Arena AI

Created by researchers from UC Berkeley, Arena (formerly LMArena) is a community-powered platform for understanding AI performance in the real world. Tens of millions of builders, researchers, and creative professionals come to Arena to use frontier models and give feedback on their responses, shaping a public leaderboard grounded in real-world use.

Anyone can come to compare top frontier AI models and see how they perform on the leaderboards by modality, expert categories, occupational fields, and more. Discover which model is best for you, and join us in building the world’s best community-driven evaluation platform for frontier AI.
