, it would have taken 30 minutes less to cover the same distance. What was the original speed of the train?”

print(self_refine(query, 1))

Enhanced Self-Refine with Response Model

In this enhanced version, we define a structured response model MathSolution using Pydantic to capture both the solution steps and the final numerical answer. The enhanced_generate_new_response function refines the output by incorporating model-generated feedback and formatting the improved response into a well-defined schema. This approach ensures clarity, consistency, and better downstream usability of the refined answer—especially for tasks like mathematical problem-solving. Check out the Full Codes here

Copy CodeCopiedUse a different Browserfrom pydantic import BaseModel, Field

class MathSolution(BaseModel):

solution = enhanced_generate_new_response(query, response)
response = f”Steps: {solution.steps}nFinal Answer: {solution.final_answer}”
return solution

# Example usage
result = enhanced_self_refine(query, 1)
print(result)

The Enhanced Self-Refine technique proved effective in accurately solving the given mathematical problem:

“A train travels 120 km at a certain speed. If the speed had been 20 km/h faster, it would have taken 30 minutes less to cover the same distance. What was the original speed of the train?”

Through a single iteration of refinement, the model delivered a logically sound and step-by-step derivation leading to the correct answer of 60 km/h. This illustrates several key benefits of the Self-Refine approach:

Improved accuracy through iterative feedback-driven enhancement.

Clearer reasoning steps, including variable setup, equation formulation, and quadratic solution application.

Greater transparency, making it easier for users to understand and trust the solution.

In broader applications, this technique holds strong promise for tasks that demand accuracy, structure, and iterative improvement—ranging from technical problem solving to creative and professional writing. However, implementers should remain mindful of the trade-offs in computational cost and fine-tune the depth and feedback prompts to match their specific use case.

It’s Okay to Be “Just a Wrapper”: Why Solution-Driven AI Compani …

In today’s rapidly evolving AI landscape, many founders and observers find themselves preoccupied with the idea that successful startups must build foundational technology from scratch. Nowhere is this narrative more prevalent than among those launching so-called “LLM wrappers” — companies whose core offering builds on top of large language models (LLMs) like GPT or Claude. There’s a temptation to dismiss these businesses as lacking innovation or technical depth. But this perspective misses a deeper truth: customers don’t care if you’re “just a wrapper” — they care if you solve their problem1.

The AI Technology “Wrapper” Economy: Value is in Use, Not in Invention

Every successful company “wraps” something. Uber is a $190B behemoth, yet its platform is essentially a wrapper around taxis. Airbnb, worth $87B, is a marketplace wrapping around the concept of hotels. The real value in these businesses was not inventing taxis or hotels, but creating seamless, scalable solutions for transportation and lodging, respectively1.

The same dynamic plays out in AI. Companies like Harvey (legal AI, $5B valuation, $75M ARR), Perplexity (AI-powered search, $18B valuation, $150M monthly revenue run-rate), and Cursor (developer tools, $10B+ valuation) are thriving as “wrappers” around LLMs1. What they have in common is a relentless focus on solving real, vertical-specific problems — not building everything from scratch.

Infrastructure vs. Solutions: Why Wrappers Are Necessary

The foundation model providers — OpenAI, Anthropic, Google — are infrastructure companies. Their platforms are general-purpose and cannot possibly address every vertical, use case, or workflow. They need solution-focused wrappers to take their technology to market and unlock its full potential for specific customer needs1.

Misconceptions and Moats: Are Wrappers Sustainable?

Skeptics argue that LLM wrappers are vulnerable: what if the foundational AI providers simply build the feature themselves? This risk is real, but no different from risks faced by Uber and Airbnb during their ascents. The trick is to build distribution moats and meaningful product differentiation1.

Companies like Uber navigated local regulations, assembled vast driver networks, and earned user trust — advantages not easily replicated by infrastructure players. In AI, the same holds true: wrappers that go deep on vertical problems and deliver incremental improvements that matter to users can win on distribution, brand, and execution1.

That said, low-effort wrappers — those that do little more than call an API with a prompt — are likely to be crushed as infrastructure providers evolve. Mission-driven wrappers, which redefine workflows or address complex, nuanced pain points, have staying power.

Focus on Value, Not Vanity

Customers pay for outcomes, not for the technical purity of your solution. Uber users wanted reliable, affordable rides, not a revolution in vehicle engineering. AI product users want tools that make their workflow smarter, faster, or more intuitive — with little interest in the underlying tech stack1.

The Future: Will the “Wrapper” Trend Last?

It is true that barriers to entry in AI application-layer businesses appear lower today than in previous platform shifts. As LLM infrastructure rapidly improves and consolidates, not every “wrapper” will survive. The market may see a “pets.com vs. Amazon” winnowing: only those who solve real needs, build loyal user bases, and forge strong distribution will outlast the hype cycle1.

Conclusion

The “wrapper” critique misses the point. Innovative solution companies wrap technology, not because they lack ambition, but because that’s where value is created. As history shows, the future belongs to those obsessed with solving customer problems — not to those worried about the thickness of their technological layer.

Mistral-Small-3.2-24B-Instruct-2506 is now available on Amazon Bedrock …

Today, we’re excited to announce that Mistral-Small-3.2-24B-Instruct-2506—a 24-billion-parameter large language model (LLM) from Mistral AI that’s optimized for enhanced instruction following and reduced repetition errors—is available for customers through Amazon SageMaker JumpStart and Amazon Bedrock Marketplace. Amazon Bedrock Marketplace is a capability in Amazon Bedrock that developers can use to discover, test, and use over 100 popular, emerging, and specialized foundation models (FMs) alongside the current selection of industry-leading models in Amazon Bedrock.
In this post, we walk through how to discover, deploy, and use Mistral-Small-3.2-24B-Instruct-2506 through Amazon Bedrock Marketplace and with SageMaker JumpStart.
Overview of Mistral Small 3.2 (2506)
Mistral Small 3.2 (2506) is an update of Mistral-Small-3.1-24B-Instruct-2503, maintaining the same 24-billion-parameter architecture while delivering improvements in key areas. Released under Apache 2.0 license, this model maintains a balance between performance and computational efficiency. Mistral offers both the pretrained (Mistral-Small-3.1-24B-Base-2503) and instruction-tuned (Mistral-Small-3.2-24B-Instruct-2506) checkpoints of the model under Apache 2.0.
Key improvements in Mistral Small 3.2 (2506) include:

Improves in following precise instructions with 84.78% accuracy compared to 82.75% in version 3.1 from Mistral’s benchmarks
Produces twice as fewer infinite generations or repetitive answers, reducing from 2.11% to 1.29% according to Mistral
Offers a more robust and reliable function calling template for structured API interactions
Now includes image-text-to-text capabilities, allowing the model to process and reason over both textual and visual inputs. This makes it ideal for tasks such as document understanding, visual Q&A, and image-grounded content generation.

These improvements make the model particularly well-suited for enterprise applications on AWS where reliability and precision are critical. With a 128,000-token context window, the model can process extensive documents and maintain context throughout longer conversation.
SageMaker JumpStart overview
SageMaker JumpStart is a fully managed service that offers state-of-the-art FMs for various use cases such as content writing, code generation, question answering, copywriting, summarization, classification, and information retrieval. It provides a collection of pre-trained models that you can deploy quickly, accelerating the development and deployment of machine learning (ML) applications. One of the key components of SageMaker JumpStart is model hubs, which offer a vast catalog of pre-trained models, such as Mistral, for a variety of tasks.
You can now discover and deploy Mistral models in Amazon SageMaker Studio or programmatically through the Amazon SageMaker Python SDK, deriving model performance and MLOps controls with SageMaker features such as Amazon SageMaker Pipelines, Amazon SageMaker Debugger, or container logs. The model is deployed in a secure AWS environment and under your virtual private cloud (VPC) controls, helping to support data security for enterprise security needs.
Prerequisites
To deploy Mistral-Small-3.2-24B-Instruct-2506, you must have the following prerequisites:

Reasoning of complex figures
VLMs excel at interpreting and reasoning about complex figures, charts, and diagrams. In this particular use case, we use Mistral-Small-3.2-24B-Instruct-2506 to analyze an intricate image containing GDP data. Its advanced capabilities in document understanding and complex figure analysis make it well-suited for extracting insights from visual representations of economic data. By processing both the visual elements and accompanying text, Mistral Small 2506 can provide detailed interpretations and reasoned analysis of the GDP figures presented in the image.
We use the following input image.

