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), 234 characters. Every result for this prompt
Create an SVG image of an Xbox 360 controller. Save it as xbox360.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 $1.34, as reported by OpenCode (its own bill for the run). The list-price estimate from the token counts is $1.27.
| Tokens by type | Tokens | $ per 1M | Cost |
|---|---|---|---|
| Input (uncached) | 26,750 | $10.00 | $0.2675 |
| Cache read | 221,131 | $1.00 | $0.2211 |
| Output | 15,625 | $50.00 | $0.7812 |

- Total computed from tokens
- $1.2699
- Total reported by the harness
- $1.3367
- Difference
- computed 1.2699 vs harness 1.3367
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).
Prices: Project price table; OpenAI Standard tier, requests whose prompt is >272K tokens bill at 2x input/cache and 1.5x output (applied per request where per-request usage is logged), 2026-09-22.
Run notes
- The original post's exact prompt, verbatim, except its output-format lines ("Output it in a Markdown multi-line code block. Like this: ```svg ... ```") are swapped for the save-to-file harness suffix, as in wave 1.
- 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 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
