Claude Sonnet 5.5 in Claude Code 2.1.280
skills off
Zoom, inline player and more ways to view
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).

Scores
AI judge
Not scored
No rubric for this prompt
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, 909 characters. Every result for this prompt
Build a single-page Three.js scene (one index.html file, no build step, three.js from a pinned CDN) with a rigged humanoid character (a procedural skeleton and simple body meshes are fine) that plays walk, run and jump cycles, with on-screen buttons or keys to switch between them and blend smoothly from one to the next. The motion must look human, not spider-like: respect realistic joint limits (knees and elbows bend one way only, no joint rotates past a human range), feet plant on the ground with no sliding while in contact, the pelvis bobs and the torso stays upright with natural counter-rotation of shoulders and hips, and arms swing opposite to the legs. Include a ground grid, an orbit camera and a toggle that shows the skeleton. It must run at 60 fps in a desktop browser and work with touch. Write everything into the working directory and finish with a short README.md describing the controls.