We have defined helper functions to invoke the model using the Amazon Bedrock Converse API:

def get_image_format(image_path):
with Image.open(image_path) as img:
# Normalize the format to a known valid one
fmt = img.format.lower() if img.format else ‘jpeg’
# Convert ‘jpg’ to ‘jpeg’
if fmt == ‘jpg’:
fmt = ‘jpeg’
return fmt

def call_bedrock_model(model_id=None, prompt=””, image_paths=None, system_prompt=””, temperature=0.6, top_p=0.9, max_tokens=3000):

if isinstance(image_paths, str):
image_paths = [image_paths]
if image_paths is None:
image_paths = []

# Start building the content array for the user message
content_blocks = []

# Include a text block if prompt is provided
if prompt.strip():
content_blocks.append({“text”: prompt})

# Add images as raw bytes
for img_path in image_paths:
fmt = get_image_format(img_path)
# Read the raw bytes of the image (no base64 encoding!)
with open(img_path, ‘rb’) as f:
image_raw_bytes = f.read()

content_blocks.append({
“image”: {
“format”: fmt,
“source”: {
“bytes”: image_raw_bytes
}
}
})

# Construct the messages structure
messages = [
{
“role”: “user”,
“content”: content_blocks
}
]

# Prepare additional kwargs if system prompts are provided
kwargs = {}

kwargs[“system”] = [{“text”: system_prompt}]

# Build the arguments for the `converse` call
converse_kwargs = {
“messages”: messages,
“inferenceConfig”: {
“maxTokens”: 4000,
“temperature”: temperature,
“topP”: top_p
},
**kwargs
}

converse_kwargs[“modelId”] = model_id

# Call the converse API
try:
response = client.converse(**converse_kwargs)

# Parse the assistant response
assistant_message = response.get(‘output’, {}).get(‘message’, {})
assistant_content = assistant_message.get(‘content’, [])
result_text = “”.join(block.get(‘text’, ”) for block in assistant_content)
except Exception as e:
result_text = f”Error message: {e}”
return result_text

Our prompt and input payload are as follows:

import boto3
import base64
import json
from PIL import Image
from botocore.exceptions import ClientError

# Create a Bedrock Runtime client in the AWS Region you want to use.
client = boto3.client(“bedrock-runtime”, region_name=”us-west-2″)

system_prompt=’You are a Global Economist.’
task = ‘List the top 5 countries in Europe with the highest GDP’
image_path = ‘./image_data/gdp.png’

print(‘Input Image:nn’)
Image.open(image_path).show()

response = call_bedrock_model(model_id=endpoint_arn,
prompt=task,
system_prompt=system_prompt,
image_paths = image_path)

print(f’nResponse from the model:nn{response}’)

The following is a response using the Converse API:

Based on the image provided, the top 5 countries in Europe with the highest GDP are:

1. **Germany**: $3.99T (4.65%)
2. **United Kingdom**: $2.82T (3.29%)
3. **France**: $2.78T (3.24%)
4. **Italy**: $2.07T (2.42%)
5. **Spain**: $1.43T (1.66%)

These countries are highlighted in green, indicating their location in the Europe region.

“content”: prompt
}
],
“max_tokens”: 4000,
“temperature”: 0.15,
“top_p”: 0.9,
}

response = predictor.predict(payload)
print(response[‘choices’][0][‘message’][‘content’])
We get following response:

Hello! 😊 How can I assist you today?

Vision reasoning example
Using the multimodal capabilities of Mistral-Small-3.2-24B-Instruct-2506, you can process both text and images for comprehensive analysis. The following example highlights how the model can simultaneously analyze a tuition ROI chart to extract visual patterns and data points. The following image is the input chart.png.

Our prompt and input payload are as follows:

# Read and encode the image
image_path = “chart.png”
with open(image_path, “rb”) as image_file:
base64_image = base64.b64encode(image_file.read()).decode(‘utf-8’)

# Create a prompt focused on visual analysis of the box plot chart
visual_prompt = “””Please analyze this box plot chart showing the relationship between Annual Tuition (x-axis) and 
40-Year Net Present Value (y-axis) in US$. 
Describe the key trend between tuition and net present value shown in this chart. What’s one notable insight?”””

# Create payload with image input
payload = {
“messages”: [
{
“role”: “user”,
“content”: [
{“type”: “text”, “text”: visual_prompt},
{“type”: “image_url”, “image_url”: {“url”: f”data:image/png;base64,{base64_image}”}}
]
}
],
“max_tokens”: 800,
“temperature”: 0.15
}

# Make a prediction
response = predictor.predict(payload)

# Display the visual analysis
message = response[‘choices’][0][‘message’]
if message.get(‘content’):
print(“Vision Analysis:”)
print(message[‘content’])

We get following response:

Vision Analysis:
This box plot chart illustrates the relationship between annual tuition costs (x-axis) and the 40-year net present value (NPV) in US dollars (y-axis). Each box plot represents a range of annual tuition costs, showing the distribution of NPV values within that range.

### Key Trend:
1. **General Distribution**: Across all tuition ranges, the median 40-year NPV (indicated by the line inside each box) appears to be relatively consistent, hovering around the $1,000,000 mark.
2. **Variability**: The spread of NPV values (indicated by the height of the boxes and whiskers) is wider for higher tuition ranges, suggesting greater variability in outcomes for more expensive schools.
3. **Outliers**: There are several outliers, particularly in the higher tuition ranges (e.g., 35-40k, 40-45k, and >50k), indicating that some individuals experience significantly higher or lower NPVs.

### Notable Insight:
One notable insight from this chart is that higher tuition costs do not necessarily translate into a higher 40-year net present value. For example, the median NPV for the highest tuition range (>50k) is not significantly higher than that for the lowest tuition range (<5k). This suggests that the return on investment for higher tuition costs may not be proportionally greater, and other factors beyond tuition cost may play a significant role in determining long-term financial outcomes.

This insight highlights the importance of considering factors beyond just tuition costs when evaluating the potential return on investment of higher education.

Function calling example
This following example shows Mistral Small 3.2’s function calling by demonstrating how the model identifies when a user question needs external data and calls the correct function with proper parameters.Our prompt and input payload are as follows:

# Define a simple weather function
weather_function = {
“type”: “function”,
“function”: {
“name”: “get_weather”,
“description”: “Get weather for a location”,
“parameters”: {
“type”: “object”,
“properties”: {
“location”: {
“type”: “string”,
“description”: “City name”
}
},
“required”: [“location”]
}
}
}

# User question
user_question = “What’s the weather like in Seattle?”

# Create payload
payload = {
“messages”: [{“role”: “user”, “content”: user_question}],
“tools”: [weather_function],
“tool_choice”: “auto”,
“max_tokens”: 200,
“temperature”: 0.15
}

# Make prediction
response = predictor.predict(payload)

# Display raw response to see exactly what we get
print(json.dumps(response[‘choices’][0][‘message’], indent=2))

# Extract function call information from the response content
message = response[‘choices’][0][‘message’]
content = message.get(‘content’, ”)

if ‘[TOOL_CALLS]’ in content:
print(“Function call details:”, content.replace(‘[TOOL_CALLS]’, ”))

We get following response:

{
“role”: “assistant”,
“reasoning_content”: null,
“content”: “[TOOL_CALLS]get_weather{“location”: “Seattle”}”,
“tool_calls”: []
}
Function call details: get_weather{“location”: “Seattle”}

Generate suspicious transaction report drafts for financial compliance …

Financial regulations and compliance are constantly changing, and automation of compliance reporting has emerged as a game changer in the financial industry. Amazon Web Services (AWS) generative AI solutions offer a seamless and efficient approach to automate this reporting process. The integration of AWS generative AI into the compliance framework not only enhances efficiency but also instills a greater sense of confidence and trust in the financial sector by promoting precision and timely delivery of compliance reports. These solutions help financial institutions avoid the costly and reputational consequences of noncompliance. This, in turn, contributes to the overall stability and integrity of the financial ecosystem, benefiting both the industry and the consumers it serves.
Amazon Bedrock is a managed generative AI service that provides access to a wide array of advanced foundation models (FMs). It includes features that facilitate the efficient creation of generative AI applications with a strong focus on privacy and security. Getting a good response from an FM relies heavily on using efficient techniques for providing prompts to the FM. Retrieval Augmented Generation (RAG) is a pivotal approach to augmenting FM prompts with contextually relevant information from external sources. It uses vector databases such as Amazon OpenSearch Service to enable semantic searching of the contextual information.
Amazon Bedrock Knowledge Bases, powered by vector databases such as Amazon OpenSearch Serverless, helps in implementing RAG to supplement model inputs with relevant information from factual resources, thereby reducing potential hallucinations and increasing response accuracy.
Amazon Bedrock Agents enables generative AI applications to execute multistep tasks using action groups and enable interaction with APIs, knowledge bases, and FMs. Using agents, you can design intuitive and adaptable generative AI applications capable of understanding natural language queries and creating engaging dialogues to gather details required for using the FMs effectively.
A suspicious transaction report (STR) or suspicious activity report (SAR) is a type of report that a financial organization must submit to a financial regulator if they have reasonable grounds to suspect any financial transaction that has occurred or was attempted during their activities. There are stipulated timelines for filing these reports and it typically takes several hours of manual effort to create one report for one customer account.
In this post, we explore a solution that uses FMs available in Amazon Bedrock to create a draft STR. We cover how generative AI can be used to automate the manual process of draft generation using account information, transaction details, and correspondence summaries as well as creating a knowledge base of information about fraudulent entities involved in such transactions.
Solution overview
The solution uses Amazon Bedrock Knowledge Bases, Amazon Bedrock Agents, AWS Lambda, Amazon Simple Storage Service (Amazon S3), and OpenSearch Service. The workflow is as follows:

