Review
Autumn harbour town at dusk: about 35 buildings (half-timbered houses, a town hall with a clock, a church spire, a warehouse, boathouses and a striped lighthouse) placed from a 43-symbol sprite sheet with 346 reuses, lamp posts, a fountain, orange trees and pines, a river mouth with a stone bridge, a jetty, sailboats and buoys. Z-ordering is clean. The backdrop clashes: a moonlit night sky sits over a peach sunset gradient below the slab, and the lighthouse beam is a flat grey wedge.
Verdict by the AI judge (provisional).
The full review
OK. Finished on its own after 47.5 min and produced town.svg.
Bugs
- night sky with moon over a sunset-peach lower background (time of day disagrees)
- lighthouse beam is a flat grey triangle

- 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.
Downloads
Files actually published for this run. Original output, site-made previews and post-run conversions are labelled separately.
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.

Cost breakdown
Headline cost $9.37, as reported by OpenCode (its own bill for the run). The list-price estimate from the token counts is $9.37.

Tokens from OpenCode per-message usage; harness total = sum of OpenCode per-message cost. OpenCode reports reasoning separately; both bill at the output rate (output line here = output only, see reasoning).
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.
