Review
Clear striped lighthouse (lantern, gallery, lit window) on a rocky point, with heavy rain streaks, a moon, and a white reflection column on a dark sea.
The full review
Clear striped lighthouse (lantern, gallery, lit window) on a rocky point, with heavy rain streaks, a moon, and a white reflection column on a dark sea. The beam is a flat banded wedge that ends in a hard straight edge at the frame, the waves barely break against the rocks, and a few stray blob shapes float in the water.
Verdict by the AI judge (provisional).
OK. Finished on its own after 23.5 min and produced lighthouse.svg.
Bugs
- beam is a hard-edged banded wedge
- waves barely break
- stray blobs in the water

- 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), 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 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.
Run notes
- Mode: interactive TUI in tmux (160x48), inside bubblewrap sandbox
- Isolation: bwrap: private /tmp and /run, private PID ns; only this run dir, harness binaries (ro), opencode config, /usr, /etc bound; HOME/TMPDIR/XDG data private; the project files and other runs not mounted