The user requests for creation of a draft STR report through the business application.
The application calls Amazon Bedrock Agents, which has been preconfigured with detailed instructions to engage in a conversational flow with the user. The agent follows these instructions to gather the required information from the user, completes the missing information by using actions groups to invoke the Lambda function, and generates the report in the specified format.
Following its instructions, the agent invokes Amazon Bedrock Knowledge Bases to find details about fraudulent entities involved in the suspicious transactions.
Amazon Bedrock Knowledge Bases queries OpenSearch Service to perform semantic search for the entities required for the report. If the information about fraudulent entities is available in Amazon Bedrock Knowledge Bases, the agent follows its instructions to generate a report for the user.
If the information isn’t found in the knowledge base, the agent uses the chat interface to prompt the user to provide the website URL that contains the relevant information. Alternatively, the user can provide a description about the fraudulent entity in the chat interface.
If the user provides a URL for a publicly accessible website, the agent follows its instructions to call the action group to invoke a Lambda function to crawl the website URL. The Lambda function scrapes the information from the website and returns it to the agent for use in the report.
The Lambda function also stores the scraped content in an S3 bucket for future use by the search index.
Amazon Bedrock Knowledge Bases can be programmed to periodically scan the S3 bucket to index the new content in OpenSearch Service.

The following diagram illustrates the solution architecture and workflow.

You can use the full code available in GitHub to deploy the solution using the AWS Cloud Development Kit (AWS CDK). Alternatively, you can follow a step-by-step process for manual deployment. We walk through both approaches in this post.
Prerequisites
To implement the solution provided in this post, you must enable model access in Amazon Bedrock for Amazon Titan Text Embeddings V2 and Anthropic Claude 3.5 Haiku.
Deploy the solution with the AWS CDK
To set up the solution using the AWS CDK, follow these steps:

Verify that the AWS CDK has been installed in your environment. For installation instructions, refer to the AWS CDK Immersion Day Workshop.
Update the AWS CDK to version 36.0.0 or higher:

npm install -g aws-cdk

Initialize the AWS CDK environment in the AWS account:

cdk bootstrap

Clone the GitHub repository containing the solution files:

git clone https://github.com/aws-samples/suspicious-financial-transactions-reporting

Navigate to the solution directory:

cd financial-transaction-report-drafting-for-compliance

Create and activate the virtual environment:

python3 -m venv .venv
source .venv/bin/activate

Activating the virtual environment differs based on the operating system. Refer to the AWS CDK workshop for information about activating in other environments.

After the virtual environment is activated, install the required dependencies:

pip install -r requirements.txt

Deploy the backend and frontend stacks:

cdk deploy -a ./app.py –all

When the deployment is complete, check these deployed stacks by visiting the AWS CloudFormation console, as shown in the following two screenshots.

Manual deployment
To implement the solution without using the AWS CDK, complete the following steps:

Set up an S3 bucket.
Create a Lambda function.
Set up Amazon Bedrock Knowledge Bases.
Set up Amazon Bedrock Agents.

Visual layouts in some screenshots in this post might look different than those on your AWS Management Console.
Set up an S3 bucket
Create an S3 bucket with a unique bucket name for the document repository, as shown in the following screenshot. This will be a data source for Amazon Bedrock Knowledge Bases.

Create the website scraper Lambda function
Create a new Lambda function called Url-Scraper using the Python 3.13 runtime to crawl and scrape the website URL provided by Amazon Bedrock Agents. The function will scrape the content, send the information to the agent, and store the contents in the S3 bucket for future references.

Error handling has been skipped in this code snippet for brevity. The full code is available in GitHub.
Create a new file called search_suspicious_party.py with the following code snippet:

import boto3
from bs4 import BeautifulSoup
import os
import re
import urllib.request
BUCKET_NAME = os.getenv(‘S3_BUCKET’)
s3 = boto3.client(‘s3′)
def get_receiving_entity_from_url(start_url):
response = urllib.request.urlopen(
urllib.request.Request(url=start_url, method=’GET’),
timeout=5)
soup = BeautifulSoup(response.read(), ‘html.parser’)
# Extract page title
title = soup.title.string if soup.title else ‘Untitled’
# Extract page content for specific HTML elements
content = ‘ ‘.join(p.get_text() for p in soup.find_all([‘p’, ‘h1’, ‘h2’, ‘h3’, ‘h4’, ‘h5’, ‘h6′]))
content = re.sub(r’s+’, ‘ ‘, content).strip()
s3.put_object(Body=content, Bucket=BUCKET_NAME, Key=f”docs/{title}.txt”)
return content

Replace the default generated code in lambda_function.py with the following code:

import json
from search-suspicious-party import *
def lambda_handler(event, context):
# apiPath should match the path specified in action group schema
if event[‘apiPath’] == ‘/get-receiving-entity-details’:
# Extract the property from request data
start_url = get_named_property(event, ‘start_url’)
scraped_text = get_receiving_entity_from_url(start_url)
action_response = {
‘actionGroup’: event[‘actionGroup’],
‘apiPath’: event[‘apiPath’],
‘httpMethod’: event[‘httpMethod’],
‘httpStatusCode’: 200,
‘responseBody’: {
‘application/json’: {
‘body’: json.dumps({‘scraped_text’: scraped_text})
}
}
}
return {‘response’: action_response}
# Return an error if apiPath is not recognized
return {
‘statusCode’: 400,
‘body’: json.dumps({‘error’: ‘Invalid API path’})
}
def get_named_property(event, name):
return next(
item for item in
event[‘requestBody’][‘content’][‘application/json’][‘properties’]
if item[‘name’] == name
)[‘value’]

Configure the Lambda function
Set up a Lambda environment variable S3_BUCKET, as shown in the following screenshot. For Value, use the S3 bucket you created previously.

Increase the timeout duration for Lambda function to 30 seconds. You can adjust this value based on the time it takes for the crawler to complete its work.

Set up Amazon Bedrock Knowledge Bases
Complete the following steps to create a new knowledge base in Amazon Bedrock. This knowledge base will use OpenSearch Serverless to index the fraudulent entity data stored in Amazon S3. For more information, refer to Create a knowledge base by connecting to a data source in Amazon Bedrock Knowledge Bases.

On the Amazon Bedrock console, choose Knowledge bases in the navigation pane and choose Create knowledge base.
For Knowledge base name, enter a name (for example, str-knowledge-base).
For Service role name, keep the default system generated value.

Select Amazon S3 as the data source.

Configure the Amazon S3 data source:

For Data source name, enter a name (for example, knowledge-base-data-source-s3).
For S3 URI, choose Browse S3 and choose the bucket where information scraped by web crawler about fraudulent entities is available for the knowledge base to use.
Keep all other default values.

For Embeddings model, choose Titan Text Embeddings V2.

For Vector database, select Quick create a new vector store to create a default vector store with OpenSearch Serverless.

Review the configurations and choose Create knowledge base.

After the knowledge base is successfully created, you can see the knowledge base ID, which you will need when creating the agent in Amazon Bedrock.

Select knowledge-base-data-source-s3 from the list of data sources and choose Sync to index the documents.

Set up Amazon Bedrock Agents
To create a new agent in Amazon Bedrock, complete the following steps. For more information, refer to Create and configure agent manually.

On the Amazon Bedrock console, choose Agents in the navigation pane and choose Create Agent.
For Name, enter a name (for example, agent-str).
Choose Create.

For Agent resource role, keep the default setting (Create and use a new service role).
For Select model, choose a model provider and model name (for example, Anthropic’s Claude 3.5 Haiku)
For Instructions for the Agent, provide the instructions that allow the agent to invoke the large language model (LLM).

You can download the instructions from the agent-instructions.txt file in the GitHub repo. Refer to next section in this post to understand how to write the instructions.

Keep all other default values.
Choose Save.

Under Action groups, choose Add to create a new action group.

An action is a task the agent can perform by making API calls. A set of actions comprises an action group.

Provide an API schema that defines all the APIs in the action group.
For Action group details, enter an action group name (for example, agent-group-str-url-scraper).
For Action group type, select Define with API schemas.
For Action group invocation, select Select an existing Lambda function, which is the Lambda function that you created previously.

