Text-to-audio generation has emerged as a transformative approach for synthesizing sound directly from textual prompts, offering practical use in music production, gaming, and virtual experiences. Under the hood, these models typically employ Gaussian flow-based techniques such as diffusion or rectified flows. These methods model the incremental steps that transition from random noise to structured audio. While highly effective in producing high-quality soundscapes, the slow inference speeds have posed a barrier to real-time interactivity. It is particularly limiting when creative users expect an instrument-like responsiveness from these tools.

Latency is the primary issue with these systems. Current text-to-audio models can take several seconds or even minutes to generate a few seconds of audio. The core bottleneck lies in their step-based inference architecture, requiring between 50 and 100 iterations per output. Previous acceleration strategies focus on distillation methods where smaller models are trained under the supervision of larger teacher models to replicate multi-step inference in fewer steps. However, these distillation methods are computationally expensive. They demand large-scale storage for intermediate training outputs or require simultaneous operation of several models in memory, which hinders their adoption, especially on mobile or edge devices. Also, such methods often sacrifice output diversity and introduce over-saturation artifacts.

While a few adversarial post-training methods have been attempted to bypass the cost of distillation, their success has been limited. Most existing implementations rely on partial distillation for initialization or do not scale well to complex audio synthesis. Also, audio applications have seen fewer fully adversarial solutions. Tools like Presto integrate adversarial objectives but still depend on teacher models and CFG-based training for prompt adherence, which restricts their generative diversity.

Researchers from UC San Diego, Stability AI, and Arm introduced Adversarial Relativistic-Contrastive (ARC) post-training. This approach sidesteps the need for teacher models, distillation, or classifier-free guidance. Instead, ARC enhances an existing pre-trained rectified flow generator by integrating two novel training objectives: a relativistic adversarial loss and a contrastive discriminator loss. These help the generator produce high-fidelity audio in fewer steps while maintaining strong alignment with text prompts. When paired with the Stable Audio Open (SAO) framework, the result was a system capable of generating 12 seconds of 44.1 kHz stereo audio in only 75 milliseconds on an H100 GPU and around 7 seconds on mobile devices.

With ARC methodology, they introduced Stable Audio Open Small, a compact and efficient version of SAO tailored for resource-constrained environments. This model contains 497 million parameters and uses an architecture built on a latent diffusion transformer. It consists of three main components: a waveform-compressing autoencoder, a T5-based text embedding system for semantic conditioning, and a DiT (Diffusion Transformer) that operates within the latent space of the autoencoder. Stable Audio Open Small can generate stereo audio up to 11 seconds long at 44.1 kHz. It is designed to be deployed using the ‘stable-audio-tools’ library and supports ping-pong sampling, enabling efficient few-step generation. The model demonstrated exceptional inference efficiency, achieving generation speeds of under 7 seconds on a Vivo X200 Pro phone after applying dynamic Int8 quantization, which also cut RAM usage from 6.5GB to 3.6 GB. This makes it especially viable for on-device creative applications like mobile audio tools and embedded systems.

The ARC training approach involves replacing the traditional L2 loss with an adversarial formulation where generated and real samples, paired with identical prompts, are evaluated by a discriminator trained to distinguish between them. A contrastive objective teaches the discriminator to rank accurate audio-text pairs higher than mismatched ones to improve prompt relevance. These paired objectives eliminate the need for CFG while achieving better prompt adherence. Also, ARC adopts ping-pong sampling to refine the audio output through alternating denoising and re-noising cycles, reducing inference steps without compromising quality.

ARC’s performance was evaluated extensively. In objective tests, it achieved an FDopenl3 score of 84.43, a KLpasst score of 2.24, and a CLAP score of 0.27, indicating balanced quality and semantic precision. Diversity was notably strong, with a CLAP Conditional Diversity Score (CCDS) of 0.41. Real-Time Factor reached 156.42, reflecting outstanding generation speed, while GPU memory usage remained at a practical 4.06 GB. Subjectively, ARC scored 4.4 for diversity, 4.2 for quality, and 4.2 for prompt adherence in human evaluations involving 14 participants. Unlike distillation-based models like Presto, which scored higher on quality but dropped to 2.7 on diversity, ARC presented a more balanced and practical solution.

Several Key Takeaways from the Research by Stability AI on Adversarial Relativistic-Contrastive (ARC) post-training and  Stable Audio Open Small include: 

ARC post-training avoids distillation and CFG, relying on adversarial and contrastive losses.

ARC generates 12s of 44.1 kHz stereo audio in 75ms on H100 and 7s on mobile CPUs.

It achieves 0.41 CLAP Conditional Diversity Score, the highest among tested models.

Subjective scores: 4.4 (diversity), 4.2 (quality), and 4.2 (prompt adherence).

Ping-pong sampling enables few-step inference while refining output quality.

Stable Audio Open Small offers 497M parameters, supports 8-step generation, and is compatible with mobile deployments.

On Vivo X200 Pro, inference latency dropped from 15.3s to 6.6s with half the memory.

ARC and SAO Small provide real-time solutions for music, games, and creative tools.

In conclusion, the combination of ARC post-training and Stable Audio Open Small eliminates the reliance on resource-intensive distillation and classifier-free guidance, enabling researchers to deliver a streamlined adversarial framework that accelerates inference without compromising output quality or prompt adherence. ARC enables fast, diverse, and semantically rich audio synthesis in high-performance and mobile environments. With Stable Audio Open Small optimized for lightweight deployment, this research lays the groundwork for integrating responsive, generative audio tools into everyday creative workflows, from professional sound design to real-time applications on edge devices.

The banking industry has long struggled with the inefficiencies associated with repetitive processes such as information extraction, document review, and auditing. These tasks, which require significant human resources, slow down critical operations such as Know Your Customer (KYC) procedures, loan applications, and credit analysis. As a result, banks face operational challenges, including limited scalability, slow processing speeds, and high costs associated with staff training and turnover.
To address these inefficiencies, the implementation of advanced information extraction systems is crucial. These systems enable the rapid extraction of data from various financial documents—including bank statements, KYC forms, and loan applications—reducing both manual errors and processing time. As such, information extraction technology is instrumental in accelerating customer onboarding, maintaining regulatory compliance, and driving the digital transformation of the banking sector, particularly in high-volume document processing tasks.
The challenges in document processing are compounded by the need for specialized solutions that maintain high accuracy while handling sensitive financial data such as banking statements, financial statements, and company annual reports. This is where Apoidea Group, a leading AI-focused FinTech independent software vendor (ISV) based in Hong Kong, has made a significant impact. By using cutting-edge generative AI and deep learning technologies, Apoidea has developed innovative AI-powered solutions that address the unique needs of multinational banks. Their flagship product, SuperAcc, is a sophisticated document processing service featuring a set of proprietary document understanding models capable of processing diverse document types such as bank statements, financial statements, and KYC documents.
SuperAcc has demonstrated significant improvements in the banking sector. For instance, the financial spreading process, which previously required 4–6 hours, can now be completed in just 10 minutes, with staff needing less than 30 minutes to review the results. Similarly, in small and medium-sized enterprise (SME) banking, the review process for multiple bank statements spanning 6 months—used to extract critical data such as sales turnover and interbank transactions—has been reduced to just 10 minutes. This substantial reduction in processing time not only accelerates workflows but also minimizes the risk of manual errors. By automating repetitive tasks, SuperAcc enhances both operational efficiency and accuracy, using Apoidea’s self-trained machine learning (ML) models to deliver consistent, high-accuracy results in live production environments. These advancements have led to an impressive return on investment (ROI) of over 80%, showcasing the tangible benefits of implementing SuperAcc in banking operations.
AI transformation in banking faces several challenges, primarily due to stringent security and regulatory requirements. Financial institutions demand banking-grade security, necessitating compliance with standards such as ISO 9001 and ISO 27001. Additionally, AI solutions must align with responsible AI principles to facilitate transparency and fairness. Integration with legacy banking systems further complicates adoption, because these infrastructures are often outdated compared to rapidly evolving tech landscapes. Despite these challenges, SuperAcc has been successfully deployed and trusted by over 10 financial services industry (FSI) clients, demonstrating its reliability, security, and compliance in real-world banking environments.
To further enhance the capabilities of specialized information extraction solutions, advanced ML infrastructure is essential. Amazon SageMaker HyperPod offers an effective solution for provisioning resilient clusters to run ML workloads and develop state-of-the-art models. SageMaker HyperPod accelerates the development of foundation models (FMs) by removing the undifferentiated heavy lifting involved in building and maintaining large-scale compute clusters powered by thousands of accelerators such as AWS Trainium and NVIDIA A100 and H100 GPUs. Its resiliency features automatically monitor cluster instances, detecting and replacing faulty hardware automatically, allowing developers to focus on running ML workloads without worrying about infrastructure management.
Building on this foundation of specialized information extraction solutions and using the capabilities of SageMaker HyperPod, we collaborate with APOIDEA Group to explore the use of large vision language models (LVLMs) to further improve table structure recognition performance on banking and financial documents. In this post, we present our work and step-by-step code on fine-tuning the Qwen2-VL-7B-Instruct model using LLaMA-Factory on SageMaker HyperPod. Our results demonstrate significant improvements in table structure recognition accuracy and efficiency compared to the original base model and traditional methods, with particular success in handling complex financial tables and multi-page documents. Following the steps described in this post, you can also fine-tune your own model with domain-specific data to solve your information extraction challenges using the open source implementation.
Challenges in banking information extraction systems with multimodal models
Developing information extraction systems for banks presents several challenges, primarily due to the sensitive nature of documents, their complexity, and variety. For example, bank statement formats vary significantly across financial institutions, with each bank using unique layouts, different columns, transaction descriptions, and ways of presenting financial information. In some cases, documents are scanned with low quality and are poorly aligned, blurry, or faded, creating challenges for Optical Character Recognition (OCR) systems attempting to convert them into machine-readable text. Creating robust ML models is challenging due to the scarcity of clean training data. Current solutions rely on orchestrating models for tasks such as layout analysis, entity extraction, and table structure recognition. Although this modular approach addresses the issue of limited resources for training end-to-end ML models, it significantly increases system complexity and fails to fully use available information.
Models developed based on specific document features are inherently limited in their scope, restricting access to diverse and rich training data. This limitation results in upstream models, particularly those responsible for visual representation, lacking robustness. Furthermore, single-modality models fail to use the multi-faceted nature of information, potentially leading to less precise and accurate predictions. For instance, in table structure recognition tasks, models often lack the capability to reason about textual content while inferring row and column structures. Consequently, a common error is the incorrect subdivision of single rows or columns into multiple instances. Additionally, downstream models that heavily depend on upstream model outputs are susceptible to error propagation, potentially compounding inaccuracies introduced in earlier stages of processing.
Moreover, the substantial computational requirements of these multimodal systems present scalability and efficiency challenges. The necessity to maintain and update multiple models increases the operational burden, rendering large-scale document processing both resource-intensive and difficult to manage effectively. This complexity impedes the seamless integration and deployment of such systems in banking environments, where efficiency and accuracy are paramount.
The recent advances in multimodal models have demonstrated remarkable capabilities in processing complex visual and textual information. LVLMs represent a paradigm shift in document understanding, combining the robust textual processing capabilities of traditional language models with advanced visual comprehension. These models excel at tasks requiring simultaneous interpretation of text, visual elements, and their spatial relationships, making them particularly effective for financial document processing. By integrating visual and textual understanding into a unified framework, multimodal models offer a transformative approach to document analysis. Unlike traditional information extraction systems that rely on fragmented processing pipelines, these models can simultaneously analyze document layouts, extract text content, and interpret visual elements. This integrated approach significantly improves accuracy by reducing error propagation between processing stages while maintaining computational efficiency.
Advanced vision language models are typically pre-trained on large-scale multimodal datasets that include both image and text data. The pre-training process typically involves training the model on diverse datasets containing millions of images and associated text descriptions, sourced from publicly available datasets such as image-text pairs LAION-5B, Visual Question Answering (VQAv2.0), DocVQA, and others. These datasets provide a rich variety of visual content paired with textual descriptions, enabling the model to learn meaningful representations of both modalities. During pre-training, these models are trained using auto-regressive loss, where the model predicts the next token in a sequence given the previous tokens and the visual input. This approach allows the model to effectively align visual and textual features and generate coherent text responses based on the visual context. For image data specifically, modern vision-language models use pre-trained vision encoders, such as vision transformers (ViTs), as their backbone to extract visual features. These features are then fused with textual embeddings in a multimodal transformer architecture, allowing the model to understand the relationships between images and text. By pre-training on such diverse and large-scale datasets, these models develop a strong foundational understanding of visual content, which can be fine-tuned for downstream tasks like OCR, image captioning, or visual question answering. This pre-training phase is critical for enabling the model to generalize well across a wide range of vision-language tasks. The model architecture is illustrated in the following diagram.

