The full review
Stopped by us. Stopped by us (box row cap reached (2325s); stopped by the box lane so the run ships as partial); not a model failure.
Scores
Not scored: only runs that finished on their own are scored.
Downloads
Files actually published for this run. Original output, site-made previews and post-run conversions are labelled separately.
The exact prompt
as run, 346 characters. Every result for this prompt
Create an SVG illustration of a top-down map-style illustration of a city park with a pond, winding paths, a playground, trees, benches and people walking dogs. Save it as image.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.
How it was made
Versions saved during the run
2 intermediate outputs, in the order the model wrote them.
Step by step
The prompt, every agent turn and tool call (tool name and a one-line summary; inputs and outputs are not shown), then the final message. The full machine-format transcript is published as a scrubbed download.

Cost breakdown
Headline cost $0, as reported by OpenCode (its own bill for the run).
| Tokens by type | Tokens | $ per 1M | Cost |
|---|---|---|---|
| Input (uncached) | 123,874 | n/a | n/a |
| Cache write | 0 | n/a | n/a |

- Total computed from tokens
- unknown
- Total reported by the harness
- $0
OpenCode 1.18.32 reported its own total; token counts x list prices shown beside it. No list price for longcat-2.5-preview-free in config/prices.json; no estimate computed. The harness reports reasoning tokens separately from output; here output includes them (106,655 visible + 777 reasoning), and both bill at the output rate.
Run notes
- frozen prompt (written): our frozen prompt, suite svg_250 (harness variant of svg_city_park_top_down)
- plain OpenCode config copy (providers only; no ECC instructions/agents)
- opencode export written to a file (not piped)
- Mode: interactive TUI in tmux (160x48), inside bubblewrap sandbox
- Isolation audit: outside paths seen
