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).

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, 997 characters. Every result for this prompt
Make a complete playable game in ONE html file under 13 KB (minified size reported in a corner): the visuals are rendered entirely by one fragment shader (raymarched or 2D SDF). Arcade loop: dodge/collect, score, increasing speed, game over + restart. Keyboard and touch controls. No libraries, no assets. IDLE AUTO-PLAY: with no input, the page starts animating immediately and runs an automatic demo (camera motion, preset or seed cycling, or an AI player) so a headless capture shows constant motion. Must render on WebGL/WebGL2 with no WebGPU required. Save the main page as index.html in the current directory (plus any local asset files you create), with no build step. You may serve it locally and open it in headless chromium (/usr/bin/chromium, software WebGL, no GPU, no WebGPU) 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. Finish with a short README.md describing the controls.

Step by step
The prompt, every agent turn and tool call (tool name and a one-line summary; inputs and outputs are not shown), then the final message. The full transcript is 5.5 MB; it is published as a scrubbed, compressed download rather than shown on the page.

Cost breakdown
Headline cost $2.51, as reported by OpenCode (its own bill for the run).
| Tokens by type | Tokens | $ per 1M | Cost |
|---|---|---|---|
| Input (uncached) | 77,711 | n/a | n/a |
| Cache write | 0 | n/a | n/a |
| Cache read | 2,536,434 | n/a | n/a |
| Output | 45,090 | n/a | n/a |
- Total computed from tokens
- unknown
- Total reported by the harness
- $2.5056
OpenCode 1.18.35 reported its own total; token counts x list prices shown beside it. No list price for kimi-k3-fast in config/prices.json; no estimate computed. The harness reports reasoning tokens separately from output; here output includes them (15,465 visible + 29,625 reasoning), and both bill at the output rate.
Run notes
- frozen prompt (written): core requirements sha256 0217f6e8b2ea, full harness prompt sha256 0217f6e8b2ea; exact prompt text used by the existing harness rows of this test on the runs branch (copied from js13k_style_shader_game__claude-code__haiku-5-5__attempt1/meta.json, sha256 verified); Beta half of the
- 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: none
- Renderer: raw WebGL with the page's own shaders, no 3D library (read from the run's own 001_20261009T004339Z.html, 002_20261009T004424Z.html, 003_20261009T004429Z.html, 004_20261009T004514Z.html).
- Card video: none (the run has no H.264 yuv420p video.mp4 with 30+ frames under 24 MB). 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.
- Kimi K3 Fast is a fast-serving router over the kimi-k3 weights (Fireworks router accounts/fireworks/routers/kimi-k3-fast; responses report kimi-k3), not separate weights
- Kimi K3 (fast router) 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.
