About the Company

Arena Intelligence

Crowdsourced LLM evaluation and comparison platform

Arena Intelligence provides a crowdsourced, open platform for evaluating large language models (LLMs) by running head-to-head comparisons of two anonymous models on user prompts. Users vote on the better response and, after voting, model identities are revealed; the results generate large-scale preference data used to compute Elo ratings published on a public leaderboard. Originating from LMSYS and UC Berkeley’s Sky Computing Lab as Chatbot Arena, the project evolved into a company and rebranded to Arena, with $100 million seed funding in 2024 to scale the platform. The underlying framework, FastChat, remains open source, including the user interface and serving backend. Arena differentiates itself by providing a transparent, real-world benchmarking method that aggregates community-driven judgments and offers analytics to AI labs and enterprises, aiming to guide model development with observable performance data.
