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, 594 characters. Every result for this prompt
Build a complete, polished mobile-first 3D arcade game in Three.js as one self-contained index.html (no external assets; all geometry, textures and sound procedural). Portrait orientation, touch controls (swipe/drag and tap) with keyboard fallback for desktop. Include a title screen, at least 3 increasing difficulty phases, score and best-score persistence in localStorage, juicy feedback (screen shake, particles, procedural Web Audio sfx), pause/resume when the tab is hidden, and a game-over screen with restart. Must hold 60 fps on a mid-range phone; keep draw calls low with instancing.

Cost breakdown
Headline cost $6.15, as reported by OpenCode (its own bill for the run). The list-price estimate from the token counts is $5.88.
| Tokens by type | Tokens | $ per 1M | Cost |
|---|---|---|---|
| Input (uncached) | 90 | $10.00 | $0.0009 |
| Cache write | 109,951 | $10.00 | $1.0995 |
| Cache read | 2,131,010 | $1.00 | $2.1310 |
| Output | 52,941 | $50.00 | $2.6471 |
| of which reasoning | 15,828 | billed as output |
- Total computed from tokens
- $5.8785
- Total reported by the harness
- $6.1533
- Difference
- Harness-reported $6.1533 vs list-price estimate $5.8785 (-4.5%); the harness figure is the headline.
OpenCode 1.18.32 reported its own total; token counts x list prices shown beside it. Cache writes priced at the input rate (the price table has no separate cache-write price). The harness reports reasoning tokens separately from output; here output includes them (37,113 visible + 15,828 reasoning), and both bill at the output rate.

Run notes
- frozen prompt (written): written 2026-10-06 from the X idea scan (prompts_queue; X_IDEAS.md 2026-10-06 entries) for MR wave n1; category threejs; zero results
- plain OpenCode config copy (providers only; no ECC instructions/agents)
- default skills on: 79 skills in this run's xdg/config/opencode/skills
- opencode export written to a file (not piped)
- Mode: interactive TUI in tmux (160x48), inside bubblewrap sandbox
- Isolation audit: outside paths seen
- Renderer: Three.js r170 embedded inline (the minified library sits inside index.html; REVISION 170 at line 3957) driving a WebGLRenderer (WebGL 2), with an HTML/inline-SVG touch-control overlay and Web Audio sound, in one self-contained ~574 KB HTML file; no CDN, no external assets. Needs a WebGL-capable browser (any current desktop or mobile browser); no WebGPU needed.
- Card video: the run's own video.mp4 (H.264 yuv420p, unchanged). Poster: the run's own render.png.
- Same frozen prompt as the other rows on this test; configurations differ and all rows are unscored, so this is not a head-to-head result.
