Review
Provençal river town 'Sainte-Ambre' on a floating isometric slab: about 30 buildings (church with spire, watermill with a wheel, tower, market stalls, townhouses) reused from a 23-symbol sprite sheet, a plaza with a fountain, a river with a stone bridge, boats and quays, trees in autumn tones. Clean z-ordering throughout. The sky carries two large flat translucent green ellipses that read as a rendering glitch rather than haze.
Verdict by the AI judge (provisional).
The full review
OK. Finished on its own after 40.7 min and produced town.svg.
Bugs
- two flat translucent green ellipses float across the sky
- roads are wide sandy plazas rather than clear streets

- 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).
- 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
agentic harness (save the file; self-render allowed), 401 characters. Every result for this prompt
Create an isometric SVG town: first design a small sprite sheet of distinct buildings (in <defs>), then place 20+ of them on an isometric grid with roads, trees, a river and a bridge. Pick your own theme and palette. Save it as town.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.
