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 $0.55, as reported by OpenCode (its own bill for the run). The list-price estimate from the token counts is $0.54.
| Tokens by type | Tokens | $ per 1M | Cost |
|---|---|---|---|
| Input (uncached) | 129,226 | $0.30 | $0.0388 |
| Cache write | 0 | $0.30 | $0 |

- Total computed from tokens
- $0.5408
- Total reported by the harness
- $0.5476
- Difference
- computed $0.54 vs reported $0.55 (diff -0.01)
OpenCode 1.18.35 reported its own total; token counts x list prices shown beside it. The harness reports reasoning tokens separately from output; here output includes them (46,564 visible + 34,915 reasoning), and both bill at the output rate.

Run notes
- frozen prompt (written): core requirements sha256 951df6284d51, full harness prompt sha256 951df6284d51; exact prompt text used by the existing harness rows of this test on the runs branch (copied from threejs_mobile_touch_arcade_game__claude-code__opus-5-5-high__attempt1/meta.json, sha256 verified); Bet
- no TUI: the harness ran in its non-interactive mode, so there are no TUI screenshots; the timelapse is built from version renders only
- OpenCode config (providers only, permission allow-all except question; no agents/instructions) + both default skill kits in xdg/config/opencode/skill (skills=on)
- infra retries: 0
- in the published transcript the sandbox HOME directory is shown as <HOME>
- skills=on: 54 skills installed in the harness skill directory before launch (video-33 remotion-dev/skills + heygen-com/hyperframes@0b5db9da + f; web-threejs-21 [redacted]/ai-AI Model Reviewer skills/ (alpha/mr-homebar)@7521074d98c9).
- Mode: headless run mode (opencode run --format json), inside bubblewrap sandbox
- Isolation audit: paths_seen
- Renderer: Three.js r160 (three@0.160.1 module loaded from unpkg through an importmap) with WebGLRenderer; extra 2D canvases created by the page's script; sound through WebAudio.
- Card video: the run's own video.mp4 (H.264 yuv420p, unchanged). Poster: the run's own render.png.
- Skills on: the run had 54 skills installed (33 video + 21 web/Three.js), as its meta records.
- MiniMax M3 served via Fireworks (OpenCode provider fireworks-ai).
- 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.