For Action group schema, choose Define via in-line schema editor.

Choose Create.
Under Knowledge bases, choose Add.

For Select knowledge base, choose knowledge-base-str, which you created previously, and add the following instructions:

Use the information in the knowledge-base-str knowledge base to select transaction reports.

Choose Save to save all changes.
Finally, choose Prepare to prepare this agent to get it ready for testing.

You can also create a Streamlit application to create a UI for this application. The source code is available in GitHub.
Agent instructions
Agent instructions for Amazon Bedrock Agents provide the mechanism for a multistep user interaction to gather the inputs an agent needs to invoke the LLM with a rich prompt to generate the response in the required format. Provide logical instructions in plain English. There are no predefined formats for these instructions.

Provide an overview of the task including the role:

You are a financial user creating Suspicious Transaction Report (STR) draft for a financial compliance use case.

Provide the message that the agent can use for initiating the user interaction:

Greet the user with the message “Hi <name>. Welcome to STR report drafting. How can I help?”
Ask the user to provide the transactions details. From the transaction details, capture the response in the <answer> tag and include the <thinking> tag to understand the rationale behind the response.

Specify the processing that needs to be done on the output received from the LLM:

For the transaction input provided by user, create a narrative description for financial risk reporting of the provided bank account and transaction details.
1. Add a summary of correspondence logs that includes title, summary, correspondence history, and analysis in the narrative description.
2. Add the details about the receiving entity in the narrative description. You can get details about receiving entities from the agent action group.

Provide the optional messages that the agent can use for a multistep interaction to gather the missing inputs if required:

If you don’t have knowledge about Receiving entity, you should ask the Human for more details about it with a message “Unfortunately I do not have enough context or details about the receiving entity <entity name> to provide an accurate risk assessment or summary. Can you please provide some additional background information about <entity name>? What is the URL of the <entity name> or the description?”

Specify the actions that the agent can take to process the user input using action groups:

If user provides the URL of <entity name>, call the action group <add action group name> to get the details. If user provides the description of <entity name>, then summarize and add it to the narrative description as a receiving entity.

Specify how the agent should provide the response, including the format details:

Once you have all the necessary input (financial transaction details and receiving entity details), create a detailed well-formatted draft report for financial risk reporting of the provided bank account and transaction details containing the following sections:
1. Title
2. Summary of transactions
3. Correspondence History & Analysis
4. Receiving entity summary

Test the solution
To test the solution, follow these steps:

Choose Test to start testing the agent.
Initiate the chat and observe how the agent uses the instructions you provided in the configuration step to ask for required details for generating the report.
Try different prompts, such as “Generate an STR for an account.”

The following screenshot shows an example chat.

The following screenshot shows an example chat with the prompt, “Generate an STR for account number 49179-180-2092803.”

Another option is to provide all the details at the same time, for example, “Generate an STR for account number 12345-999-7654321 with the following transactions.”

Copy and paste the sample transactions from the sample-transactions.txt file in GitHub.

The agent keeps asking for missing information, such as account number, transaction details, and correspondence history. After it has all the details, it will generate a draft STR document.
The code in GitHub also contains a sample StreamLit application that you can use to test the application.
Clean up
To avoid incurring unnecessary future charges, clean up the resources you created as part of this solution. If you created the solution using the GitHub code sample and the AWS CDK, empty the S3 bucket and delete the CloudFormation stack. If you created the solution manually, complete the following steps:

Delete the Amazon Bedrock agent.
Delete the Amazon Bedrock knowledge base.
Empty and delete the S3 bucket if you created one specifically for this solution.
Delete the Lambda function.

Conclusion
In this post, we showed how Amazon Bedrock offers a robust environment for building generative AI applications, featuring a range of advanced FMs. This fully managed service prioritizes privacy and security while helping developers create AI-driven applications efficiently. A standout feature, RAG, uses external knowledge bases to enrich AI-generated content with relevant information, backed by OpenSearch Service as its vector database.

Fine-tune and deploy Meta Llama 3.2 Vision for generative AI-powered w …

Fine-tuning of large language models (LLMs) has emerged as a crucial technique for organizations seeking to adapt powerful foundation models (FMs) to their specific needs. Rather than training models from scratch—a process that can cost millions of dollars and require extensive computational resources—companies can customize existing models with domain-specific data at a fraction of the cost. This approach has become particularly valuable as organizations across healthcare, finance, and technology sectors look to use AI for specialized tasks while maintaining cost-efficiency. However, implementing a production-grade fine-tuning solution presents several significant challenges. Organizations must navigate complex infrastructure setup requirements, enforce robust security measures, optimize performance, and establish reliable model hosting solutions.
In this post, we present a complete solution for fine-tuning and deploying the Llama-3.2-11B-Vision-Instruct model for web automation tasks. We demonstrate how to build a secure, scalable, and efficient infrastructure using AWS Deep Learning Containers (DLCs) on Amazon Elastic Kubernetes Service (Amazon EKS). By using AWS DLCs, you can gain access to well-tested environments that come with enhanced security features and pre-installed software packages, significantly simplifying the optimization of your fine-tuning process. This approach not only accelerates development, but also provides robust security and performance in production environments.
Solution overview
In this section, we explore the key components of our architecture for fine-tuning a Meta Llama model and using it for web task automation. We explore the benefits of different components and how they interact with each other, and how we can use them to build a production-grade fine-tuning pipeline.
AWS DLCs for training and hosting AI/ML workloads
At the core of our solution are AWS DLCs, which provide optimized environments for machine learning (ML) workloads. These containers come preconfigured with essential dependencies, including NVIDIA drivers, CUDA toolkit, and Elastic Fabric Adapter (EFA) support, along with preinstalled frameworks like PyTorch for model training and hosting. AWS DLCs tackle the complex challenge of packaging various software components to work harmoniously with training scripts, so you can use optimized hardware capabilities out of the box. Additionally, AWS DLCs implement unique patching algorithms and processes that continuously monitor, identify, and address security vulnerabilities, making sure the containers remain secure and up-to-date. Their pre-validated configurations significantly reduce setup time and reduce compatibility issues that often occur in ML infrastructure setup.
AWS DLCs, Amazon EKS, and Amazon EC2 for seamless infrastructure management
We deploy these DLCs on Amazon EKS, creating a robust and scalable infrastructure for model fine-tuning. Organizations can use this combination to build and manage their training infrastructure with unprecedented flexibility. Amazon EKS handles the complex container orchestration, so you can launch training jobs that run within DLCs on your desired Amazon Elastic Compute Cloud (Amazon EC2) instance, producing a production-grade environment that can scale based on training demands while maintaining consistent performance.
AWS DLCs and EFA support for high-performance networking
AWS DLCs come with pre-configured support for EFA, enabling high-throughput, low-latency communication between EC2 nodes. An EFA is a network device that you can attach to your EC2 instance to accelerate AI, ML, and high performance computing applications. DLCs are pre-installed with EFA software that is tested and compatible with the underlying EC2 instances, so you don’t have to go through the hassle of setting up the underlying components yourself. For this post, we use setup scripts to create EKS clusters and EC2 instances that will support EFA out of the box.
AWS DLCs with FSDP for enhanced memory efficiency
Our solution uses PyTorch’s built-in support for Fully Sharded Data Parallel (FSDP) training, a cutting-edge technique that dramatically reduces memory requirements during training. Unlike traditional distributed training approaches where each GPU must hold a complete model copy, FSDP shards model parameters, optimizer states, and gradients across workers. The optimized implementation of FSDP within AWS DLCs makes it possible to train larger models with limited GPU resources while maintaining training efficiency.
For more information, see Scale LLMs with PyTorch 2.0 FSDP on Amazon EKS – Part 2.
Model deployment on Amazon Bedrock
For model deployment, we use Amazon Bedrock, a fully managed service for FMs. Although we can use AWS DLCs for model hosting, we use Amazon Bedrock for this post to demonstrate diversity in service utilization.
Web automation integration
Finally, we implement the SeeAct agent, a sophisticated web automation tool, and demonstrate its integration with our hosted model on Amazon Bedrock. This combination creates a powerful system capable of understanding visual inputs and executing complex web tasks autonomously, showcasing the practical applications of our fine-tuned model.In the following sections, we demonstrate how to:

Set up an EKS cluster for AI workloads.
Use AWS DLCs to fine-tune Meta Llama 3.2 Vision using PyTorch FSDP.
Deploy the fine-tuned model on Amazon Bedrock.
Use the model with SeeAct for web task automation.