Fine-tuning vision-language models for visual document understanding tasks offers significant advantages due to their advanced architecture and pre-trained capabilities. The model’s ability to understand and process both visual and textual data makes it inherently well-suited for extracting and interpreting text from images. Through fine-tuning on domain-specific datasets, the model can achieve superior performance in recognizing text across diverse fonts, styles, and backgrounds. This is particularly valuable in banking applications, where documents often contain specialized terminology, complex layouts, and varying quality scans.
Moreover, fine-tuning these models for visual document understanding tasks allows for domain-specific adaptation, which is crucial for achieving high precision in specialized applications. The model’s pre-trained knowledge provides a strong foundation, reducing the need for extensive training data and computational resources. Fine-tuning also enables the model to learn domain-specific nuances, such as unique terminologies or formatting conventions, further enhancing its performance. By combining a model’s general-purpose vision-language understanding with task-specific fine-tuning, you can create a highly efficient and accurate information extraction system that outperforms traditional methods, especially in challenging or niche use cases. This makes vision-language models powerful tools for advancing visual document understanding technology in both research and practical applications.

The framework also simplifies the fine-tuning process, making it accessible to both beginners and experienced developers. This democratization of LLM fine-tuning allows users to adapt models to specific tasks quickly, fostering innovation and application across various domains. The solution architecture is presented in the following diagram.

For the training infrastructure, we use SageMaker HyperPod for distributed training. SageMaker HyperPod provides a scalable and flexible environment for training and fine-tuning large-scale models. SageMaker HyperPod offers a comprehensive set of features that significantly enhance the efficiency and effectiveness of ML workflows.

These features collectively enable ML practitioners to focus on model development while using the power of distributed computing for faster training and innovation.
Refer to our GitHub repo for a step-by-step guide on fine-tuning Qwen2-VL-7B-Instruct on SageMaker HyperPod.
We start the data preprocessing using the image input and HTML output. We choose the HTML structure as the output format because it is the most common format for representing tabular data in web applications. It is straightforward to parse and visualize, and it is compatible with most web browsers for rendering on the website for manual review or modification if needed. The data preprocessing is critical for the model to learn the patterns of the expected output format and adapt the visual layout of the table. The following is one example of input image and output HTML as the ground truth.

</table>

We then use LLaMA-Factory to fine-tune the Qwen2-VL-7B-Instruct model on the preprocessed data. We use Slurm sbatch to orchestrate the distributed training script. An example of the script would be submit_train_multinode.sh. The training script uses QLoRA and data parallel distributed training on SageMaker HyperPod. Following the guidance provided, you will see output similar to the following training log.
During inference, we use vLLM for hosting the quantized model, which provides efficient memory management and optimized attention mechanisms for high-throughput inference. vLLM natively supports the Qwen2-VL series model and continues to add support for newer models, making it particularly suitable for large-scale document processing tasks. The deployment process involves applying 4-bit quantization to reduce model size while maintaining accuracy, configuring the vLLM server with optimal parameters for batch processing and memory allocation, and exposing the model through RESTful APIs for quick integration with existing document processing pipelines. For details on model deployment configuration, refer to the hosting script.
Results
Our evaluation focused on the FinTabNet dataset, which contains complex tables from S&P 500 annual reports. This dataset presents unique challenges due to its diverse table structures, including merged cells, hierarchical headers, and varying layouts. The following example demonstrates a financial table and its corresponding model-generated HTML output, rendered in a browser for visual comparison.

For quantitative evaluation, we employed the Tree Edit Distance-based Similarity (TEDS) metric, which assesses both structural and content similarity between generated HTML tables and ground truth. TEDS measures the minimum number of edit operations required to transform one tree structure into another, and TEDS-S focuses specifically on structural similarity. The following table summarizes the output on different models.

The evaluation results reveal significant advancements in our fine-tuned model’s performance. Most notably, the Qwen2-VL-7B-Instruct model demonstrated substantial improvements in both content recognition and structural understanding after fine-tuning. When compared to its base version, the model showed enhanced capabilities in accurately interpreting complex table structures and maintaining content fidelity. The fine-tuned version not only surpassed the performance of Anthropic’s Claude 3 Haiku, but also approached the accuracy levels of Anthropic’s Claude 3.5 Sonnet, while maintaining more efficient computational requirements. Particularly impressive was the model’s improved ability to handle intricate table layouts, suggesting a deeper understanding of document structure and organization. These improvements highlight the effectiveness of our fine-tuning approach in adapting the model to specialized financial document processing tasks.
Best practices
Based on our experiments, we identified several key insights and best practices for fine-tuning multimodal table structure recognition models:

Model performance is highly dependent on the quality of fine-tuning data. The closer the fine-tuning data resembles real-world datasets, the better the model performs. Using domain-specific data, we achieved a 5-point improvement in TEDS score with only 10% of the data compared to using general datasets. Notably, fine-tuning doesn’t require massive datasets; we achieved relatively good performance with just a few thousand samples. However, we observed that imbalanced datasets, particularly those lacking sufficient examples of complex elements like long tables and forms with merged cells, can lead to biased performance. Maintaining a balanced distribution of document types during fine-tuning facilitates consistent performance across various formats.
The choice of base model significantly impacts performance. More powerful base models yield better results. In our case, Qwen2-VL’s pre-trained visual and linguistic features provided a strong foundation. By freezing most parameters through QLoRA during the initial fine-tuning stages, we achieved faster convergence and better usage of pre-trained knowledge, especially with limited data. Interestingly, the model’s multilingual capabilities were preserved; fine-tuning on English datasets alone still yielded good performance on Chinese evaluation datasets. This highlights the importance of selecting a compatible base model for optimal performance.
When real-world annotated data is limited, synthetic data generation (using specific document data synthesizers) can be an effective solution. Combining real and synthetic data during fine-tuning helps mitigate out-of-domain issues, particularly for rare or domain-specific text types. This approach proved especially valuable for handling specialized financial terminology and complex document layouts.

Security
Another important aspect of our project involves addressing the security considerations essential when working with sensitive financial documents. As expected in the financial services industry, robust security measures must be incorporated throughout the ML lifecycle. These typically include data security through encryption at rest using AWS Key Management Service (AWS KMS) and in transit using TLS, implementing strict S3 bucket policies with virtual private cloud (VPC) endpoints, and following least-privilege access controls through AWS Identity and Access Management IAM roles. For training environments like SageMaker HyperPod, security considerations involve operating within private subnets in dedicated VPCs using the built-in encryption capabilities of SageMaker. Secure model hosting with vLLM requires deployment in private VPC subnets with proper Amazon API Gateway protections and token-based authentication. These security best practices for financial services make sure that sensitive financial information remains protected throughout the entire ML pipeline while enabling innovative document processing solutions in highly regulated environments.
Conclusion
Our exploration of multi-modality models for table structure recognition in banking documents has demonstrated significant improvements in both accuracy and efficiency. The fine-tuned Qwen2-VL-7B-Instruct model, trained using LLaMA-Factory on SageMaker HyperPod, has shown remarkable capabilities in handling complex financial tables and diverse document formats. These results highlight how multimodal approaches represent a transformative leap forward from traditional multistage and single modality methods, offering an end-to-end solution for modern document processing challenges.
Furthermore, using LLaMA-Factory on SageMaker HyperPod significantly streamlines the fine-tuning process, making it both more efficient and accessible. The scalable infrastructure of SageMaker HyperPod enables rapid experimentation by allowing seamless scaling of training resources. This capability facilitates faster iteration cycles, enabling researchers and developers to test multiple configurations and optimize model performance more effectively.

These solutions support a wide range of customers, including government agencies in Australia and New Zealand.
In 2024, Vxceed launched a strategy to integrate generative AI into its solutions, aiming to enhance customer experiences and boost operational efficiency. As part of this initiative, Vxceed developed LimoConnectQ using Amazon Bedrock and AWS Lambda. This solution enables efficient document searching, simplifies trip booking, and enhances operational decisions while maintaining data security and protection.
The challenge: Balancing innovation with security
Vxceed’s customers include government agencies responsible for transporting high-profile individuals, such as judiciary members and senior officials. These agencies require highly secure systems that adhere to standards like  Information Security Registered Assessors Program (IRAP), used by the Australian government to assess security posture.
Government agencies and large corporations that handle secure ground transportation face a unique challenge: providing seamless, efficient, and secure operations while adhering to strict regulatory requirements. Vxceed Technologies, a software-as-a-service (SaaS) provider specializing in ground transportation and resource planning, recognized an opportunity to enhance its LimoConnect solution with generative AI. Vxceed initially explored various AI solutions but faced a critical hurdle: verifying that customer data remained within their dedicated private environments. Existing AI offerings often processed data externally, posing security risks that their clients could not accept.
Vxceed needed AI capabilities that could function within a highly controlled environment, helping to ensure complete data privacy while enhancing operational efficiency.
This challenge led Vxceed to use Amazon Bedrock, a fully managed service that offers a choice of high-performing foundation models (FMs) from leading AI companies through a single API.
LimoConnect Q solution overview and implementation highlights
To address the challenges of secure, efficient, and intelligent ground transportation management, Vxceed developed LimoConnect Q, an AI-powered solution. LimoConnect Q’s architecture uses Amazon Bedrock, Amazon API Gateway, Amazon DynamoDB, and AWS Lambda to create a secure, scalable AI-powered transportation management system. The solution implements a multi-agent architecture, shown in the following figure where each component operates within the customer’s private AWS environment, maintaining data security, scalability, and intuitive user interactions.

Figure 1 – Vxceed’s LimoConnect Q architecture

Let’s dive further into each component in this architecture:
Conversational trip booking with intelligent orchestration using Amazon Bedrock Agents
Beyond document queries, LimoConnect Q revolutionizes trip booking by replacing traditional forms and emails with a conversational AI-driven process. Users can state their trip requirements in natural language. Key features include:

Natural language: Processes natural language booking requests based on travel context and preferences, for example:

Schedule airport pickup for dignitaries at 9 AM tomorrow to the conference center.
Book airport to my office transfer next Monday at 10 AM.

