About Arena AI

Arena AI is a crowdsourced platform where users submit prompts to two anonymous AI models simultaneously and vote on the better response. The platform aggregates these votes into a public Elo-based leaderboard that ranks models across categories such as text, coding, math, creative writing, and image generation. Originally launched in 2023 as Chatbot Arena by UC Berkeley researchers, it has since expanded to include over 360 models and serves millions of monthly active users worldwide. The service is free to use with no account required for basic access, though an enterprise AI Evaluations tier is available for structured commercial testing. Users can compare models without bias by evaluating responses anonymously, helping the community identify strengths and weaknesses across different AI systems. The platform’s leaderboard provides a transparent, data-driven way to track model performance over time. It is designed for researchers, developers, and enthusiasts interested in AI model evaluation and benchmarking.