Prerequisites
You must have the following prerequisites:

An AWS account.
An AWS Identity and Access Management (IAM) role with appropriate policies. Because this post deals with creating clusters, nodes, and infrastructure, administrator-level permissions would work well. However, if you must have restricted permissions, you should at least have the following permissions: AmazonEC2FullAccess, AmazonSageMakerFullAccess, AmazonBedrockFullAccess, AmazonS3FullAccess, AWSCloudFormationFullAccess, AmazonEC2ContainerRegistryFullAccess. For more information about other IAM policies needed, see Minimum IAM policies.
The necessary dependencies installed for Amazon EKS. For instructions, see Set up to use Amazon EKS.
For this post, we use P5 instances. To request a quota increase, see Requesting a quota increase.
An EC2 key pair. For instructions, see Create a key pair for your Amazon EC2 instance.

Run export AWS_REGION=<region_name> in your bash script from where you are running the commands.
Set up the EKS cluster
In this section, we walk through the steps to create your EKS cluster and install the necessary plugins, operators, and other dependencies.
Create an EKS cluster
The simplest way to create an EKS cluster is to use the cluster configuration YAML file. You can use the following sample configuration file as a base and customize it as needed. Provide the EC2 key pair created as a prerequisite. For more configuration options, see Using Config Files.


apiVersion: eksctl.io/v1alpha5
kind: ClusterConfig

metadata:
  name: MyCluster
  region: us-west-2

managedNodeGroups:
  – name: p5
    instanceType: p5.48xlarge
    minSize: 0
    maxSize: 2
    desiredCapacity: 2
    availabilityZones: [“us-west-2a”]
    volumeSize: 1024
    ssh:
      publicKeyName: <your-ec2-key-pair>
    efaEnabled: true
    privateNetworking: true
    ## In case you have an On Demand Capacity Reservation (ODCR) and want to use it, uncomment the lines below.
    # capacityReservation:
    #   capacityReservationTarget:
    #     capacityReservationResourceGroupARN: arn:aws:resource-groups:us-west-2:897880167187:group/eks_blog_post_capacity_reservation_resource_group_p5

Run the following command to create the EKS cluster:
eksctl create cluster –config-file cluster.yamlThe following is an example output:

YYYY-MM-DD HH:mm:SS [ℹ] eksctl version x.yyy.z
YYYY-MM-DD HH:mm:SS [ℹ] using region <region_name>

YYYY-MM-DD HH:mm:SS [✔] EKS cluster “<cluster_name>” in “<region_name>” region is ready

Cluster creation might take between 15–30 minutes. After it’s created, your local ~/.kube/config file gets updated with connection information to your cluster.
Run the following command line to verify that the cluster is accessible:
kubectl get nodes
Install plugins, operators, and other dependencies
In this step, you install the necessary plugins, operators and other dependencies on your EKS cluster. This is necessary to run the fine-tuning on the correct node and save the model.

Install the NVIDIA Kubernetes device plugin:

kubectl create -f https://raw.githubusercontent.com/NVIDIA/k8s-device-plugin/v0.17.0/deployments/static/nvidia-device-plugin.yml

Install the AWS EFA Kubernetes device plugin:

helm repo add eks https://aws.github.io/eks-charts
git clone -b v0.0.190 https://github.com/aws/eks-charts.git
cd  eks-charts/stable
helm install efa ./aws-efa-k8s-device-plugin -n kube-system
cd ../..

Delete aws-efa-k8s-device-plugin-daemonset by running the following command:

kubectl delete daemonset aws-efa-k8s-device-plugin-daemonset -n kube-system

Clone the code locally that with help with setup and fine-tuning:

git clone https://github.com/aws-samples/aws-do-eks.git
cd aws-do-eks
git checkout f59007ee50117b547305f3b8475c8e1b4db5a1d5

ftar -xzf patch-aws-do-eks.tar.gz
cd patch-aws-do-eks/
git am *.patch
cd ../..

Install etcd for running distributed training with PyTorch:

kubectl apply -f aws-do-eks/Container-Root/eks/deployment/etcd/etcd-deployment.yaml

Deploy the FSx CSI driver for saving the model after fine-tuning:

Enter into the fsx folder:

cd aws-do-eks/Container-Root/eks/deployment/csi/fsx/

Edit the fsx.conf file to modify the CLUSTER_NAME, CLUSTER_REGION, and CLUSTER_ZONE values to your cluster specific data:

vi fsx.conf

Deploy the FSX CSI driver:

./deploy.sh

Deploy the Kubeflow Training Operator that will be used to run the fine-tuning job:

Change the location to the following:

cd aws-do-eks/Container-Root/eks/deployment/kubeflow/training-operator/

Deploy the Kubeflow Training Operator:

./deploy.sh

Deploy the Kubeflow MPI Operator for running NCCL tests:

Run deploy.sh from the following GitHub repo.
Change the location to the following:

cd aws-do-eks/Container-Root/eks/deployment/kubeflow/mpi-operator/

Deploy the Kubeflow MPI Operator:

./deploy.sh

Fine-tune Meta Llama 3.2 Vision using DLCs on Amazon EKS
This section outlines the process for fine-tuning the Meta Llama 3.2 Vision model using PyTorch FSDP on Amazon EKS. We use the DLCs as the base image to run our training jobs.
Configure the setup needed for fine-tuning
Complete the following steps to configure the setup for fine-tuning:

Create a Hugging Face account and get a Hugging Face security token.
Enter into the fsdp folder:

cd Container-Root/eks/deployment/distributed-training/pytorch/pytorchjob/fsdp

Create a Persistent Volume Claim (PVC) that will use the underlying FSx CSI driver that you installed earlier:

kubectl apply -f pvc.yaml

Monitor kubectl get pvc fsx-claim and make sure it reached BOUND status. You can then go to the Amazon EKS console to see an unnamed volume created without a name. You can let this happen in the background, but before you run the ./run.sh command to run the fine-tuning job in a later step, make sure the BOUND status is achieved.

To configure the environment, open the .env file and modify the following variables:

HF_TOKEN: Add the Hugging Face token that you generated earlier.
S3_LOCATION: Add the Amazon Simple Storage Service (Amazon S3) location where you want to store the fine-tuned model after the training is complete.

Create the required resource YAMLs:

./deploy.sh

This line uses the values in the .env file to generate new YAML files that will eventually be used for model deployment.

Build and push the container image:

./login-dlc.sh
./build.sh
./push.sh

Run the fine-tuning job
In this step, we use the upstream DLCs and add the training scripts within the image for running the training.
Make sure that you have requested access to the Meta Llama 3.2 Vision model on Hugging Face. Continue to the next step after permission has been granted.
Execute the fine-tuning job:

./run.sh

For our use case, the job took 1.5 hours to complete. The script uses the following PyTorch command that’s defined in the .env file within the fsdp folder:

“`
bash
torchrun –nnodes 1 –nproc_per_node 8  
recipes/quickstart/finetuning/finetuning.py
–enable_fsdp –lr 1e-5  –num_epochs 5
–batch_size_training 2
–model_name meta-llama/Llama-3.2-11B-Vision-Instruct
–dist_checkpoint_root_folder ./finetuned_model
–dist_checkpoint_folder fine-tuned  
–use_fast_kernels
–dataset “custom_dataset” –custom_dataset.test_split “test”
–custom_dataset.file “recipes/quickstart/finetuning/datasets/mind2web_dataset.py”  
–run_validation False –batching_strategy padding
“`

You can use the ./logs.sh command to see the training logs in both FSDP workers.
After a successful run, logs from fsdp-worker will look as follows:

Run the processing model and store output in Amazon S3
After the jobs are complete, the fine-tuned model will exist in the FSx file system. The next step is to convert the model into Hugging Face format and save it in Amazon S3 so you can access and deploy the model in the upcoming steps:kubectl apply -f model-processor.yaml
The preceding command deploys a pod on your instance that will read the model from FSx, convert it to Hugging Face type, and push it to Amazon S3. It takes approximately 8–10 minutes for this pod to run. You can monitor the logs for this using ./logs.sh or kubectl logs -l app=model-processor.
Get the location where your model has been stored in Amazon S3. This is the same Amazon S3 location that was mentioned the .env file in an earlier step. Run the following command (provide the Amazon S3 location):aws s3 cp tokenizer_config.json <S3_LOCATION>://tokenizer_config.json
This is the tokenizer config that is needed by Amazon Bedrock to import Meta Llama models so they work with the Amazon Bedrock Converse API. For more details, see Converse API code samples for custom model import.
For this post, we use the Mind2Web dataset. We have implemented code that has been adapted from the Mind2Web code for fine-tuning. The adapted code is as follows:

git clone https://github.com/meta-llama/llama-cookbook &&
cd llama-cookbook &&
git checkout a346e19df9dd1a9cddde416167732a3edd899d09 &&

Deploy the fine-tuned model on Amazon Bedrock
After you fine-tune your Meta Llama 3.2 Vision model, you have several options for deployment. This section covers one deployment method using Amazon Bedrock. With Amazon Bedrock, you can import and use your custom trained models seamlessly. Make sure your fine-tuned model is uploaded to an S3 bucket, and it’s converted to Hugging Face format. Complete the following steps to import your fine-tuned Meta Llama 3.2 Vision model:

On the Amazon Bedrock console, under Foundation models in the navigation pane, choose Imported models.
Choose Import model.
For Model name, enter a name for the model.