Automated data retrieval and processing: LimoConnect Q integrates with multiple data sources to:

Validate pickup and drop-off locations using geolocation services
Automates address geocoding and external API lookups, verifying accurate bookings.
Verify vehicle and driver eligibility through Amazon Bedrock Agents
Retrieve relevant trip details from past bookings and preferences

Seamless booking execution: After the request is processed, LimoConnect Q automatically:

Confirms the trip
Provides personalized recommendations based on booking history
Sends real-time booking updates and notifies relevant personnel (for example, drivers and dispatch teams)

This conversational approach minimizes manual processing, reduces booking errors, and enhances user convenience—especially for busy professionals who need a fast, friction less way to arrange transportation.
Secure RAG for policy and document querying using Amazon Bedrock Knowledge Bases
One of the most critical functionalities of LimoConnect Q is the ability to query policy documents, procedural manuals, and operational guidelines in natural language. Traditionally, accessing such information required manual searches or expert assistance, creating inefficiencies—especially when expert staff aren’t available.
Vxceed addressed these challenges by implementing a Retrieval Augmented Generation (RAG) framework. This system generates responses that align with policies, incorporate relevant facts, and consider context. The solution delivers the ability to:

Query documents in natural language: Instead of searching manually, users can ask questions like What is the protocol for VIP pickup at the airport?
Restrict AI-generated responses based on RAG: Use RAG to make sure that answers are pulled only from approved, up-to-date documents, maintaining security and compliance.
Keep sensitive data within the customer’s environment: LimoConnect Q maintains data privacy and compliance by keeping queries within the customer’s private AWS environment, providing end-to-end security.

This capability significantly improves operational efficiency, allowing users to get instant, reliable answers instead of relying on manual lookups or expert availability.
Multi-agent AI architecture for secure orchestration
Vxceed built a multi-agent AI system on Lambda to manage LimoConnect Q’s transportation workflows. The architecture comprises agents that handle dispatch, routing, and scheduling tasks while maintaining security and scalability.

Intent recognition agent: Determines whether a user request pertains to document retrieval, trip booking, or another functions.
Document retrieval agent: Handles policy queries using RAG-based retrieval.
Trip booking agent: Processes user inputs, extracting key information such as pickup and drop-off locations, time, vehicle type, passenger count, and special requests. It verifies that booking information is provided, including name, contact details, and trip preferences. The agent validates addresses using geolocation APIs for accuracy before proceeding. The agent then checks vehicle and driver availability by querying the fleet management database, retrieving real-time data on approved resources. It also interacts with a user preference database, using vector-based search to suggest personalized options.
Flight information validation agent: Verifies flight schedules.
Trip duplication agent: Checks for previously booked trips with similar details to help avoid duplicate bookings.
Return trip agent: Analyzes past trips and preferences to recommend suitable return options, considering real-time vehicle availability and driver schedules.
Data validation agent: Verifies security policy compliance.
External API agent: integrates with third-party services such as geolocation services, scheduling interfaces, and transportation databases, providing real-time data updates for optimized trip coordination.
Booking retrieval agent: Helps users retrieve existing bookings or cancel them, querying the backend database for current and past trips.

After validation, LimoConnect Q uses Lambda functions and Amazon Bedrock integrated APIs to process bookings, update databases, and manage notifications to drivers and dispatch teams. The modular architecture enables Vxceed to seamlessly add new features like driver certification tracking and compliance automation.
Built with security at its core, LimoConnect Q uses Lambda for efficient handling of query spikes while implementing robust memory isolation mechanisms. Each user session maintains temporary memory for contextual conversations without permanent storage, and strict access controls ensure session-specific data isolation, preventing cross-contamination of sensitive information. This architecture adhere to the stringent security requirements of government and enterprise customers while maintaining operational efficiency.
Using LimoConnect Q, customers have saved an average of 15 minutes per query, increased first-call resolution rates by 80 percent, and cut onboarding and training time by 50 percent.
Guardrails
LimoConnect Q uses Amazon Bedrock Guardrails to maintain professional, focused interactions. The system uses denied topics and word filters to help prevent unrelated discussions and unprofessional language, making sure that conversations remain centered on transportation needs. These guardrails constrain the system’s responses to travel-specific intents, maintaining consistent professionalism across user interactions. By implementing these controls, Vxceed makes sure that this AI solution delivers reliable, business-appropriate responses that align with their customers’ high standards for secure transportation services.
AI-powered tools for ground transportation optimization
LimoConnect Q also incorporates custom AI tools to enhance accuracy and automation across various transportation tasks:

Address geocoding and validation: AI-powered location services verify pickup and drop-off addresses, reducing errors and maintaining accurate scheduling.
Automated trip matching: The system analyzes historical booking data and user preferences to recommend the most suitable vehicle options.
Role-based access control: AI-driven security protocols enforce policies on vehicle assignments based on user roles and clearance levels.

These enhancements streamline operations, reduce manual intervention, and provide a frictionless user experience for secure transportation providers, government agencies and large enterprises.
Why Vxceed chose Amazon Bedrock
Vxceed selected Amazon Bedrock over other AI solutions because of four key advantages:

Enterprise-grade security and privacy: Amazon Bedrock provides private, encrypted AI environments that keep data within the customer’s virtual private cloud (VPC), maintaining compliance with strict security requirements.
Seamless AWS integration: LimoConnect Q runs on Vxceed’s existing AWS infrastructure, minimizing migration effort and allowing end-to-end control over data and operations.

Algorithm design and scientific discovery often demand a meticulous cycle of exploration, hypothesis testing, refinement, and validation. Traditionally, these processes rely heavily on expert intuition and manual iteration, particularly for problems rooted in combinatorics, optimization, and mathematical construction. While large language models (LLMs) have recently demonstrated promise in accelerating code generation and problem solving, their ability to autonomously generate provably correct and computationally superior algorithms remains limited—especially when solutions must generalize across diverse use cases or deliver production-grade performance.

Google DeepMind Introduces AlphaEvolve

To address these limitations, Google DeepMind has unveiled AlphaEvolve, a next-generation coding agent powered by Gemini 2.0 LLMs. AlphaEvolve is designed to automate the process of algorithm discovery using a novel fusion of large-scale language models, automated program evaluation, and evolutionary computation. Unlike conventional code assistants, AlphaEvolve autonomously rewrites and improves algorithmic code by learning from a structured feedback loop—iteratively proposing, evaluating, and evolving new candidate solutions over time.

AlphaEvolve orchestrates a pipeline where LLMs generate program mutations informed by previous high-performing solutions, while automated evaluators assign performance scores. These scores drive a continual refinement process. AlphaEvolve builds on prior systems like FunSearch but extends their scope dramatically—handling full codebases in multiple languages and optimizing for multiple objectives simultaneously.

System Architecture and Technical Advantages

The architecture of AlphaEvolve combines multiple components into an asynchronous and distributed system:

Prompt Construction: A sampler assembles prompts using previous high-scoring solutions, mathematical context, or code structure.

LLM Ensemble: A hybrid of Gemini 2.0 Pro and Gemini 2.0 Flash enables a balance between high-quality insight and rapid idea exploration.

Evaluation Framework: Custom scoring functions are used to systematically assess algorithmic performance based on predefined metrics, enabling transparent and scalable comparison.

Evolutionary Loop: AlphaEvolve maintains a database of prior programs and performance data, which it uses to inform new generations of code, balancing exploration and exploitation.

A key technical strength lies in AlphaEvolve’s flexibility. It can evolve complete programs, support multi-objective optimization, and adapt to different problem abstractions—whether evolving constructor functions, search heuristics, or entire optimization pipelines. This capability is particularly useful for problems where progress is machine-measurable, such as matrix multiplication or data center scheduling.

Results and Real-World Applications

AlphaEvolve has demonstrated robust performance across theoretical and applied domains:

Matrix Multiplication: AlphaEvolve discovered 14 new low-rank algorithms for matrix multiplication. Most notably, it found a method to multiply 4×4 complex matrices using 48 scalar multiplications—surpassing the long-standing 49-multiplication bound set by Strassen’s algorithm in 1969.

Mathematical Discovery: Applied to over 50 mathematical problems—including the Erdős minimum overlap problem and the kissing number problem in 11 dimensions—AlphaEvolve matched existing state-of-the-art constructions in ~75% of cases and outperformed them in ~20%, all while requiring minimal expert handcrafting.

Infrastructure Optimization at Google:

Data Center Scheduling: AlphaEvolve generated a scheduling heuristic that improved resource efficiency across Google’s global compute fleet, reclaiming 0.7% of stranded compute capacity—equivalent to hundreds of thousands of machines.

Kernel Engineering for Gemini: Optimized tiling heuristics yielded a 23% speedup for matrix multiplication kernels, reducing overall Gemini training time by 1%.

Hardware Design: AlphaEvolve proposed Verilog-level optimizations to TPU arithmetic circuits, contributing to area and power reductions without compromising correctness.

Compiler-Level Optimization: By modifying compiler-generated XLA intermediate representations for attention kernels, AlphaEvolve delivered a 32% performance improvement in FlashAttention execution.

These results underscore AlphaEvolve’s generality and impact—successfully discovering novel algorithms and deploying them in production-grade environments.

Conclusion

AlphaEvolve represents a significant leap forward in AI-assisted scientific and algorithmic discovery. By integrating Gemini-powered LLMs with evolutionary search and automated evaluation, AlphaEvolve transcends the limitations of prior systems—offering a scalable, general-purpose engine capable of uncovering high-performing, verifiably correct algorithms across diverse domains.

Its deployment within Google’s infrastructure—and its ability to improve upon both theoretical bounds and real-world systems—suggests a future where AI agents do not merely assist in software development but actively contribute to scientific advancement and system optimization.

PixArt-Sigma is a diffusion transformer model that is capable of image generation at 4k resolution. This model shows significant improvements over previous generation PixArt models like Pixart-Alpha and other diffusion models through dataset and architectural improvements. AWS Trainium and AWS Inferentia are purpose-built AI chips to accelerate machine learning (ML) workloads, making them ideal for cost-effective deployment of large generative models. By using these AI chips, you can achieve optimal performance and efficiency when running inference with diffusion transformer models like PixArt-Sigma.
This post is the first in a series where we will run multiple diffusion transformers on Trainium and Inferentia-powered instances. In this post, we show how you can deploy PixArt-Sigma to Trainium and Inferentia-powered instances.
Solution overview
The steps outlined below will be used to deploy the PixArt-Sigma model on AWS Trainium and run inference on it to generate high-quality images.

Step 1 – Pre-requisites and setup
Step 2 – Download and compile the PixArt-Sigma model for AWS Trainium
Step 3 – Deploy the model on AWS Trainium to generate images

Step 1 – Prerequisites and setup
To get started, you will need to set up a development environment on a trn1, trn2, or inf2 host. Complete the following steps:

Launch a trn1.32xlarge or trn2.48xlarge instance with a Neuron DLAMI. For instructions on how to get started, refer to Get Started with Neuron on Ubuntu 22 with Neuron Multi-Framework DLAMI.
Launch a Jupyter Notebook sever. For instructions to set up a Jupyter server, refer to the following user guide.
Clone the aws-neuron-samples GitHub repository:

git clone https://github.com/aws-neuron/aws-neuron-samples.git

Navigate to the hf_pretrained_pixart_sigma_1k_latency_optimized.ipynb notebook:

cd aws-neuron-samples/torch-neuronx/inference

The provided example script is designed to run on a Trn2 instance, but you can adapt it for Trn1 or Inf2 instances with minimal modifications. Specifically, within the notebook and in each of the component files under the neuron_pixart_sigma directory, you will find commented-out changes to accommodate Trn1 or Inf2 configurations.
Step 2 – Download and compile the PixArt-Sigma model for AWS Trainium
This section provides a step-by-step guide to compiling PixArt-Sigma for AWS Trainium.
Download the model
You will find a helper function in cache-hf-model.py in above mentioned GitHub repository that shows how to download the PixArt-Sigma model from Hugging Face. If you are using PixArt-Sigma in your own workload, and opt not to use the script included in this post, you can use the huggingface-cli to download the model instead.
The Neuron PixArt-Sigma implementation contains a few scripts and classes. The various files and scrips are broken down as follows:
├── compile_latency_optimized.sh # Full Model Compilation script for Latency Optimized
├── compile_throughput_optimized.sh # Full Model Compilation script for Throughput Optimized
├── hf_pretrained_pixart_sigma_1k_latency_optimized.ipynb # Notebook to run Latency Optimized Pixart-Sigma
├── hf_pretrained_pixart_sigma_1k_throughput_optimized.ipynb # Notebook to run Throughput Optimized Pixart-Sigma
├── neuron_pixart_sigma
│ ├── cache_hf_model.py # Model downloading Script
│ ├── compile_decoder.py # Text Encoder Compilation Script and Wrapper Class
│ ├── compile_text_encoder.py # Text Encoder Compilation Script and Wrapper Class
│ ├── compile_transformer_latency_optimized.py # Latency Optimized Transformer Compilation Script and Wrapper Class
│ ├── compile_transformer_throughput_optimized.py # Throughput Optimized Transformer Compilation Script and Wrapper Class
│ ├── neuron_commons.py # Base Classes and Attention Implementation
│ └── neuron_parallel_utils.py # Sharded Attention Implementation
└── requirements.txt
This notebook will help you to download the model, compile the individual component models, and invoke the generation pipeline to generate an image. Although the notebooks can be run as a standalone sample, the next few sections of this post will walk through the key implementation details within the component files and scripts to support running PixArt-Sigma on Neuron.

