Introducing Lemur and Lemur-Chat: Versatile Language Models for Text and Code

In today’s world, where language and technology intersect, the demand for powerful and versatile language models is higher than ever. Traditional large language models (LLMs) have excelled in either understanding text or coding tasks, but rarely both. This has created a gap in the market for models that can seamlessly navigate both textual reasoning and coding proficiency. This is where Lemur and Lemur-Chat come in, offering innovative solutions to bridge this gap.

The challenge of creating language models that can effectively handle both text and code has been a long-standing one. Existing LLMs have typically been specialized for either textual comprehension or coding tasks, making it difficult for developers and researchers to find a model that excels in both areas. This has created a need for LLMs that can offer a multifaceted skill set encompassing understanding, reasoning, planning, coding, and context grounding.

While some solutions exist in the form of traditional LLMs, they have their limitations. The industry lacks models that can truly balance the intricate demands of both text and code-related tasks. This has created a void in the landscape of language model agents, where an integrated approach to understanding, reasoning, and coding is essential.

The Lemur project, a collaboration between XLang Lab and Salesforce Research, aims to address this critical gap in language model technology. Lemur and Lemur-Chat are pioneering efforts to develop open, pretrained, and supervised fine-tuned LLMs that excel in both text and code-related tasks. The foundation of this endeavor is the extensive pretraining of Llama 2 on a vast corpus of ~100 billion lines of code-intensive data. This pre-training phase is followed by supervised fine-tuning on ~300,000 instances of public instructional and dialog data. The result is a language model with enhanced coding and grounding abilities while maintaining competitive textual reasoning and knowledge performance.

The performance metrics of Lemur and Lemur-Chat speak for themselves. Lemur surpasses other open-source language models on coding benchmarks, demonstrating its coding proficiency. At the same time, it maintains its competitive edge in textual reasoning and knowledge-based tasks, showcasing its versatile skill set. Lemur-Chat also outperforms other open-source supervised fine-tuned models in various dimensions, highlighting its exceptional ability to bridge the gap between text and code in conversational contexts.

The Lemur project is a collaborative research effort with contributions from XLang Lab and Salesforce Research, with support from Salesforce Research, Google Research, and Amazon AWS. While the journey towards a balanced open-source language model is still ongoing, Lemur’s contributions have already begun reshaping the language model technology landscape. By offering a model that excels in both text and code-related tasks, Lemur provides a powerful tool for developers, researchers, and organizations navigating the increasingly intricate intersection of language and technology.

In conclusion, the Lemur project represents innovation in the world of language models. Its ability to harmoniously balance text and code-related tasks addresses a longstanding challenge in the field. As Lemur continues to evolve and set new benchmarks, it promises to drive further research on agent models and establish a more powerful and balanced foundation for open-source language models. With Lemur, the future of language model technology is brighter and more versatile than ever before.
