Two models answer the same prompt behind a curtain. A human picks the winner without knowing who fought. Millions of these verdicts become the Elo ratings on this board.
Language, code, vision, image, and video. A champion in one ring can be a prelim fighter in another — check the divisions board before you bet.
Scores, confidence intervals, reach, and purse come straight from the public record: the Arena boards and the OpenRouter catalog, refreshed with every deploy.
No model is undefeated forever. When the crowd changes its mind, the main event changes with it — automatically.
