Arena Intelligence, Inc.

Arena Intelligence, Inc. operates Arena (formerly LMArena), a community-powered platform for understanding real-world AI performance. Created by researchers from UC Berkeley, the platform has users test frontier models and provide feedback on responses, which in turn shapes a public leaderboard and human-centered model evaluations. Millions of people use Arena each month, and tens of millions of builders, researchers and creative professionals form its community.

The company's technical work spans AI model evaluation, large language model benchmarking, human feedback collection, leaderboard ranking systems, and assessment of AI reliability and alignment. Its outputs include the Arena Platform, where users interact with frontier models; a public leaderboard of model performance grounded in real-world use and community feedback; and model evaluations built from that feedback, used by enterprises and AI labs to understand reliability, alignment and impact. The leaderboard is described as trusted by leading enterprises and AI labs.

Arena states its mission as measuring and advancing the frontier of AI for real-world use, with a vision of building the foundation for everyone to understand, shape and benefit from AI. Its working emphasis is on transparent, rigorous and human-centered evaluation, with development shaped by feedback from its user community.
