Creators of the LMSYS Arena Chatbot

The LMSYS Arena Chatbot, also known as Chatbot Arena or LMArena, represents a significant milestone in the development and evaluation of large language models (LLMs). This platform emerges from a collaborative effort primarily led by the Large Model Systems Organization (LMSYS Org) and UC Berkeley SkyLab, bringing together a team of dedicated researchers and developers committed to advancing AI benchmarking and model evaluation.

Founding Members and Initial Development

The inception of Chatbot Arena can be traced back to the collaborative efforts of Lianmin Zheng and Ying Sheng, both integral members of LMSYS, a student research collective at UC Berkeley SkyLab. Their vision was to create an open-source platform that facilitates live, community-driven evaluations of AI models, enabling direct comparisons and benchmarking through user engagements and votes. This initiative was part of a broader mission by LMSYS to develop large-scale, accessible, and scalable language models.

As detailed on the LMSYS About page, the organization has been at the forefront of pioneering LLM evaluations, further establishing their reputation with projects like Vicuna and MT-Bench. The creation of Chatbot Arena was a natural extension of their commitment to open-source development and community involvement in AI research.
