The full review
A crisp red-and-white lighthouse (lantern, gallery, glow) on a dark headland throws a long beam through visible rain streaks, over a layered sea with a moon reflection column. The headland is one flat black mass with no detail, the waves are stylised bands that never break on the rocks, and the moon is a flat disc.
Verdict by the AI judge (provisional).
OK. Finished on its own after 36.1 min and produced lighthouse.svg.
Bugs
- headland is a flat black mass
- waves never break
- flat moon

- 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. A draft score until the reviewer checks it. Rubric: Wave-1 SVG scoring rubric (AI Model Reviewer).

- 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
agentic harness (save the file; self-render allowed), 378 characters. Every result for this prompt
Create an SVG of a lighthouse on a rocky headland at night: stormy sea, the lighthouse beam cutting through rain and mist, moonlight on the waves, as atmospheric and painterly as you can. Save it as lighthouse.svg in the current directory. You may render and inspect your own output (headless chromium is available at /usr/bin/chromium) and iterate on your own before finishing.

Tokens from Grok Build's own per-session usage.json (inputTokens include cached reads; uncached = input - cachedRead; outputTokens include reasoning). Harness total = Grok Build costUsdTicks / 1e10 (its own xAI price table, incl. >200K tiers). Tool calls/turns from the ACP updates.jsonl.
Prices: models.dev catalog as loaded by OpenCode 1.18.32 (read 2026-09-23); matches the xAI list price ($2 in / $0.50 cached / $6 out). Requests whose context exceeds 200K bill at 2x ($4/$1/$12); per-request context is not logged by OpenCode, so the base rate is applied (Grok Build's own cost figure does apply its tiers), 2026-09-23.