Sharding PixArt linear layers

For each component of PixArt (T5, Transformer, and VAE), the example uses Neuron specific wrapper classes. These wrapper classes serve two purposes. The first purpose is it allows us to trace the models for compilation:
class InferenceTextEncoderWrapper(nn.Module):
def __init__(self, dtype, t: T5EncoderModel, seqlen: int):
super().__init__()
self.dtype = dtype
self.device = t.device
self.t = t
def forward(self, text_input_ids, attention_mask=None):
return [self.t(text_input_ids, attention_mask)[‘last_hidden_state’].to(self.dtype)]

Please refer to the neuron_commons.py file for all wrapper modules and classes.
The second reason for using wrapper classes is to modify the attention implementation to run on Neuron. Because diffusion models like PixArt are typically compute-bound, you can improve performance by sharding the attention layer across multiple devices. To do this, you replace the linear layers with NeuronX Distributed’s RowParallelLinear and ColumnParallelLinear layers:
def shard_t5_self_attention(tp_degree: int, selfAttention: T5Attention):
orig_inner_dim = selfAttention.q.out_features
dim_head = orig_inner_dim // selfAttention.n_heads
original_nheads = selfAttention.n_heads
selfAttention.n_heads = selfAttention.n_heads // tp_degree
selfAttention.inner_dim = dim_head * selfAttention.n_heads
orig_q = selfAttention.q
selfAttention.q = ColumnParallelLinear(
selfAttention.q.in_features,
selfAttention.q.out_features,
bias=False,
gather_output=False)
selfAttention.q.weight.data = get_sharded_data(orig_q.weight.data, 0)
del(orig_q)
orig_k = selfAttention.k
selfAttention.k = ColumnParallelLinear(
selfAttention.k.in_features,
selfAttention.k.out_features,
bias=(selfAttention.k.bias is not None),
gather_output=False)
selfAttention.k.weight.data = get_sharded_data(orig_k.weight.data, 0)
del(orig_k)
orig_v = selfAttention.v
selfAttention.v = ColumnParallelLinear(
selfAttention.v.in_features,
selfAttention.v.out_features,
bias=(selfAttention.v.bias is not None),
gather_output=False)
selfAttention.v.weight.data = get_sharded_data(orig_v.weight.data, 0)
del(orig_v)
orig_out = selfAttention.o
selfAttention.o = RowParallelLinear(
selfAttention.o.in_features,
selfAttention.o.out_features,
bias=(selfAttention.o.bias is not None),
input_is_parallel=True)
selfAttention.o.weight.data = get_sharded_data(orig_out.weight.data, 1)
del(orig_out)
return selfAttention

Please refer to the neuron_parallel_utils.py file for more details on parallel attention.
Compile individual sub-models
The PixArt-Sigma model is composed of three components. Each component is compiled so the entire generation pipeline can run on Neuron:

Text encoder – A 4-billion-parameter encoder, which translates a human-readable prompt into an embedding. In the text encoder, the attention layers are sharded, along with the feed-forward layers, with tensor parallelism.
Denoising transformer model – A 700-million-parameter transformer, which iteratively denoises a latent (a numerical representation of a compressed image). In the transformer, the attention layers are sharded, along with the feed-forward layers, with tensor parallelism.
Decoder – A VAE decoder that converts our denoiser-generated latent to an output image. For the decoder, the model is deployed with data parallelism.

Now that the model definition is ready, you need to trace a model to run it on Trainium or Inferentia. You can see how to use the trace() function to compile the decoder component model for PixArt in the following code block:
compiled_decoder = torch_neuronx.trace(
decoder,
sample_inputs,
compiler_workdir=f”{compiler_workdir}/decoder”,
compiler_args=compiler_flags,
inline_weights_to_neff=False
)

Please refer to the compile_decoder.py file for more on how to instantiate and compile the decoder.
To run models with tensor parallelism, a technique used to split a tensor into chunks across multiple NeuronCores, you need to trace with a pre-specified tp_degree. This tp_degree specifies the number of NeuronCores to shard the model across. It then uses the parallel_model_trace API to compile the encoder and transformer component models for PixArt:
compiled_text_encoder = neuronx_distributed.trace.parallel_model_trace(
get_text_encoder_f,
sample_inputs,
compiler_workdir=f”{compiler_workdir}/text_encoder”,
compiler_args=compiler_flags,
tp_degree=tp_degree,
)

Please refer to the compile_text_encoder.py file for more details on tracing the encoder with tensor parallelism.
Lastly, you trace the transformer model with tensor parallelism:
compiled_transformer = neuronx_distributed.trace.parallel_model_trace(
get_transformer_model_f,
sample_inputs,
compiler_workdir=f”{compiler_workdir}/transformer”,
compiler_args=compiler_flags,
tp_degree=tp_degree,
inline_weights_to_neff=False,
)

Please refer to the compile_transformer_latency_optimized.py file for more details on tracing the transformer with tensor parallelism.
You will use the compile_latency_optimized.sh script to compile all three models as described in this post, so these functions will be run automatically when you run through the notebook.
Step 3 – Deploy the model on AWS Trainium to generate images
This section will walk us through the steps to run inference on PixArt-Sigma on AWS Trainium.
Create a diffusers pipeline object
The Hugging Face diffusers library is a library for pre-trained diffusion models, and includes model-specific pipelines that bundle the components (independently-trained models, schedulers, and processors) needed to run a diffusion model. The PixArtSigmaPipeline is specific to the PixArtSigma model, and is instantiated as follows:
pipe: PixArtSigmaPipeline = PixArtSigmaPipeline.from_pretrained(
“PixArt-alpha/PixArt-Sigma-XL-2-1024-MS”,
torch_dtype=torch.bfloat16,
local_files_only=True,
cache_dir=”pixart_sigma_hf_cache_dir_1024″)

Please refer to the hf_pretrained_pixart_sigma_1k_latency_optimized.ipynb notebook for details on pipeline execution.
Load compiled component models into the generation pipeline
After each component model has been compiled, load them into the overall generation pipeline for image generation. The VAE model is loaded with data parallelism, which allows us to parallelize image generation for batch size or multiple images per prompt. For more details, refer to the hf_pretrained_pixart_sigma_1k_latency_optimized.ipynb notebook.
vae_decoder_wrapper.model = torch_neuronx.DataParallel(
torch.jit.load(decoder_model_path), [0, 1, 2, 3], False
)

text_encoder_wrapper.t = neuronx_distributed.trace.parallel_model_load(
text_encoder_model_path
)

Finally, the loaded models are added to the generation pipeline:
pipe.text_encoder = text_encoder_wrapper
pipe.transformer = transformer_wrapper
pipe.vae.decoder = vae_decoder_wrapper
pipe.vae.post_quant_conv = vae_post_quant_conv_wrapper

Compose a prompt
Now that the model is ready, you can write a prompt to convey what kind of image you want generated. When creating a prompt, you should always be as specific as possible. You can use a positive prompt to convey what is wanted in your new image, including a subject, action, style, and location, and can use a negative prompt to indicate features that should be removed.
For example, you can use the following positive and negative prompts to generate a photo of an astronaut riding a horse on mars without mountains:
# Subject: astronaut
# Action: riding a horse
# Location: Mars
# Style: photo
prompt = “a photo of an astronaut riding a horse on mars”
negative_prompt = “mountains”

Feel free to edit the prompt in your notebook using prompt engineering to generate an image of your choosing.
Generate an image
To generate an image, you pass the prompt to the PixArt model pipeline, and then save the generated image for later reference:
# pipe: variable holding the Pixart generation pipeline with each of
# the compiled component models
images = pipe(
prompt=prompt,
negative_prompt=negative_prompt,
num_images_per_prompt=1,
height=1024, # number of pixels
width=1024, # number of pixels
num_inference_steps=25 # Number of passes through the denoising model
).images

for idx, img in enumerate(images):
img.save(f”image_{idx}.png”)

Cleanup
To avoid incurring additional costs, stop your EC2 instance using either the AWS Management Console or AWS Command Line Interface (AWS CLI).
Conclusion
In this post, we walked through how to deploy PixArt-Sigma, a state-of-the-art diffusion transformer, on Trainium instances. This post is the first in a series focused on running diffusion transformers for different generation tasks on Neuron. To learn more about running diffusion transformers models with Neuron, refer to Diffusion Transformers.

This post is the second part of the DeepSeek series focusing on model customization with Amazon SageMaker HyperPod recipes (or recipes for brevity). In Part 1, we demonstrated the performance and ease of fine-tuning DeepSeek-R1 distilled models using these recipes. In this post, we use the recipes to fine-tune the original DeepSeek-R1 671b parameter model. We demonstrate this through the step-by-step implementation of these recipes using both SageMaker training jobs and SageMaker HyperPod.
Business use case
After its public release, DeepSeek-R1 model, developed by DeepSeek AI, showed impressive results across multiple evaluation benchmarks. The model follows the Mixture of Experts (MoE) architecture and has 671 billion parameters. Traditionally, large models are well adapted for a wide spectrum of generalized tasks by the virtue of being trained on the huge amount of data. The DeepSeek-R1 model was trained on 14.8 trillion tokens. The original R1 model demonstrates strong few-shot or zero-shot learning capabilities, allowing it to generalize to new tasks and scenarios that weren’t part of its original training.
However, many customers prefer to either fine-tune or run continuous pre-training of these models to adapt it to their specific business applications or to optimize it for specific tasks. A financial organization might want to customize the model with their custom data to assist with their data processing tasks. Or a hospital network can fine-tune it with their patient records to act as a medical assistant for their doctors. Fine-tuning can also extend the model’s generalization ability. Customers can fine-tune it with a corpus of text in specific languages that aren’t fully represented in the original training data. For example, a model fine-tuned with an additional trillion tokens of Hindi language will be able to expand the same generalization capabilities to Hindi.
The decision on which model to fine-tune depends on the end application as well as the available dataset. Based on the volume of proprietary data, customers can decide to fine-tune the larger DeepSeek-R1 model instead of doing it for one of the distilled versions. In addition, the R1 models have their own set of guardrails. Customers might want to fine-tune to update those guardrails or expand on them.
Fine-tuning larger models like DeepSeek-R1 requires careful optimization to balance cost, deployment requirements, and performance effectiveness. To achieve optimal results, organizations must meticulously select an appropriate environment, determine the best hyperparameters, and implement efficient model sharding strategies.
Solution architecture
SageMaker HyperPod recipes effectively address these requirements by providing a carefully curated mix of distributed training techniques, optimizations, and configurations for state-of-the-art (SOTA) open source models. These recipes have undergone extensive benchmarking, testing, and validation to provide seamless integration with the SageMaker training and fine-tuning processes.
In this post, we explore solutions that demonstrate how to fine-tune the DeepSeek-R1 model using these recipes on either SageMaker HyperPod or SageMaker training jobs. Your choice between these services will depend on your specific requirements and preferences. If you require granular control over training infrastructure and extensive customization options, SageMaker HyperPod is the ideal choice. SageMaker training jobs, on the other hand, is tailored for organizations that want a fully managed experience for their training workflows. To learn more details about these service features, refer to Generative AI foundation model training on Amazon SageMaker.
The following diagram illustrates the solution architecture for training using SageMaker HyperPod. With HyperPod, users can begin the process by connecting to the login/head node of the Slurm cluster. Each step is run as a Slurm job and uses Amazon FSx for Lustre for storing model checkpoints. For DeepSeek-R1, the process consists of the following steps:

