The full review
A clean light-studio product shot with a strong wallpaper and crisp aluminium, keyboard, trackpad and speaker grilles. The lid is drawn close to front-on while the base is angled, so the two halves don't quite share one vanishing point, and with a white backdrop the 'screen glow' barely reads. No menu bar or dock.
Verdict by the AI judge (provisional).
OK. Finished on its own after 15.8 min and produced macbook.svg.
Bugs
- Lid perspective is flatter than the base (inconsistent vanishing)
- No UI on screen (no menu bar/dock/clock)
- Screen glow weak against the light background

- 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), 373 characters. Every result for this prompt
Generate an SVG that looks like a realistic 3D render of a MacBook Pro 16" (opened, slight three-quarter view, screen glow, aluminum body). Use gradients and perspective to fake the 3D. Save it as macbook.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.

Run notes
- Playcode MacBook SVG Benchmark prompt verbatim, except its last sentence ("Respond with ONLY the SVG markup, no explanation.") is swapped for the save-to-file harness suffix, as the prompt research recommends for harness runs.
- per-request tiering: requests with a prompt above 272K tokens billed at 2x input/cache, 1.5x output
- Mode: interactive TUI in tmux (160x48), inside bubblewrap sandbox
- Isolation: bwrap: private /tmp, HOME and TMPDIR inside run dir, own CLAUDE_CONFIG_DIR/CODEX_HOME copy; the project files, other runs, /tmp/hx_* not mounted
