Review
Moody and cinematic: heavy slanting rain over the whole frame, a moon with a shimmering reflection path, a bright lantern throwing a long beam cone through the rain, a red-and-white tower and cottage, and white spray bursting off black rocks.
The full review
Moody and cinematic: heavy slanting rain over the whole frame, a moon with a shimmering reflection path, a bright lantern throwing a long beam cone through the rain, a red-and-white tower and cottage, and white spray bursting off black rocks. It's the best 'beam cutting through rain' in the row.
Verdict by the AI judge (provisional).
OK. Finished on its own after 33.5 min and produced lighthouse.svg.
Bugs
- The sea itself is fairly flat beyond the spray bursts (few breaking wave shapes)
- Headland rocks read as dark blobs with little form

- 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.