Download the DeepSeek-R1 model and convert weights from FP8 to BF16 format
Load the model into memory and perform fine-tuning using Quantized Low-Rank Adaptation (QLoRA)
Merge QLoRA adapters with the base model
Convert and load the model for batch evaluation

The following diagram illustrates the solution architecture for SageMaker training jobs. You can execute each step in the training pipeline by initiating the process through the SageMaker control plane using APIs, AWS Command Line Interface (AWS CLI), or the SageMaker ModelTrainer SDK. In response, SageMaker launches training jobs with the requested number and type of compute instances to run specific tasks. For DeepSeek-R1, the process consists of three main steps:

Download and convert R1 to BF16 datatype format
Load the model into memory and perform fine-tuning
Consolidate and load the checkpoints into memory, then run inference and metrics to evaluate performance improvements

Prerequisites
Complete the following prerequisites before running the DeepSeek-R1 671B model fine-tuning notebook:

Make the following quota increase requests for SageMaker. You need to request a minimum of two ml.p5.48xlarge instances (with 8 x NVIDIA H100 GPUs) ranging to a maximum of four ml.p5.48xlarge instances (depending on time-to-train and cost-to-train trade-offs for your use case). On the Service Quotas console, request the following SageMaker quotas. It can take up to 24 hours for the quota increase to be approved:

P5 instances (ml.p5.48xlarge) for training job usage: 2–4
P5 instances (ml.p5.48xlarge) for HyperPod clusters (ml.p5.48xlarge for cluster usage): 2–4

If you choose to use HyperPod clusters to run your training, set up a HyperPod Slurm cluster, referring to Amazon SageMaker HyperPod Developer Guide. Alternatively, you can also use the AWS CloudFormation template provided in the Own Account workshop and follow the instructions to set up a cluster and a development environment to access and submit jobs to the cluster.
(Optional) If you choose to use SageMaker training jobs, you can create an Amazon SageMaker Studio domain (refer to Use quick setup for Amazon SageMaker AI) to access Jupyter notebooks with the preceding role (You can use JupyterLab in your local setup too).

Create an AWS Identity and Access Management (IAM) role with managed policies AmazonSageMakerFullAccess, AmazonFSxFullAccess, and AmazonS3FullAccess to give the necessary access to SageMaker to run the examples.

Clone the GitHub repository with the assets for this deployment. This repository consists of a notebook that references training assets:

git clone https://github.com/aws-samples/sagemaker-distributed-training-workshop.git
cd 18_sagemaker_training_recipes/ft_deepseek_r1_qlora

Solution walkthrough
To perform the solution, follow the steps in the next sections.
Technical considerations
The default weights provided by the DeepSeek team on their official R1 repository are of type FP8. However, we chose to disable FP8 in our recipes because we empirically found that training with BF16 enhances generalization across diverse datasets with minimal changes to the recipe hyperparameters. Therefore, to achieve stable fine-tuning for a model of 671b parameter size, we recommend first converting the model from FP8 to BF16 using the fp8_cast_bf16.py command-line script provided by DeepSeek. Executing this script will copy over the converted BF16 weights in Safetensor format to the specified output directory. Remember to copy over the model’s config.yaml to the output directory so the weights are loaded accurately. These steps are encapsulated in a prologue script and are documented step-by-step under the Fine-tuning section.
Customers can use a sequence length of 8K for training, as tested on a p5.48xlarge instance, each equipped with eight NVIDIA H100 GPUs. You can also choose a smaller sequence length if needed. Training with a sequence length greater than 8K might lead to out-of-memory issues with GPUs. Also, converting model weights from FP8 to BF16 requires a p5.48xlarge instance, which is also recommended for training due to the model’s high host memory requirements during initialization.
Customers must upgrade their transformers version to transformers==4.48.2 to run the training.
Fine-tuning
Run the finetune_deepseek_r1_671_qlora.ipynb notebook to fine-tune the DeepSeek-R1 model using QLoRA on SageMaker.
Prepare the dataset
This section covers loading the FreedomIntelligence/medical-o1-reasoning-SFT dataset, tokenizing and chunking the dataset, and configuring the data channels for SageMaker training on Amazon Simple Storage Service (Amazon S3). Complete the following steps:

Format the dataset by applying the prompt format for DeepSeek-R1:

def generate_prompt(data_point):
full_prompt = f”””
Below is an instruction that describes a task, paired with an input
that provides further context.
Write a response that appropriately completes the request.
Before answering, think carefully about the question and create a step-by-step chain of thoughts to ensure a logical and accurate response.

### Instruction:
You are a medical expert with advanced knowledge in clinical reasoning, diagnostics, and treatment planning.
Please answer the following medical question.

### Question:
{data_point[“Question”]}

### Response:
{data_point[“Complex_CoT”]}

“””
return {“prompt”: full_prompt.strip()}

Load the FreedomIntelligence/medical-o1-reasoning-SFT dataset and split it into training and validation datasets:

# Load dataset from the hub
train_set = load_dataset(dataset_name, ‘en’, split=”train[5%:]”)
test_set = load_dataset(dataset_name, ‘en’, split=”train[:5%]”)

…

train_dataset = train_set.map(
generate_and_tokenize_prompt,
remove_columns=columns_to_remove,
batched=False
)

test_dataset = test_set.map(
generate_and_tokenize_prompt,
remove_columns=columns_to_remove,
batched=False
)

Load the DeepSeek-R1 tokenizer from the Hugging Face Transformers library and generate tokens for the train and validation datasets. We use the original sequence length of 8K:

model_id = “deepseek-ai/DeepSeek-R1”
max_seq_length=8096

# Initialize a tokenizer by loading a pre-trained tokenizer configuration, using the fast tokenizer implementation if available.
tokenizer = AutoTokenizer.from_pretrained(model_id, use_fast=True)

…

train_dataset = train_dataset.map(tokenize, remove_columns=[“prompt”])
test_dataset = test_dataset.map(tokenize, remove_columns=[“prompt”])

Prepare the training and validation datasets for SageMaker training by saving them as arrow files, required by SageMaker HyperPod recipes, and constructing the S3 paths where these files will be uploaded. This dataset will be used in both SageMaker training jobs and SageMaker HyperPod examples:

train_dataset_s3_path = f”s3://{bucket_name}/{input_path}/train”
val_dataset_s3_path = f”s3://{bucket_name}/{input_path}/test”

train_dataset.save_to_disk(train_dataset_s3_path)
val_dataset.save_to_disk(val_dataset_s3_path)

The next section describes how to run a fine-tuning example with SageMaker training jobs.
Option A: Fine-tune using SageMaker training jobs
Follow these high-level steps:

Download DeepSeek-R1 to the FSx for Lustre mounted directory
Convert DeepSeek-R1 from FP8 to BF16
Fine-tune the DeepSeek-R1 model
Merge the trained adapter with the base model

Define a utility function to create the ModelTrainer class for every step of the SageMaker training jobs pipeline:

# Creates and executes a model training job using SageMaker
def create_model_trainer(
use_recipes: bool,
compute: dict,
network: dict,
data_channel: dict,
action: str,
hyperparameters: dict ={},
source_code: str=None,
training_recipe: str=None,
recipe_overrides: str=None,
image_uri: str=None
) -> ModelTrainer:

…

Download DeepSeek-R1 to the FSx for Lustre mounted directory
Follow these steps:

Select the instance type, Amazon FSx data channel, network configuration for the training job, and source code, then define the ModelTrainer class to run the training job on the ml.c5.18xlarge instance to download DeepSeek-R1 from the Hugging Face DeepSeek-R1 hub:

# Create compute instance
compute = ComputeCreator.create(
instance_type=”ml.c5.18xlarge”,
instance_count=1
)

# Create FSx data channel
data_channel = FSxDataChannelCreator.create_channel(
directory_path=fsx_mount_point
)

# Create network configuration
network = NetworkConfigCreator.create_network_config(network_config)

# Set up source code configuration
source_code = SourceCode(
source_dir=”scripts”,
entry_script=”download.py”
)
…

# Create model trainer
model_trainer = create_model_trainer(
compute=compute,
network=network,
data_channel=data_channel,
action=”download”,
source_code=source_code
…
)

Initiate the training calling train function of the ModelTrainer class:

model_trainer.train(input_data_config=[data_channel], wait=True)

Convert DeepSeek R1 from FP8 to BF16
Use ModelTrainer to convert the DeepSeek-R1 downloaded model weights from FP8 to BF16 format for optimal PEFT training. We use script convert.sh to run the execution using the ml.c5.18xlarge instance.
Use SageMaker training warm pool configuration to retain and reuse provisioned infrastructure after the completion of a model download training job in the previous step:

# Define constants
FSX_MODELDIR_BF16 = “deepseek-r1-bf16″
FSX_DIR_PATH = f”{fsx_mount_point}/{fsx_dir_basemodel}”

# Create compute instance
compute = ComputeCreator.create(
instance_type=”ml.p5.48xlarge”,
instance_count=1
)

…

# Set up source code configuration
source_code = SourceCode(
source_dir=”scripts”,
entry_script=”convert.sh”
)

…
# Create model trainer for conversion
model_trainer = create_model_trainer(
..
action=”convert”,
…
)

Fine-tune the DeepSeek-R1 model
The next phase involves fine-tuning the DeepSeek-R1 model using two ml.p5.48xlarge instances, using distributed training. You implement this through the SageMaker recipe hf_deepseek_r1_671b_seq8k_gpu_qlora, which incorporates the QLoRA methodology. QLoRA makes the large language model (LLM) trainable on limited compute by quantizing the base model to 4-bit precision while using small, trainable low-rank adapters for fine-tuning, dramatically reducing memory requirements without sacrificing model quality:

# Create compute configuration with P5 instances
compute = ComputeCreator.create(
instance_type=”ml.p5.48xlarge”,
instance_count=2
)

…

# Create model trainer for fine-tuning
model_trainer = create_model_trainer(
use_recipes=True,
…
action=”finetune”,
training_recipe=’fine-tuning/deepseek/hf_deepseek_r1_671b_seq8k_gpu_qlora’,
recipe_overrides=recipe_overrides
)

Initiate the training job to fine-tune the model. SageMaker training jobs will provision two P5 instances, orchestrate the SageMaker model parallel container smdistributed-modelparallel:2.4.1-gpu-py311-cu121, and execute the recipe to fine-tune DeepSeek-R1 with the QLoRA strategy on an ephemeral cluster:

model_trainer.train (input_data_config=[data_channel], wait=True)

Merge the trained adapter with the base model
Merge the trained adapters with the base model so it can be used for inference:

# Create compute configuration with P5 instance
compute = ComputeCreator.create(
instance_type=”ml.p5.48xlarge”,
instance_count=1
)

# Configure source code location and entry point
source_code = SourceCode(
source_dir=”scripts”,
entry_script=”cli-inference.sh”
)
…

# Create model trainer for adapter merging
model_trainer = create_model_trainer(
use_recipes=False,
…
action=”mergeadapter”,
source_code=source_code,
)

The next section shows how you can run similar steps on HyperPod to run your generative AI workloads.
Option B: Fine-tune using SageMaker HyperPod with Slurm
To fine-tune the model using HyperPod, make sure that your cluster is up and ready by following the prerequisites mentioned earlier. To access the login/head node of the HyperPod Slurm cluster from your development environment, follow the login instructions at SSH into Cluster in the workshop.
Alternatively, you can also use AWS Systems Manager and run a command such as the following to start the session. You can find the cluster ID, instance group name, and instance ID on the Amazon SageMaker console.

aws ssm start-session –target sagemaker-cluster:[cluster-id]_[instance-group-name]-[instance-id] –region region_name

When you’re in the cluster’s login/head node, run the following commands to set up the environment. Run sudo su – ubuntu to run the remaining commands as the root user, unless you have a specific user ID to access the cluster and your POSIX user is created through a lifecycle script on the cluster. Refer to the multi-user setup for more details.