For Model import source, select Amazon S3 bucket.
For S3 location, enter the location of the S3 bucket containing your fine-tuned model.

Configure additional model settings as needed, then import your model.

The process might take 10–15 minutes depending on the model size to complete.
After you import your custom model, you can invoke it using the same Amazon Bedrock API as the default Meta Llama 3.2 Vision model. Just replace the model name with your imported model’s Amazon Resource Name (ARN). For detailed instructions, refer to Amazon Bedrock Custom Model Import.
You can follow the prompt formats mentioned in the following GitHub repo. For example:
What are the steps to build a docker image?<|eot_id|><|start_header_id|>assistant<|end_header_id|>
Run the agent workload using the hosted Amazon Bedrock model
Running the agent workload involves using the SeeAct framework and browser automation to start an interactive session with the AI agent and perform the browser operations. We recommend completing the steps in this section on a local machine for browser access.
Clone the SeeAct repository
Clone the customized SeeAct repository, which contains example code that can work with Amazon Bedrock, as well as a couple of test scripts:

git clone https://github.com/OSU-NLP-Group/SeeAct.git

Set up SeeAct in a local runtime environment
Complete the following steps to set up SeeAct in a local runtime environment:

Create a Python virtual environment for this demo. We use Python 3.11 in the example, but you can change to other Python versions.

python3.11 -m venv seacct-python-3-11
source seacct-python-3-11/bin/activate

Apply a patch to add the code change needed for this demo:

cd SeeAct
curl -O https://raw.githubusercontent.com/aws/deep-learning-containers/master/examples/dlc-llama-3-finetuning-and-hosting-with-agent/patch-seeact.patch
git checkout 2fdbf373f58a1aa5f626f7c5931fe251afc69c0a
git apply patch-seeact.patch

Run the following commands to install the SeeAct package and dependencies:

cd SeeAct/seeact_package
pip install .
pip install -r requirements.txt
pip install -U boto3
playwright install

Make sure you’re using the latest version of Boto3 for these steps.
Validate the browser automation tool used by SeeAct
We added a small Python script to verify the functionality of Playwright, the browser automation tool used by SeeAct:

cd SeeAct/src
python test_playwright.py

You should see a browser launched and closed after a few seconds. You should also see a screenshot being captured in SeeAct/src/example.png showing google.com.

Test Amazon Bedrock model availability
Modify the content of test_bedrock.py. Update the MODEL_ID to be your hosted Amazon Bedrock model ARN and set up the AWS connection.

Conclusion
In this post, we presented an end-to-end workflow for fine-tuning and deploying the Meta Llama 3.2 Vision model using the production-grade infrastructure of AWS. By using AWS DLCs on Amazon EKS, you can create a robust, secure, and scalable environment for model fine-tuning. The integration of advanced technologies like EFA support and FSDP training enables efficient handling of LLMs while optimizing resource usage. The deployment through Amazon Bedrock provides a streamlined path to production, and the integration with SeeAct demonstrates practical applications in web automation tasks. This solution serves as a comprehensive reference point for engineers to develop their own specialized AI applications, adapt the demonstrated approaches, and implement similar solutions for web automation, content analysis, or other domain-specific tasks requiring vision-language capabilities.

Microsoft Edge Launches Copilot Mode to Redefine Web Browsing for the …

Microsoft has taken a major leap into the future of web browsing with the launch of Copilot Mode in Edge, positioning it as the company’s first real step toward an AI-native browser. This marks a pivotal moment not just for Edge, but for the entire concept of what a browser can be in the era of agentic AI—an era where your browser isn’t just a passive tool, but an active, intelligent collaborator.

What Is Copilot Mode?

Copilot Mode is an experimental feature in Microsoft Edge that brings Microsoft’s Copilot AI into the very heart of the browsing experience. Unlike traditional browser AI assistants, Copilot Mode enables the AI to work “agentically”—meaning it can take action proactively, understand context across numerous tabs, and help users cut through web clutter. It rethinks how users interact with the web, pivoting from endless tabs and manual searches to seamless, topic-based journeys and real assistance.

Key Features

1. Multi-Tab Retrieval-Augmented Generation (RAG)

Multi-tab RAG is a flagship feature of Copilot Mode, and for good reason. With your permission, Copilot can access, analyze, and synthesize information across all your open tabs. This enables powerful use cases, such as:

Instantly comparing products across shopping sites.

Gathering research insights from multiple scientific papers.

Summarizing the best hotel options from travel tabs.

Instead of frantically switching tabs or copy-pasting information, Copilot does the heavy lifting—turning tab noise into actionable insights and strategies.

2. Contextual AI Actions

Copilot Mode is designed to anticipate what you might want to do next. It can categorize your browsing into subject-focused tasks, handle reservations, manage errands, or guide you through complex workflows—all from a unified interface. You can issue natural language commands or use voice for hands-free navigation. Soon, features like booking reservations, managing daily activities, and tailored suggestions based on browsing history will make Copilot even more “agentic”.

3. Seamless Integration

Copilot Zone: Copilot has a presence above the address bar and on every new tab, ready to chat, summarize, or take action.

Unified Search/Chat: The new tab page is streamlined into a single input—no more scattered widgets or news feeds.

Persistent Side Pane: When invoked, Copilot stays in a dynamic side pane, so you never lose sight of the original page.

4. User Control and Privacy

All Copilot actions are opt-in, with clear visual cues indicating when Copilot is active. Users retain full control over what Copilot can access—including the ability to allow or deny access to tab contents, browsing history, or credentials. Edge’s well-established privacy standards apply, ensuring your data is protected and never shared without your permission.

Getting Started with Copilot Mode

Copilot Mode is available now as an opt-in experimental feature for Windows and Mac users in most markets where Copilot is supported.

To try Copilot Mode, simply visit the Edge Copilot Mode page or enable it under Edge Settings > AI Innovations > Copilot Mode.

The feature is free for a limited time, with some usage restrictions; Microsoft hints that it may eventually become a paid offering tied to a Copilot subscription.

Creating a Knowledge Graph Using an LLM

In this tutorial, we’ll show how to create a Knowledge Graph from an unstructured document using an LLM. While traditional NLP methods have been used for extracting entities and relationships, Large Language Models (LLMs) like GPT-4o-mini make this process more accurate and context-aware. LLMs are especially useful when working with messy, unstructured data. Using Python, Mirascope, and OpenAI’s GPT-4o-mini, we’ll build a simple knowledge graph from a sample medical log.

Installing the dependencies

Copy CodeCopiedUse a different Browser!pip install “mirascope[openai]” matplotlib networkx

OpenAI API Key

To get an OpenAI API key, visit https://platform.openai.com/settings/organization/api-keys and generate a new key. If you’re a new user, you may need to add billing details and make a minimum payment of $5 to activate API access. Check out the full Codes here.

Copy CodeCopiedUse a different Browserimport os
from getpass import getpass
os.environ[“OPENAI_API_KEY”] = getpass(‘Enter OpenAI API Key: ‘)

Defining Graph Schema

Before we extract information, we need a structure to represent it. In this step, we define a simple schema for our Knowledge Graph using Pydantic. The schema includes:

Node: Represents an entity with an ID, a type (such as “Doctor” or “Medication”), and optional properties.

Edge: Represents a relationship between two nodes.

KnowledgeGraph: A container for all nodes and edges.

Check out the full Codes here.

Copy CodeCopiedUse a different Browserfrom pydantic import BaseModel, Field

class Edge(BaseModel):
source: str
target: str
relationship: str

class Node(BaseModel):
id: str
type: str
properties: dict | None = None

class KnowledgeGraph(BaseModel):
nodes: list[Node]
edges: list[Edge]

Defining the Patient Log

Now that we have a schema, let’s define the unstructured data we’ll use to generate our Knowledge Graph. Below is a sample patient log, written in natural language. It contains key events, symptoms, and observations related to a patient named Mary. Check out the full Codes here.

Copy CodeCopiedUse a different Browserpatient_log = “””
Mary called for help at 3:45 AM, reporting that she had fallen while going to the bathroom. This marks the second fall incident within a week. She complained of dizziness before the fall.

Earlier in the day, Mary was observed wandering the hallway and appeared confused when asked basic questions. She was unable to recall the names of her medications and asked the same question multiple times.

