LM Arena just moved its Video Arena from Discord to the web. The catch: you vote on which anonymous model did better. The reward: free access to Google's Veo 3, OpenAI's Sora 2, and 13 other frontier video generators.
The setup is straightforward. Enter a prompt or upload an image, get two videos back from unknown models, pick a winner. Your vote feeds the platform's text-to-video leaderboard. You can download both clips for your own use. Account required.
Battle Mode launched with 15 models: Veo 3, Sora 2, Seedance v1.5 Pro, Kling-2.6-pro, WAN-2.5, Hailuo-2.3, and others the company hasn't named publicly. LM Arena says users might "discover the next big AI model under a codename before it releases." The leaderboard already shows some anonymous entries.
This comes weeks after LM Arena announced a $150 million Series A at a $1.7 billion valuation. The platform, which started as a UC Berkeley research project called Chatbot Arena, now runs evaluations across text, code, image, video, and search. The video feature had been Discord-only until now.
The Bottom Line: Free Veo 3 and Sora 2 access in exchange for crowdsourced model rankings, with no generation limits disclosed.
