LMArena
LMArena is an open-source platform developed by the SkyLab team at UC Berkeley that focuses on large-scale language model evaluation. Users can interact with more than 70 AI models and vote through anonymous matchmaking or direct comparison, and the platform generates real-time leaderboards based on the Elo rating system. The platform has collected more than 2.8 million community votes, providing a transparent and neutral model performance reference for researchers, developers and general users.