Mary skipped both lunch and dinner, stating she didn’t feel hungry. When the nurse checked her room in the evening, Mary was lying in bed with mild bruising on her left arm and complained of hip pain.

Vital signs taken at 9:00 PM showed slightly elevated blood pressure and a low-grade fever (99.8°F). Nurse also noted increased forgetfulness and possible signs of dehydration.

This behavior is similar to previous episodes reported last month.
“””

Generating the Knowledge Graph

To transform unstructured patient logs into structured insights, we use an LLM-powered function that extracts a Knowledge Graph. Each patient entry is analyzed to identify entities (like people, symptoms, events) and their relationships (such as “reported”, “has symptom”).

The generate_kg function is decorated with @openai.call, leveraging the GPT-4o-mini model and the previously defined KnowledgeGraph schema. The prompt clearly instructs the model on how to map the log into nodes and edges. Check out the full Codes here.

Copy CodeCopiedUse a different Browserfrom mirascope.core import openai, prompt_template

@openai.call(model=”gpt-4o-mini”, response_model=KnowledgeGraph)
@prompt_template(
“””
SYSTEM:
Extract a knowledge graph from this patient log.
Use Nodes to represent people, symptoms, events, and observations.
Use Edges to represent relationships like “has symptom”, “reported”, “noted”, etc.

The log:
{log_text}

Example:
Mary said help, I’ve fallen.
Node(id=”Mary”, type=”Patient”, properties={{}})
Node(id=”Fall Incident 1″, type=”Event”, properties={{“time”: “3:45 AM”}})
Edge(source=”Mary”, target=”Fall Incident 1″, relationship=”reported”)
“””
)
def generate_kg(log_text: str) -> openai.OpenAIDynamicConfig:
return {“log_text”: log_text}
kg = generate_kg(patient_log)
print(kg)

Querying the graph

Once the KnowledgeGraph has been generated from the unstructured patient log, we can use it to answer medical or behavioral queries. We define a function run() that takes a natural language question and the structured graph, and passes them into a prompt for the LLM to interpret and respond. Check out the full Codes here.

Copy CodeCopiedUse a different Browser@openai.call(model=”gpt-4o-mini”)
@prompt_template(
“””
SYSTEM:
Use the knowledge graph to answer the user’s question.

Graph:
{knowledge_graph}

USER:

“””
)
def run(question: str, knowledge_graph: KnowledgeGraph): …

Copy CodeCopiedUse a different Browserquestion = “What health risks or concerns does Mary exhibit based on her recent behavior and vitals?”
print(run(question, kg))

Visualizing the Graph

At last, we use render_graph(kg) to generate a clear and interactive visual representation of the knowledge graph, helping us better understand the patient’s condition and the connections between observed symptoms, behaviors, and medical concerns.

Copy CodeCopiedUse a different Browserimport matplotlib.pyplot as plt
import networkx as nx

Zhipu AI Just Released GLM-4.5 Series: Redefining Open-Source Agentic …

The landscape of AI foundation models is evolving rapidly, but few entries have been as significant in 2025 as the arrival of Z.ai’s GLM-4.5 series: GLM-4.5 and its lighter sibling GLM-4.5-Air. Unveiled by Zhipu AI, these models set remarkably high standards for unified agentic capabilities and open access, aiming to bridge the gap between reasoning, coding, and intelligent agents—and to do so at both massive and manageable scales.

Model Architecture and Parameters

ModelTotal ParametersActive ParametersNotabilityGLM-4.5355B32BAmong the largest open weights, top benchmark performanceGLM-4.5-Air106B12BCompact, efficient, targeting mainstream hardware compatibility

GLM-4.5 is built on a Mixture of Experts (MoE) architecture, with a total of 355 billion parameters (32 billion active at a time). This model is crafted for cutting-edge performance, targeting high-demand reasoning and agentic applications. GLM-4.5-Air, with 106B total and 12B active parameters, provides similar capabilities with a dramatically reduced hardware and compute footprint.

Hybrid Reasoning: Two Modes in One Framework

Both models introduce a hybrid reasoning approach:

Thinking Mode: Enables complex step-by-step reasoning, tool use, multi-turn planning, and autonomous agent tasks.

Non-Thinking Mode: Optimized for instant, stateless responses, making the models versatile for conversational and quick-reaction use cases.

This dual-mode design addresses both sophisticated cognitive workflows and low-latency interactive needs within a single model, empowering next-generation AI agents.

Performance Benchmarks

Z.ai benchmarked GLM-4.5 on 12 industry-standard tests (including MMLU, GSM8K, HumanEval):

GLM-4.5: Average benchmark score of 63.2, ranked third overall (second globally, top among all open-source models).

GLM-4.5-Air: Delivers a competitive 59.8, establishing itself as the leader among ~100B-parameter models.

Outperforms notable rivals in specific areas: tool-calling success rate of 90.6%, outperforming Claude 3.5 Sonnet and Kimi K2.

Particularly strong results in Chinese-language tasks and coding, with consistent SOTA results across open benchmarks.

Agentic Capabilities and Architecture

GLM-4.5 advances “Agent-native” design: core agentic functionalities (reasoning, planning, action execution) are built directly into the model architecture. This means:

Multi-step task decomposition and planning

Tool use and integration with external APIs

Complex data visualization and workflow management

Native support for reasoning and perception-action cycles

These capabilities enable end-to-end agentic applications previously reserved for smaller, hard-coded frameworks or closed-source APIs.

Efficiency, Speed, and Cost

Speculative Decoding & Multi-Token Prediction (MTP): With features like MTP, GLM-4.5 achieves 2.5×–8× faster inference than previous models, with generation speeds >100 tokens/sec on the high-speed API and up to 200 tokens/sec claimed in practice.

Memory & Hardware: GLM-4.5-Air’s 12B active design is compatible with consumer GPUs (32–64GB VRAM) and can be quantized to fit broader hardware. This enables high-performance LLMs to run locally for advanced users.

Pricing: API calls start as low as $0.11 per million input tokens and $0.28 per million output tokens—industry-leading prices for the scale and quality offered.

Open-Source Access & Ecosystem

A keystone of the GLM-4.5 series is its MIT open-source license: the base models, hybrid (thinking/non-thinking) models, and FP8 versions are all released for unrestricted commercial use and secondary development. Code, tool parsers, and reasoning engines are integrated into major LLM frameworks, including transformers, vLLM, and SGLang, with detailed repositories available on GitHub and Hugging Face.

The models can be used through major inference engines, with fine-tuning and on-premise deployment fully supported. This level of openness and flexibility contrasts sharply with the increasingly closed stance of Western rivals.

Key Technical Innovations

Multi-Token Prediction (MTP) layer for speculative decoding, dramatically boosting inference speed on CPUs and GPUs.

Unified architecture for reasoning, coding, and multimodal perception-action workflows.

Trained on 15 trillion tokens, with support for up to 128k input and 96k output context windows.

Immediate compatibility with research and production tooling, including instructions for tuning and adapting the models for new use cases.

In summary, GLM-4.5 and GLM-4.5-Air represent a major leap for open-source, agentic, and reasoning-focused foundation models. They set new standards for accessibility, performance, and unified cognitive capabilities—providing a robust backbone for the next generation of intelligent agents and developer applications.

Build a drug discovery research assistant using Strands Agents and Ama …

Drug discovery is a complex, time-intensive process that requires researchers to navigate vast amounts of scientific literature, clinical trial data, and molecular databases. Life science customers like Genentech and AstraZeneca are using AI agents and other generative AI tools to increase the speed of scientific discovery. Builders at these organizations are already using the fully managed features of Amazon Bedrock to quickly deploy domain-specific workflows for a variety of use cases, from early drug target identification to healthcare provider engagement.
However, more complex use cases might benefit from using the open source Strands Agents SDK. Strands Agents takes a model-driven approach to develop and run AI agents. It works with most model providers, including custom and internal large language model (LLM) gateways, and agents can be deployed where you would host a Python application.
In this post, we demonstrate how to create a powerful research assistant for drug discovery using Strands Agents and Amazon Bedrock. This AI assistant can search multiple scientific databases simultaneously using the Model Context Protocol (MCP), synthesize its findings, and generate comprehensive reports on drug targets, disease mechanisms, and therapeutic areas. This assistant is available as an example in the open-source healthcare and life sciences agent toolkit for you to use and adapt.
Solution overview
This solution uses Strands Agents to connect high-performing foundation models (FMs) with common life science data sources like arXiv, PubMed, and ChEMBL. It demonstrates how to quickly create MCP servers to query data and view the results in a conversational interface.
Small, focused AI agents that work together can often produce better results than a single, monolithic agent. This solution uses a team of sub-agents, each with their own FM, instructions, and tools. The following flowchart shows how the orchestrator agent (shown in orange) handles user queries and routes them to sub-agents for either information retrieval (green) or planning, synthesis, and report generation (purple).

