About LMArena

Created by researchers from UC Berkeley, LMArena is an open platform where everyone can easily access, explore and interact with the world’s leading AI models. By comparing them side by side and casting votes for the better response, the community helps shape a public leaderboard, making AI progress more transparent, and grounded in real-world usage.


The LMArena blog houses all community and product updates, as well as research and insights from community-driven model evaluation data and leaderboards.

Our Mission

To bring the best AI models to everyone, and to improve them through real-world community evaluations.

Our Vision

Create an open space to try all the best AIs and shape their future through collective feedback.