# create a virtual environment
python3 -m venv ${PWD}/venv
source venv/bin/activate

# clone the recipes repository and set up the environment
git clone –recursive https://github.com/aws/sagemaker-hyperpod-recipes.git
cd sagemaker-hyperpod-recipes
pip3 install -r requirements.txt

Create a squash file using Enroot to run the job on the cluster. Enroot runtime offers GPU acceleration, rootless container support, and seamless integration with HPC environments, making it ideal for running workflows securely.

# create a squash file using Enroot
REGION=<region>
IMAGE=”658645717510.dkr.ecr.${REGION}.amazonaws.com/smdistributed-modelparallel:2.4.1-gpu-py311-cu121″
aws ecr get-login-password –region “${REGION}” | docker login –username AWS –password-stdin 658645717510.dkr.ecr.${REGION}.amazonaws.com
enroot import -o $PWD/smdistributed-modelparallel.sqsh dockerd://${IMAGE}

After you’ve created the squash file, update the recipes_collection/config.yaml file with the absolute path to the squash file (created in the preceding step), and update the instance_type if needed. The final config file should have the following parameters:

…

cluster_type: slurm
…

instance_type: p5.48xlarge
…

container: /fsx/<path-to-smdistributed-modelparallel>.sqsh
…

Also update the file recipes_collection/cluster/slurm.yaml to add container_mounts pointing to the FSx for Lustre file system used in your cluster.
Follow these high-level steps to set up, fine-tune, and evaluate the model using HyperPod recipes:

Download the model and convert weights to BF16
Fine-tune the model using QLoRA
Merge the trained model adapter
Evaluate the fine-tuned model

Download the model and convert weights to BF16
Download the DeepSeek-R1 model from the HuggingFace hub and convert the model weights from FP8 to BF16. You need to convert this to use QLoRA for fine-tuning. Copy and execute the following bash script:

#!/bin/bash
start=$(date +%s)
# install git lfs and download the model from huggingface
sudo apt-get install git-lfs
GIT_LFS_SKIP_SMUDGE=1 && git clone https://huggingface.co/deepseek-ai/DeepSeek-R1
&& cd DeepSeek-R1 && git config lfs.concurrenttransfers nproc &&  git lfs pull
end=$(date +%s)
echo “Time taken to download model: $((end – start)) seconds”
start=$(date +%s)
#convert the model weights from fp8 to bf16
source venv/bin/activate
git clone https://github.com/deepseek-ai/DeepSeek-V3.git
cd DeepSeek-V3/inference && pip install -r requirements.txt &&
wget https://github.com/aws/sagemaker-hyperpod-training-adapter-for-nemo/blob/main/src/hyperpod_nemo_adapter/scripts/fp8_cast_bf16.py &&
python fp8_cast_bf16.py –input-fp8-hf-path ./DeepSeek-R1 –output-bf16-hf-path ./DeepSeek-R1-bf16

end=$(date +%s)
echo “Time taken to convert model to BF16: $((end – start)) seconds”

Fine-tune the model using QLoRA
Download the prepared dataset that you uploaded to Amazon S3 into your FSx for Lustre volume attached to the cluster.

Enter the following commands to download the files from Amazon S3:

aws s3 cp s3://{bucket_name}/{input_path}/train /fsx/ubuntu/deepseek/data/train –recursive
aws s3 cp s3://{bucket_name}/{input_path}/test /fsx/ubuntu/deepseek/data/test –recursive

Update the launcher script to fine-tune the DeepSeek-R1 671B model. The launcher scripts serve as convenient wrappers for executing the training script, main.py file, simplifying the process of fine-tuning and parameter adjustment. For fine-tuning the DeepSeek R1 671B model, you can find the specific script at:

launcher_scripts/deepseek/run_hf_deepseek_r1_671b_seq8k_gpu_qlora.sh

Before running the script, you need to modify the location of the training and validation files, update the HuggingFace model ID, and optionally the access token for private models and datasets. The script should look like the following (update recipes.trainer.num_nodes if you’re using a multi-node cluster):

#!/bin/bash

# Original Copyright (c), NVIDIA CORPORATION. Modifications © Amazon.com

#Users should setup their cluster type in /recipes_collection/config.yaml

SAGEMAKER_TRAINING_LAUNCHER_DIR=${SAGEMAKER_TRAINING_LAUNCHER_DIR:-“$(pwd)”}

HF_MODEL_NAME_OR_PATH=”/fsx/ubuntu/deepseek/DeepSeek-R1-bf16″ # Path to the BF16 converted model

TRAIN_DIR=”/fsx/ubuntu/deepseek/data/train” # Location of training dataset
VAL_DIR=”/fsx/ubuntu/deepseek/data/train/” # Location of validation dataset

EXP_DIR=”/fsx/ubuntu/deepseek/checkpoints” # Location to save experiment info including logging, checkpoints, etc.

HYDRA_FULL_ERROR=1 python3 “${SAGEMAKER_TRAINING_LAUNCHER_DIR}/main.py”
recipes=fine-tuning/deepseek/hf_deepseek_r1_671b_seq8k_gpu_qlora
base_results_dir=”${SAGEMAKER_TRAINING_LAUNCHER_DIR}/results”
recipes.run.name=”hf-deepseek-r1-671b-seq8k-gpu-qlora”
recipes.exp_manager.exp_dir=”$EXP_DIR”
recipes.trainer.num_nodes=2

recipes.model.data.train_dir=”$TRAIN_DIR”
recipes.model.data.val_dir=”$VAL_DIR”
recipes.model.hf_model_name_or_path=”$HF_MODEL_NAME_OR_PATH”

You can view the recipe for this fine-tuning task under recipes_collection/recipes/fine-tuning/deepseek/hf_deepseek_r1_671b_seq8k_gpu_qlora.yaml and override additional parameters as needed.

Submit the job by running the launcher script:

bash launcher_scripts/deepseek/run_hf_deepseek_r1_671b_seq8k_gpu_qlora.sh

Monitor the job using Slurm commands such as squeue and scontrol show to view the status of the job and the corresponding logs. The logs can be found in the results folder in the launch directory. When the job is complete, the model adapters are stored in the EXP_DIR that you defined in the launch. The structure of the directory should look like this:

ls -R
.:.:
checkpoints experiment result.json

./checkpoints:
peft_sharded

./checkpoints/peft_sharded:
step_50

./checkpoints/peft_sharded/step_50:
README.md adapter_config.json adapter_model.safetensors tp0_ep0

You can see the trained adapter weights are stored as part of the checkpointing under ./checkpoints/peft_sharded/step_N. We will later use this to merge with the base model.
Merge the trained model adapter
Follow these steps:

Run a job using the smdistributed-modelparallel enroot image to merge the adapter with the base model.

Evaluate the fine-tuned model
Use the basic testing scripts provided by DeekSeek to deploy the merged model.

Start by cloning their repo:

git clone https://github.com/deepseek-ai/DeepSeek-V3.git

cd DeepSeek-V3/inference
pip install -r requirements.txt

You need to convert the merged model to a specific format for running inference. In this case, you need 4*P5 instances to deploy the model because the merged model is in BF16. Enter the following command to convert the model:

python convert.py –hf-ckpt-path /fsx/ubuntu/deepseek/DeepSeek-V3-Base/
–save-path /fsx/ubuntu/deepseek/DeepSeek-V3-Demo –n-experts 256
–model-parallel 32

When the conversion is complete, use the following sbatch script to run the batch inference, making the following adjustments:

Update the ckpt-path to the converted model path from the previous step.
Create a new prompts.txt file with each line containing a prompt. The job will use the prompts from this file and generate output.

Cleanup
To clean up your resources to avoid incurring more charges, follow these steps:

Delete any unused SageMaker Studio resources.
(Optional) Delete the SageMaker Studio domain.
Verify that your training job isn’t running anymore. To do so, on your SageMaker console, choose Training and check Training jobs.
If you created a HyperPod cluster, delete the cluster to stop incurring costs. If you created the networking stack from the HyperPod workshop, delete the stack as well to clean up the virtual private cloud (VPC) resources and the FSx for Lustre volume.

According to a Gartner survey in 2024, 58% of finance functions have adopted generative AI, marking a significant rise in adoption. Among these, four primary use cases have emerged as especially prominent: intelligent process automation, anomaly detection, analytics, and operational assistance.
In this post, we show you how Amazon Q Business can help augment your generative AI needs in all the abovementioned use cases and more by answering questions, providing summaries, generating content, and securely completing tasks based on data and information in your enterprise systems.
Amazon Q Business is a generative AI–powered conversational assistant that helps organizations make better use of their enterprise data. Traditionally, businesses face a challenge. Their information is split between two types of data: unstructured data (such as PDFs, HTML pages, and documents) and structured data (such as databases, data lakes, and real-time reports). Different types of data typically require different tools to access them. Documents require standard search tools, and structured data needs business intelligence (BI) tools such as Amazon QuickSight.
To bridge this gap, Amazon Q Business provides a comprehensive solution that addresses the longstanding challenge of siloed enterprise data. Organizations often struggle with fragmented information split between unstructured content—such as PDFs, HTML pages, and documents—and structured data stored in databases, data lakes, or real-time reports. Traditionally, these data types require separate tools: standard search functionalities for documents, and business intelligence (BI) tools like Amazon QuickSight for structured content. Amazon Q Business excels at handling unstructured data through more than 40 prebuilt connectors that integrate with platforms like Confluence, SharePoint, and Amazon Simple Storage Service (Amazon S3)—enabling businesses to consolidate and interact with enterprise knowledge through a single, conversational interface. Amazon QuickSight is a comprehensive Business Intelligence (BI) environment that offers a range of advanced features for data analysis and visualization. It combines interactive dashboards, natural language query capabilities, pixel-perfect reporting, machine learning (ML)–driven insights, and scalable embedded analytics in a single, unified service.
On December 3, 2024, Amazon Q Business announced the launch of its integration with QuickSight. With this integration, structured data sources can now be connected to Amazon Q Business applications, enabling a unified conversational experience for end users. QuickSight integration offers an extensive set of over 20 structured data source connectors, including Amazon S3, Amazon Redshift, Amazon Relational Database (Amazon RDS) for PostgreSQL, Amazon RDS for MySQL, and Amazon RDS for Oracle. This integration enables Amazon Q Business assistants to expand the conversational scope to cover a broader range of enterprise knowledge sources.
For end users, answers are returned in real time from your structured sources and combined with other relevant information found in unstructured repositories. Amazon Q Business uses the analytics and advanced visualization engine in QuickSight to generate accurate answers from structured sources.
Solution overview
In this post, we take a common scenario where a FinTech organization called AnyCompany  has financial analysts who spend 15–20 hours per week manually aggregating data from multiple sources (such as portfolio statements, industry reports, earnings calls, and financial news) to derive client portfolio insights and generate recommendations. This manual process can lead to delayed decision-making, inconsistent analysis, and missed investment opportunities.
For this use case, we show you how to build a generative AI–powered financial research assistant using Amazon Q Business and QuickSight that automatically processes both structured data such as stock prices and trend data and unstructured data such as industry insights from news and quarterly statements. Advisors can use the assistant to instantly generate portfolio visualizations, risk assessments, and actionable recommendations through straightforward natural language queries, reducing analysis time from hours to minutes while maintaining consistent, data-driven investment decisions.
This solution uses both unstructured and structured data. For the unstructured data, it uses publicly available annual financial reports filed with the Securities and Exchange Commission (SEC) for the leading technology companies in the S&P 500 index. The structured data comes from stock price trend information obtained through the Alpha Vantage API. This solution uses Amazon Q Business, a generative AI conversational assistant. With the integration of QuickSight, we can build a financial assistant that can summarize insights, answer industry data–related questions, and generate charts and visuals from both structured and unstructured data.
The following figure shows how Amazon Q Business can use both unstructured and structured data sources to answer questions.