This post focuses on building with Strands Agents in your local development environment. Refer to the Strands Agents documentation to deploy production agents on AWS Lambda, AWS Fargate, Amazon Elastic Kubernetes Service (Amazon EKS), or Amazon Elastic Compute Cloud (Amazon EC2).
In the following sections, we show how to create the research assistant in Strands Agents by defining an FM, MCP tools, and sub-agents.
Prerequisites
This solution requires Python 3.10+, strands-agents, and several additional Python packages. We strongly recommend using a virtual environment like venv or uv to manage these dependencies.
Complete the following steps to deploy the solution to your local environment:

Clone the code repository from GitHub.
Install the required Python dependencies with pip install -r requirements.txt.
Configure your AWS credentials by setting them as environment variables, adding them to a credentials file, or following another supported process.
Save your Tavily API key to a .env file in the following format: TAVILY_API_KEY=”YOUR_API_KEY”.

You also need access to the following Amazon Bedrock FMs in your AWS account:

Anthropic’s Claude 3.7 Sonnet
Anthropic’s Claude 3.5 Sonnet
Anthropic’s Claude 3.5 Haiku

Define the foundation model
We start by defining a connection to an FM in Amazon Bedrock using the Strands Agents BedrockModel class. We use Anthropic’s Claude 3.7 Sonnet as the default model. See the following code:

from strands import Agent, tool
from strands.models import BedrockModel
from strands.agent.conversation_manager import SlidingWindowConversationManager
from strands.tools.mcp import MCPClient
# Model configuration with Strands using Amazon Bedrock’s foundation models
def get_model():
model = BedrockModel(
boto_client_config=Config(
read_timeout=900,
connect_timeout=900,
retries=dict(max_attempts=3, mode=”adaptive”),
),
model_id=”us.anthropic.claude-3-7-sonnet-20250219-v1:0″,
max_tokens=64000,
temperature=0.1,
top_p=0.9,
additional_request_fields={
“thinking”: {
“type”: “disabled” # Can be enabled for reasoning mode
}
}
)
return model

Define MCP tools
MCP provides a standard for how AI applications interact with their external environments. Thousands of MCP servers already exist, including those for life science tools and datasets. This solution provides example MCP servers for:

arXiv – Open-access repository of scholarly articles
PubMed – Peer-reviewed citations for biomedical literature
ChEMBL – Curated database of bioactive molecules with drug-like properties
ClinicalTrials.gov – US government database of clinical research studies
Tavily Web Search – API to find recent news and other content from the public internet

Strands Agents streamlines the definition of MCP clients for our agent. In this example, you connect to each tool using standard I/O. However, Strands Agents also supports remote MCP servers with Streamable-HTTP Events transport. See the following code:

# MCP Clients for various scientific databases
tavily_mcp_client = MCPClient(lambda: stdio_client(
StdioServerParameters(command=”python”, args=[“application/mcp_server_tavily.py”])
))
arxiv_mcp_client = MCPClient(lambda: stdio_client(
StdioServerParameters(command=”python”, args=[“application/mcp_server_arxiv.py”])
))
pubmed_mcp_client = MCPClient(lambda: stdio_client(
StdioServerParameters(command=”python”, args=[“application/mcp_server_pubmed.py”])
))
chembl_mcp_client = MCPClient(lambda: stdio_client(
StdioServerParameters(command=”python”, args=[“application/mcp_server_chembl.py”])
))
clinicaltrials_mcp_client = MCPClient(lambda: stdio_client(
StdioServerParameters(command=”python”, args=[“application/mcp_server_clinicaltrial.py”])
))

Define specialized sub-agents
The planning agent looks at user questions and creates a plan for which sub-agents and tools to use:

@tool
def planning_agent(query: str) -> str:
“””
A specialized planning agent that analyzes the research query and determines
which tools and databases should be used for the investigation.
“””
planning_system = “””
You are a specialized planning agent for drug discovery research. Your role is to:

1. Analyze research questions to identify target proteins, compounds, or biological mechanisms
2. Determine which databases would be most relevant (Arxiv, PubMed, ChEMBL, ClinicalTrials.gov)
3. Generate specific search queries for each relevant database
4. Create a structured research plan
“””
model = get_model()
planner = Agent(
model=model,
system_prompt=planning_system,
)
response = planner(planning_prompt)
return str(response)

Similarly, the synthesis agent integrates findings from multiple sources into a single, comprehensive report:

@tool
def synthesis_agent(research_results: str) -> str:
“””
Specialized agent for synthesizing research findings into a comprehensive report.
“””
system_prompt = “””
You are a specialized synthesis agent for drug discovery research. Your role is to:

1. Integrate findings from multiple research databases
2. Create a comprehensive, coherent scientific report
3. Highlight key insights, connections, and opportunities
4. Organize information in a structured format:
– Executive Summary (300 words)
– Target Overview
– Research Landscape
– Drug Development Status
– References
“””
model = get_model()
synthesis = Agent(
model=model,
system_prompt=system_prompt,
)
response = synthesis(synthesis_prompt)
return str(response)

Define the orchestration agent
We also define an orchestration agent to coordinate the entire research workflow. This agent uses the SlidingWindowConversationManager class from Strands Agents to store the last 10 messages in the conversation. See the following code:

def create_orchestrator_agent(
history_mode,
tavily_client=None,
arxiv_client=None,
pubmed_client=None,
chembl_client=None,
clinicaltrials_client=None,
):
system = “””
You are an orchestrator agent for drug discovery research. Your role is to coordinate a multi-agent workflow:

1. COORDINATION PHASE:
– For simple queries: Answer directly WITHOUT using specialized tools
– For complex research requests: Initiate the multi-agent research workflow

2. PLANNING PHASE:
– Use the planning_agent to determine which databases to search and with what queries

3. EXECUTION PHASE:
– Route specialized search tasks to the appropriate research agents

4. SYNTHESIS PHASE:
– Use the synthesis_agent to integrate findings into a comprehensive report
– Generate a PDF report when appropriate
“””
# Aggregate all tools from specialized agents and MCP clients
tools = [planning_agent, synthesis_agent, generate_pdf_report, file_write]
# Dynamically load tools from each MCP client
if tavily_client:
tools.extend(tavily_client.list_tools_sync())
# … (similar for other clients)
conversation_manager = SlidingWindowConversationManager(
window_size=10, # Maintains context for the last 10 exchanges
)
orchestrator = Agent(
model=model,
system_prompt=system,
tools=tools,
conversation_manager=conversation_manager
)
return orchestrator

Example use case: Explore recent breast cancer research
To test out the new assistant, launch the chat interface by running streamlit run application/app.py and opening the local URL (typically http://localhost:8501) in your web browser. The following screenshot shows a typical conversation with the research agent. In this example, we ask the assistant, “Please generate a report for HER2 including recent news, recent research, related compounds, and ongoing clinical trials.” The assistant first develops a comprehensive research plan using the various tools at its disposal. It decides to start with a web search for recent news about HER2, as well as scientific articles on PubMed and arXiv. It also looks at HER2-related compounds in ChEMBL and ongoing clinical trials. It synthesizes these results into a single report and generates an output file of its findings, including citations.

The following is an excerpt of a generated report:

Comprehensive Scientific Report: HER2 in Breast Cancer Research and Treatment
1. Executive Summary
Human epidermal growth factor receptor 2 (HER2) continues to be a critical target in breast cancer research and treatment development. This report synthesizes recent findings across the HER2 landscape highlighting significant advances in understanding HER2 biology and therapeutic approaches. The emergence of antibody-drug conjugates (ADCs) represents a paradigm shift in HER2-targeted therapy, with trastuzumab deruxtecan (T-DXd, Enhertu) demonstrating remarkable efficacy in both early and advanced disease settings. The DESTINY-Breast11 trial has shown clinically meaningful improvements in pathologic complete response rates when T-DXd is followed by standard therapy in high-risk, early-stage HER2+ breast cancer, potentially establishing a new treatment paradigm.

Notably, you don’t have to define a step-by-step process to accomplish this task. By providing the assistant with a well-documented list of tools, it can decide which to use and in what order.
Clean up
If you followed this example on your local computer, you will not create new resources in your AWS account that you need to clean up. If you deployed the research assistant using one of those services, refer to the relevant service documentation for cleanup instructions.
Conclusion
In this post, we showed how Strands Agents streamlines the creation of powerful, domain-specific AI assistants. We encourage you to try this solution with your own research questions and extend it with new scientific tools. The combination of Strands Agents’s orchestration capabilities, streaming responses, and flexible configuration with the powerful language models of Amazon Bedrock creates a new paradigm for AI-assisted research. As the volume of scientific information continues to grow exponentially, frameworks like Strands Agents will become essential tools for drug discovery.
