One prompt. Six models. No second chances.
LLM Arena is a static showcase of precomputed model outputs. Same prompt, same rules, first response only. Vote blind, then reveal who built what.
Precomputed
No live generation per visitor, no surprise API bill, no moving target.
One shot
Every model gets the identical prompt and the first answer is what ships.
Rendered
For builds, you see the actual artifact in a sandboxed browser frame.
Showdowns
Real one-shot model outputs, reviewed and published.
Snake Game
Six models get one shot at a playable browser Snake game.
Fake Startup Landing Page
A fictional AI dog-walking startup landing page, generated in one shot.
iOS Calculator Clone
Six models try to recreate the Apple calculator as a single HTML file.
Pelican On A Bicycle
A visual gotcha: can the model draw a recognizable pelican riding a bicycle?
Count The R's
A tiny deterministic gotcha with an embarrassingly clear answer.
Roast My Code
A personality test that still has to spot the real async bug.
