SAME PROMPT · ONE SHOT · REAL COSTS

The Model Arena

We give frontier models the same prompt, one shot each, thinking modes on where available. Every round below is blind: vote for the render you think looks best, and every contestant in that round reveals — model name, cost, time — the moment you vote. Every artifact is playable, untouched, exactly as generated.

This is open source — run your own showdown One command turns your prompt into a side-by-side comparison video with the real bill. Runs entirely on your machine; a bundled example lets you try it without an API key.
