Large language models (LLMs) have significantly reshaped the landscape of Artificial Intelligence (AI) since their emergence. These models provide a strong framework for challenging reasoning and problem-solving problems, revolutionizing numerous AI disciplines. LLMs are adaptable agents capable of various tasks thanks to their capacity to compress huge amounts of knowledge into neural networks. They can carry out jobs that were previously thought to be reserved for humans, such as creative endeavors and expert-level problem-solving when given access to a chat interface. Applications ranging from chatbots and virtual assistants to language translation and summarization tools have been created as a result of this transition.

LLMs perform as generalist agents, working with other systems, resources, and models to achieve goals established by people. This includes their ability to follow multimodal instructions, run programs, use tools, and more. This opens up new possibilities for AI applications, including those in autonomous vehicles, healthcare, and finance. Despite their outstanding powers, LLMs have come under fire for their lack of repeatability, steerability, and service provider accessibility.

In recent research, a group of researchers has introduced QWEN1, which marks the initial release of the team’s comprehensive large language model series, i.e., the QWEN LLM series. QWEN is not one particular model but rather a collection of models with varied parameter counts. The two primary categories in this series are QWEN, which stands for base pretrained language models, and QWEN-CHAT, which stands for chat models that have been refined using human alignment methods.

In a variety of downstream tasks, the base language models, represented by QWEN, have consistently displayed outstanding performance. These models have a thorough comprehension of many different domains thanks to their substantial training in a variety of textual and coding datasets. They are valuable assets for a variety of applications due to their adaptability and capacity for success across various activities.

On the other side, the QWEN-CHAT models are created especially for interactions and talks in natural language. They have undergone thorough fine-tuning using human alignment methodologies, including Reinforcement Learning from Human Feedback (RLHF) and supervised fine-tuning. Particularly, RLHF has been quite successful at improving the functionality of these chat models.

In addition to QWEN and QWEN-CHAT, the team has also introduced two specialized variants in the model series, specifically designed for coding-related tasks. Called CODE-QWEN and CODE-QWEN-CHAT, these models have undergone rigorous pre-training on large datasets of code, followed by fine-tuning to excel in tasks involving code comprehension, creation, debugging, and interpretation. While they may slightly lag behind proprietary models, these models vastly outperform open-source counterparts in terms of performance, making them an invaluable tool for academics and developers.

Similar to this, MATH-QWEN-CHAT has also been developed, which focuses on solving mathematical puzzles. When it comes to jobs involving mathematics, these models perform far better than open-source models and come close to matching the capabilities of commercial models. In conclusion, QWEN marks an important turning point in the creation of extensive language models. It includes a wide variety of models, which can collectively reveal the transformational potential of LLMs in the field of AI, exhibiting their superior performance over open-source alternatives.