Prerequisites
To perform the solution in this walkthrough, you need to have the following resources:

An active AWS account to access Amazon Q Business and QuickSight features.
AWS IAM Identity Center must be configured in your preferred Region. For this walkthrough, we used US East (N. Virginia). For more information, refer to Configure Amazon Q Business with AWS IAM Identity Center trusted identity propagation.
The necessary users and groups for Amazon Q Business and QuickSight access with at least one Amazon Q Business Pro user with administrative privileges. Users or groups can also be sourced from an identity provider (IdP) integrated with IAM Identity Center.
An IAM Identity Center group designated for QuickSight Admin Pro role for users who will manage and configure QuickSight.
QuickSight must be configured in the same AWS account and Region as Amazon Q Business.
If a QuickSight account exists, it needs to be in the same AWS account and AWS Region as Amazon Q Business, and it needs to be configured with IAM Identity Center.
Ability to upload data using .csv or .xls files. An alternative is using an accessible database that QuickSight can connect to. The database must have proper permissions for table creation and data insertion.
Sample structured and unstructured data ready for import.

These components help to verify the proper functionality of the Amazon Q Business and QuickSight integration while maintaining secure access and data management capabilities.
Considerations
Amazon QuickSight and Amazon Q Business must exist in the same AWS account. Cross account calls aren’t supported at the time of writing this blog.
Amazon QuickSight and Amazon Q Business accounts must exist in the same AWS Region. Cross-Region calls aren’t supported at the time of writing this blog.
Amazon QuickSight and Amazon Q Business accounts that are integrated need to use the same identity methods.
IAM Identity Center setup is required for accessing AWS managed applications such as Amazon Q Business and helps in streamlining access for users.
Create users and groups in IAM Identity Center
To create users:

On the IAM Identity Center console, if you haven’t enabled IAM Identity Center, choose Enable. If there’s a pop-up, choose how you want to enable IAM Identity Center. For this walkthrough, select Enable with AWS Organizations and choose Continue.
On the IAM Identity Center dashboard, in the navigation pane, choose Users.
Choose Add user.
Enter the user details for John-Doe, as shown in the following screenshot:

Username: john_doe_admin
Email address: john_doe_admin@gmail.com. Use or create a real email address for each user to use in a later step.
First name: John
Last name: Doe
Display name: John Doe

Skip the optional fields and choose Next to create the user.
On the Add user to groups page, choose Next and then choose Add user. Follow the same steps to create other users for your Amazon Q Business application.
Similarly, create user groups like Admin, User, Author, Author_Pro for Amazon Q Business and QuickSight, as shown in the  following screenshot. Add the appropriate users into your user groups.

Create an Amazon Q Business application
To use this feature, you need to have an Amazon Q Business application. If you don’t have an existing application, follow the steps in Discover insights from Amazon S3 with Amazon Q S3 connector to create a Amazon Q Business application with an Amazon S3 data source. Upload the unstructured document(s) to Amazon S3 and sync the data source. The steps outlined below are required to create the Amazon Q Business application and are detailed in the above referenced blog post.

This image is a screenshot of the setup page for the Amazon Q Business application.
In this step, you create an Amazon Q Business application that powers the conversation web experience:

On the Amazon Q Business console, in the Region list, choose US East (N. Virginia).
On the Getting started page, select Enable identity-aware sessions. When it’s enabled, a notification that Amazon Q is connected to IAM Identity Center should be displayed. Choose Subscribe in Q Business.
On the Amazon Q Business console, choose Get started.
On the Applications page, choose Create application. On the Create application page, enter Application name and leave everything else with default values.
Choose Create, as shown in the following screenshot.
Navigate to your data sources and select Add an index, as shown in the following screenshot. We named our index Yearly-Financial-Statements.

The index creation process may take a few minutes to complete.

Meanwhile, create an S3 bucket and add the PDF files. The following images illustrate the S3 bucket creation process. We followed the same steps outlined in the blog post Discover insights from Amazon S3 with Amazon Q S3 connector, and the screenshots below reflect that process.

The following screenshot shows the PDF files we added to our S3 bucket. We added the PDF files of the yearly filings of the top 12 tech companies obtained from the SEC filing website.

After you’ve added your data to the S3 bucket, go back to the Amazon Q Business application named Market-Bot. Select Add Data Sources and choose S3, and complete the configuration steps. This process is illustrated in the screenshot below.

As part of the configuration, make sure to set the Sync mode to “New, modified, or deleted content sync” and the Sync run schedule to “Run On-Demand.”
After adding the data sources, choose Sync now to initiate the synchronization process, as shown in the following screenshot.

Create a QuickSight account and topic
You can skip this section if you already have an existing QuickSight account. To create a QuickSight account, complete the following steps. Query structured data from Amazon Q Business using Amazon QuickSight provides more in-depth steps you can follow to set up the QuickSight account.

On the Amazon Q Business console, in the navigation pane of your application, choose Amazon QuickSight.
Choose Create QuickSight account, as shown in the following screenshot.
Under QuickSight account information, enter your account name and an email for account notifications.
Under Assign QuickSight Admin Pro users, choose the IAM Identity Center group you created as a prerequisite. The following screenshot shows Admin has been selected. A user becomes a QuickSight Admin by being added to an IAM Identity Center group mapped to the QuickSight Admin Pro role during integration setup. (The admin must configure datasets, topics, and permissions within QuickSight for proper functionality of Amazon Q Business features.)
Choose Next.
Under Service access, select Create and use a new service role.
Choose Authorize, as shown in the following screenshot.

This will create a QuickSight account, assign the IAM Identity Center group as QuickSight Admin Pro, and authorize Amazon Q Business to access QuickSight.
You can now proceed to the next section to prepare your data.
Configure an existing QuickSight account
You can skip this section if you followed the previous steps and created a new QuickSight account.
If your current QuickSight account isn’t on IAM Identity Center, consider using a different AWS account without a QuickSight subscription to test this feature. From that account, you create an Amazon Q Business application on IAM Identity Center and go through the QuickSight integration setup on the Amazon Q Business console that will create the QuickSight account for you in IAM Identity Center.
Add data in QuickSight
In this section, you create an Amazon S3 data source. You can instead create a data source from the database of your choice or perform a direct upload of .csv files and connect to it. Refer to Creating a dataset from a database for more details.
To configure your data, complete the following steps:

Sign in to your QuickSight account with the admin credentials. When you sign in as the admin, you have access to both the Amazon Q Business and QuickSight application.
Select the QuickSight application to add your data to the QuickSight index.
On the QuickSight console, in the navigation pane, choose Datasets.
Under Create a Dataset, select Upload a file, as shown in the following screenshot.

We are uploading a CSV file containing stock price data for the top 10 S&P technology companies, as illustrated in the image below.

Generate topics from your dataset and to do this, select your dataset, click the Topics tab in the navigation menu on the left, and then choose Create new topic.

Creating a topic from a dataset in Amazon QuickSight enables natural language exploration (such as Q&A) and optimizes data for AI-driven insights. Topics act as structured collections of datasets tailored for Amazon Q, giving business users the flexibility to ask questions in plain language (for example, “Show sales by region last quarter”). Without a topic, Amazon Q can’t interpret unstructured queries or map them to relevant data fields. For more information, refer to Working with Amazon QuickSight Q topics.

Integrate Amazon Q Business with QuickSight
We must also enable access for QuickSight to use Q Business. The following screenshots detail the configuration steps.

Click the user profile icon in the top-right corner of the QuickSight console, then choose Manage QuickSight.
Under Security and permissions, give access to Amazon Q Business application by selecting the Amazon Q Business application you created.
Open your Amazon Q Business application and in the navigation pane, choose Amazon QuickSight. To enable your application to access QuickSight topic data, choose Authorize Amazon Q Business.
You should now be able to observe the datasets and topics available to Amazon Q for answering queries using your Amazon Q Business application.

We have successfully established integration between Amazon Q Business and QuickSight, enabling us to begin interacting with the Q Business application through the web experience interface.
Query your Amazon Q Business application
To start chatting with Amazon Q Business, complete the following steps:

On the Amazon Q Business console, choose your Amazon Q Business application.
Choose the link under the deployed URL.

The examples below demonstrate user interactions with Amazon Q Business through its integration with Amazon QuickSight. Each example includes the user’s query and Q Business’s corresponding response, showcasing the functionality and capabilities of this integration.

In this tutorial, we will learn how to deploy a fully functional Model Context Protocol (MCP) server using smithery as the configuration framework and VeryaX as the runtime orchestrator. We’ll walk through installing and configuring smithery to define your MCP endpoints, then leverage VeryaX to spin up and manage the server processes. Finally, we’ll integrate Firecrawl, an efficient document-crawling agent, by directly connecting it through the VeryaX-managed MCP server from the Claude Desktop client. By the end, we will have a streamlined pipeline for contextual AI workflows, with Firecrawl pushing content into our MCP-powered Claude environment in real time.

Step 01: Register on the VeryaX page and get access to setting up the required tools for the MCP server.

Step 02: Register on the FireCrawl page and access the API key.

Step 03: Go to the VeryaX dashboard and set up the Firecrawl MCP. Enter the Firecrawl API key from the previous step and paste it here.

Step 04: Now, configure the different Firecrawl configurations and save the configuration.

Step 05: Here, we can see the connected MCPs. The Firecrawl has been connected, and we can add more connections of different sorts if we want, following the same steps.

Step 06: In this part, configure the Smithery AI API key and copy it to use in the VeryaX desktop setup.

Step 07: Similar to Smithery AI, get the VeryaX API key from their site. With these two API keys handy, we will now configure our VeryaX MCP using the terminal.

Step 08: Now, let’s set up the VeryaX configuration on our desktop. Use the below command to add VeryaX to Claude’s desktop:

Copy CodeCopiedUse a different Browsernpx -y @smithery/cli@latest install @VeyraX/veyrax-mcp –client claude

Step 09: After successfully executing the above command in the terminal, provide the Smithery AI and VeryaX API keys when prompted. As in previous steps, we already have the API keys.

Step 10: Close the Claude desktop and restart it. Go to the settings and then developer, we will now have the VeryaX MCP configured and running.

Step 11: Check for the tools connected to VeryaX, and we can find the firecrawl there, as we have configured our VeryaX MCP for it.

Step 12: Finally, invoke the firecrawl and get some scrapping done through this easy-to-use setup and directly accessible firecrawl tools through Claude Desktop.

In conclusion, following these steps, we now have an MCP server defined with Smithery, orchestrated by VeryaX, and communicating seamlessly with Firecrawl from Claude Desktop. This setup standardizes how our AI agents exchange context and simplifies scaling and maintenance thanks to Smithery’s declarative configs and VeryaX’s robust runtime management. From here, we can extend our MCP server with additional tool plugins, customize routing rules in Smithery, or experiment with advanced Firecrawl crawlers to enrich our Claude-based applications with fresh, structured data.

