The record

Product: Arena is an AI evaluation platform where users compare model responses and vote to shape public leaderboards.
Anonymous battles: In Battle mode, Arena presents two anonymous model responses and reveals their identities after the user votes.
Ranking method: Arena uses the Bradley-Terry rating system to aggregate votes into model rankings.
Modes: The platform offers Battle, Side by Side, and Direct modes; only anonymous Battle votes count toward official rankings.
Model arenas: Arena lists rankings for agent, text, web development, image, video, vision, document, and search tasks.
Multimedia features: Arena supports comparing models for image generation, image editing, and video generation, among other tasks.
Research datasets: Arena says its open datasets are free to access and shares a portion of anonymized voting data, including prompt text, outcomes, and model pairings.
Privacy: Arena says conversations may be used for research datasets and private model-provider evaluations, and shared data is de-identified; it advises users not to submit sensitive information.
Security and compliance: Arena’s Trust Center lists CCPA, GDPR, and NIST CSF materials and describes security, privacy, and compliance information for customer reviews.
Account requirements: Leaderboards can be viewed without signing in, while Direct, Side by Side, Image Arena, and Video Arena require login.
Account integrations: Users can create an account with Google or email, and Arena’s coding Agent Mode can connect to GitHub repositories.
Usage limit: Arena applies a daily usage limit to all users, and usage automatically resets 24 hours after the limit is reached.
Video limit: Video Arena requires login, allows two generations per 24-hour period, and supports Battle mode only.
Commercial customers: Arena offers commercial evaluation services to enterprises, model labs, and developers, with evaluation results supported by service-level agreements.
