Review
A near-photographic seascape: a full moon in torn clouds, a long warm beam sweeping off a red-and-white lighthouse with a lit cottage on a craggy headland, a huge white spray burst against the cliff and a teal-lit rolling wave in the foreground, with rain streaks over everything. The most dramatic surf in the row. It spent 75 minutes and 236 tool calls refining it.
Verdict by the AI judge (provisional).
The full review
OK. Finished on its own after 75.4 min and produced lighthouse.svg.
Bugs
- Lighthouse is small relative to the frame
- Rain is faint, so the beam reads more as clear-air than 'cutting through rain'
- Moonlight on the water is modest compared with the Fable and DeepSeek versions

- 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.
