Review
Showcase silver MacBook Pro 16 in a clean three-quarter view: notch with camera, a macOS menu bar and dock over a Sonoma-style wave wallpaper, a soft purple under-glow, a black keyboard well, speaker grilles, a huge centred trackpad and side ports, with lid and base sharing one convincing perspective. Only nit: the keys are small and slightly soft at this size.
Verdict by the AI judge (provisional).
The full review
OK. Finished on its own after 26.9 min and produced macbook.svg.
Attempt 2 of 3
Every try of this model in this harness on this prompt, oldest first. A later attempt is the cell's result: attempt 3.

Draft score — stored total; criterion breakdown unavailable. the per-criterion marks could not be read, so the stored score is shown; the displayed total has not been verified through a criterion breakdown.
- 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.

Cost breakdown
Headline cost $5.39, as reported by OpenCode (its own bill for the run). The list-price estimate from the token counts is $5.39.

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.
- 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
