Review
Strong space-grey MacBook Pro 16 in a consistent three-quarter view: notch, menu bar and a dock of app icons on a soft blue wallpaper, a keyboard with legends and arrow keys, speaker grilles either side, a large trackpad, side ports and a front notch, with a subtle blue under-glow. The base is drawn too thick for a MacBook, and the screen throws little light onto the deck.
Verdict by the AI judge (provisional).
The full review
OK. Finished on its own after 32.2 min and produced macbook.svg.
Bugs
- base slab too thick
- little screen light on the deck

Visitor votes and reviewer grades are not available yet.
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 $2.40, as reported by OpenCode (its own bill for the run). The list-price estimate from the token counts is $2.40.
| Tokens by type | Tokens | $ per 1M | Cost |
|---|---|---|---|
| Input (uncached) | 358,448 | $1.40 | $0.5018 |
| Cache write | 0 | $0.00 | $0 |
| Cache read | 5,124,545 | $0.26 | $1.3324 |
| Output | 31,615 | $4.40 | $0.1391 |
| reasoning | 97,043 | $4.40 | $0.4270 |

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).

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