Generative AI tools have transformed how we work, create, and process information. At Amazon Web Services (AWS), security is our top priority. Therefore, Amazon Bedrock provides comprehensive security controls and best practices to help protect your applications and data. In this post, we explore the security measures and practical strategies provided by Amazon Bedrock Agents to safeguard your AI interactions against indirect prompt injections, making sure that your applications remain both secure and reliable.
What are indirect prompt injections?
Unlike direct prompt injections that explicitly attempt to manipulate an AI system’s behavior by sending malicious prompts, indirect prompt injections are far more challenging to detect. Indirect prompt injections occur when malicious actors embed hidden instructions or malicious prompts within seemingly innocent external content such as documents, emails, or websites that your AI system processes. When an unsuspecting user asks their AI assistant or Amazon Bedrock Agents to summarize that infected content, the hidden instructions can hijack the AI, potentially leading to data exfiltration, misinformation, or bypassing other security controls. As organizations increasingly integrate generative AI agents into critical workflows, understanding and mitigating indirect prompt injections has become essential for maintaining security and trust in AI systems, especially when using tools such as Amazon Bedrock for enterprise applications.
Understanding indirect prompt injection and remediation challenges
Prompt injection derives its name from SQL injection because both exploit the same fundamental root cause: concatenation of trusted application code with untrusted user or exploitation input. Indirect prompt injection occurs when a large language model (LLM) processes and combines untrusted input from external sources controlled by a bad actor or trusted internal sources that have been compromised. These sources often include sources such as websites, documents, and emails. When a user submits a query, the LLM retrieves relevant content from these sources. This can happen either through a direct API call or by using data sources like a Retrieval Augmented Generation (RAG) system. During the model inference phase, the application augments the retrieved content with the system prompt to generate a response.
When successful, malicious prompts embedded within the external sources can potentially hijack the conversation context, leading to serious security risks, including the following:

System manipulation – Triggering unauthorized workflows or actions
Unauthorized data exfiltration – Extracting sensitive information, such as unauthorized user information, system prompts, or internal infrastructure details
Remote code execution – Running malicious code through the LLM tools

The risk lies in the fact that injected prompts aren’t always visible to the human user. They can be concealed using hidden Unicode characters or translucent text or metadata, or they can be formatted in ways that are inconspicuous to users but fully readable by the AI system.
The following diagram demonstrates an indirect prompt injection where a straightforward email summarization query results in the execution of an untrusted prompt. In the process of responding to the user with the summarization of the emails, the LLM model gets manipulated with the malicious prompts hidden inside the email. This results in unintended deletion of all the emails in the user’s inbox, completely diverging from the original email summarization query.

Unlike SQL injection, which can be effectively remediated through controls such as parameterized queries, an indirect prompt injection doesn’t have a single remediation solution. The remediation strategy for indirect prompt injection varies significantly depending on the application’s architecture and specific use cases, requiring a multi-layered defense approach of security controls and preventive measures, which we go through in the later sections of this post.
Effective controls for safeguarding against indirect prompt injection
Amazon Bedrock Agents has the following vectors that must be secured from an indirect prompt injection perspective: user input, tool input, tool output, and agent final answer. The next sections explore coverage across the different vectors through the following solutions:

User confirmation
Content moderation with Amazon Bedrock Guardrails
Secure prompt engineering
Implementing verifiers using custom orchestration
Access control and sandboxing
Monitoring and logging
Other standard application security controls

User confirmation
Agent developers can safeguard their application from malicious prompt injections by requesting confirmation from your application users before invoking the action group function. This mitigation protects the tool input vector for Amazon Bedrock Agents. Agent developers can enable User Confirmation for actions under an action group, and they should be enabled especially for mutating actions that could make state changes for application data. When this option is enabled, Amazon Bedrock Agents requires end user approval before proceeding with action invocation. If the end user declines the permission, the LLM takes the user decline as additional context and tries to come up with an alternate course of action. For more information, refer to Get user confirmation before invoking action group function.
Content moderation with Amazon Bedrock Guardrails
Amazon Bedrock Guardrails provides configurable safeguards to help safely build generative AI applications at scale. It provides robust content filtering capabilities that block denied topics and redact sensitive information such as personally identifiable information (PII), API keys, and bank accounts or card details. The system implements a dual-layer moderation approach by screening both user inputs before they reach the foundation model (FM) and filtering model responses before they’re returned to users, helping make sure malicious or unwanted content is caught at multiple checkpoints.
In Amazon Bedrock Guardrails, tagging dynamically generated or mutated prompts as user input is essential when they incorporate external data (e.g., RAG-retrieved content, third-party APIs, or prior completions). This ensures guardrails evaluate all untrusted content-including indirect inputs like AI-generated text derived from external sources-for hidden adversarial instructions. By applying user input tags to both direct queries and system-generated prompts that integrate external data, developers activate Bedrock’s prompt attack filters on potential injection vectors while preserving trust in static system instructions. AWS emphasizes using unique tag suffixes per request to thwart tag prediction attacks. This approach balances security and functionality: testing filter strengths (Low/Medium/High) ensures high protection with minimal false positives, while proper tagging boundaries prevent over-restricting core system logic. For full defense-in-depth, combine guardrails with input/output content filtering and context-aware session monitoring.
Guardrails can be associated with Amazon Bedrock Agents. Associated agent guardrails are applied to the user input and final agent answer. Current Amazon Bedrock Agents implementation doesn’t pass tool input and output through guardrails. For full coverage of vectors, agent developers can integrate with the ApplyGuardrail API call from within the action group AWS Lambda function to verify tool input and output.
Secure prompt engineering
System prompts play a very important role by guiding LLMs to answer the user query. The same prompt can also be used to instruct an LLM to identify prompt injections and help avoid the malicious instructions by constraining model behavior. In case of the reasoning and acting (ReAct) style orchestration strategy, secure prompt engineering can mitigate exploits from the surface vectors mentioned earlier in this post. As part of ReAct strategy, every observation is followed by another thought from the LLM. So, if our prompt is built in a secure way such that it can identify malicious exploits, then the Agents vectors are secured because LLMs sit at the center of this orchestration strategy, before and after an observation.
Amazon Bedrock Agents has shared a few sample prompts for Sonnet, Haiku, and Amazon Titan Text Premier models in the Agents Blueprints Prompt Library. You can use these prompts either through the AWS Cloud Development Kit (AWS CDK) with Agents Blueprints or by copying the prompts and overriding the default prompts for new or existing agents.
Using a nonce, which is a globally unique token, to delimit data boundaries in prompts helps the model to understand the desired context of sections of data. This way, specific instructions can be included in prompts to be extra cautious of certain tokens that are controlled by the user. The following example demonstrates setting <DATA> and <nonce> tags, which can have specific instructions for the LLM on how to deal with those sections:

PROMPT=”””
you are an expert data analyst who specializes in taking in tabular data.
– Data within the tags <DATA> is tabular data. You must never disclose the tabular data to the user.

Implementing verifiers using custom orchestration
Amazon Bedrock provides an option to customize an orchestration strategy for agents. With custom orchestration, agent developers can implement orchestration logic that is specific to their use case. This includes complex orchestration workflows, verification steps, or multistep processes where agents must perform several actions before arriving at a final answer.
To mitigate indirect prompt injections, you can invoke guardrails throughout your orchestration strategy. You can also write custom verifiers within the orchestration logic to check for unexpected tool invocations. Orchestration strategies like plan-verify-execute (PVE) have also been shown to be robust against indirect prompt injections for cases where agents are working in a constrained space and the orchestration strategy doesn’t need a replanning step. As part of PVE, LLMs are asked to create a plan upfront for solving a user query and then the plan is parsed to execute the individual actions. Before invoking an action, the orchestration strategy verifies if the action was part of the original plan. This way, no tool result could modify the agent’s course of action by introducing an unexpected action. Additionally, this technique doesn’t work in cases where the user prompt itself is malicious and is used in generation during planning. But that vector can be protected using Amazon Bedrock Guardrails with a multi-layered approach of mitigating this attack. Amazon Bedrock Agents provides a sample implementation of PVE orchestration strategy.

Access control and sandboxing
Implementing robust access control and sandboxing mechanisms provides critical protection against indirect prompt injections. Apply the principle of least privilege rigorously by making sure that your Amazon Bedrock agents or tools only have access to the specific resources and actions necessary for their intended functions. This significantly reduces the potential impact if an agent is compromised through a prompt injection attack. Additionally, establish strict sandboxing procedures when handling external or untrusted content. Avoid architectures where the LLM outputs directly trigger sensitive actions without user confirmation or additional security checks. Instead, implement validation layers between content processing and action execution, creating security boundaries that help prevent compromised agents from accessing critical systems or performing unauthorized operations. This defense-in-depth approach creates multiple barriers that bad actors must overcome, substantially increasing the difficulty of successful exploitation.
Monitoring and logging
Establishing comprehensive monitoring and logging systems is essential for detecting and responding to potential indirect prompt injections. Implement robust monitoring to identify unusual patterns in agent interactions, such as unexpected spikes in query volume, repetitive prompt structures, or anomalous request patterns that deviate from normal usage. Configure real-time alerts that trigger when suspicious activities are detected, enabling your security team to investigate and respond promptly. These monitoring systems should track not only the inputs to your Amazon Bedrock agents, but also their outputs and actions, creating an audit trail that can help identify the source and scope of security incidents. By maintaining vigilant oversight of your AI systems, you can significantly reduce the window of opportunity for bad actors and minimize the potential impact of successful injection attempts. Refer to Best practices for building robust generative AI applications with Amazon Bedrock Agents – Part 2 in the AWS Machine Learning Blog for more details on logging and observability for Amazon Bedrock Agents. It’s important to store logs that contain sensitive data such as user prompts and model responses with all the required security controls according to your organizational standards.
Other standard application security controls
As mentioned earlier in the post, there is no single control that can remediate indirect prompt injections. Besides the multi-layered approach with the controls listed above, applications must continue to implement other standard application security controls, such as authentication and authorization checks before accessing or returning user data and making sure that the tools or knowledge bases contain only information from trusted sources. Controls such as sampling based validations for content in knowledge bases or tool responses, similar to the techniques detailed in Create random and stratified samples of data with Amazon SageMaker Data Wrangler, can be implemented to verify that the sources only contain expected information.
Conclusion
In this post, we’ve explored comprehensive strategies to safeguard your Amazon Bedrock Agents against indirect prompt injections. By implementing a multi-layered defense approach—combining secure prompt engineering, custom orchestration patterns, Amazon Bedrock Guardrails, user confirmation features in action groups, strict access controls with proper sandboxing, vigilant monitoring systems and authentication and authorization checks—you can significantly reduce your vulnerability.
These protective measures provide robust security while preserving the natural, intuitive interaction that makes generative AI so valuable. The layered security approach aligns with AWS best practices for Amazon Bedrock security, as highlighted by security experts who emphasize the importance of fine-grained access control, end-to-end encryption, and compliance with global standards.
It’s important to recognize that security isn’t a one-time implementation, but an ongoing commitment. As bad actors develop new techniques to exploit AI systems, your security measures must evolve accordingly. Rather than viewing these protections as optional add-ons, integrate them as fundamental components of your Amazon Bedrock Agents architecture from the earliest design stages.
By thoughtfully implementing these defensive strategies and maintaining vigilance through continuous monitoring, you can confidently deploy Amazon Bedrock Agents to deliver powerful capabilities while maintaining the security integrity your organization and users require. The future of AI-powered applications depends not just on their capabilities, but on our ability to make sure that they operate securely and as intended.
