No rubric for this prompt
Visitor votes and reviewer grades are not available yet.
- 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. No AI-judge score exists for this result: there is no rubric for this prompt, so no score is shown and none is made up.
- 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), 561 characters. Every result for this prompt
Generate an SVG of a California brown pelican riding a bicycle. The bicycle must have spokes and a correctly shaped bicycle frame. The pelican must have its characteristic large pouch, and there should be a clear indication of feathers. The pelican must be clearly pedaling the bicycle. The image should show the full breeding plumage of the California brown pelican. Save it as brown_pelican.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 $6.70, as reported by OpenCode (its own bill for the run). The list-price estimate from the token counts is $6.70.
| Tokens by type | Tokens | $ per 1M | Cost |
|---|---|---|---|
| Input (uncached) | 50 | $10.00 | $0.0005 |
| Cache write | 140,454 | $12.50 | $1.7557 |
| Cache read | 1,896,732 | $0.25 | $0.4742 |
| Output | 24,792 | $50.00 | $1.2396 |
| reasoning | 64,673 | $50.00 | $3.2336 |
- Total computed from tokens
- $6.7036
- Total reported by the harness
- $6.7036
- Difference
- computed 3.4700 vs harness 6.7036
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
- A well-known benchmark author's detailed pelican prompt, verbatim from the image alt text of the post (his own comment in brackets after it left out).
- 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
