Open the original page

The model's own page, run in a sandboxed frame only when you ask (a page that needs its own origin opens in a new tab on a separate demo site). Phones get a full-screen player capped at 1.5x pixel density (2x on larger screens) so it stays smooth; the original page runs uncapped. It starts in its auto-tour (T switches to play mode on a keyboard).

Visitor votes and reviewer grades are not available yet.

AI judge
AI judge: the test runner (model claude-opus-5-5), scoring by visual review of the 1600 px render against the pre-registered rubric. No AI-judge score exists for this result: there is no rubric for this prompt, so no score is shown and none is made up.
Visitors
Public voting with a blind reveal is coming: you score the output first, then see the other scores.
Reviewer
The reviewer's own grade appears here once it is added.

Scores compare results for the same prompt only. AI-judge boards rank runs within one prompt, equal totals sharing a rank; scores from different prompts are never averaged.

The exact prompt

as run, 1,384 characters. Every result for this prompt

Build a small playable 3D game in Three.js: an ant defends its home from a furious giant gardener. The player controls the ant on the ground of a lush garden, seen from a low third-person camera that makes the grass blades, pebbles and flowers feel huge. The gardener towers over the scene and sweeps a humming string trimmer back and forth, chasing the ant and throwing up clippings. The ant fights back with a tiny slingshot: aim with the mouse, fire pebbles at the gardener and dodge the trimmer's swings. Show a health bar for the ant and a large health bar for the gardener at the top of the screen, with hit flashes, a clear win or lose message and a restart. Warm afternoon sunlight falls through the leaves overhead, casting moving dappled light and soft shadows, with dust drifting in the light beams. Keep the controls simple (WASD or arrow keys to move, click to shoot) and show them on screen. Everything is built in code from Three.js geometry and materials; no external models or textures. Build it as index.html (plus any local asset files you create) in the current directory. Three.js may load from a pinned CDN. You may serve it locally and open it in headless chromium (/usr/bin/chromium, software WebGL, no GPU) to screenshot and inspect your own output, and iterate on your own before finishing. Close any browser you open as soon as you've taken your screenshot.
