Arena

What it does

Arena is a web platform for comparing AI models on real-world prompts. You type a prompt, and in the default Battle mode two anonymous models respond side by side. You vote for the response you prefer, and those votes feed public leaderboards for text, search, vision, and document tasks. Requests for other formats, such as video, are routed to Arena-specific experiences when the prompt makes that clear.

What sets Arena apart is its crowdsourced comparison. Model identities are revealed only after you vote, and follow-up prompts keep using the same pair until a new vote is cast. You can also pick a specific model with the @ selector, or compare two chosen models head to head. Chat mode offers a more traditional AI chat experience, while Work mode is an experimental agentic option for complex, ongoing tasks, with Connectors that can bring in tools such as Gmail and Google Drive.

Arena suits people who want to see how models handle everyday prompts or who evaluate AI for their own work. It is used through the arena.ai website. Leaderboard rankings reflect human preferences from voters rather than a fixed benchmark, and experimental features such as Work mode may not be available to every user.
