ok here it is - my first Opus 5.5 vibecoded threejs 3D experience my God!! Opus is creative!! I made a road that forgets which way is down. It folds 90° up a yellow wall, runs upside down across a ceiling, and turns into sheet music: steer through the notes to play each street's melody. Watercolour. Ink. A radio on the roof. #vibejam Build it as index.html (plus any local asset files you create) in the current directory. Three.js may load from a pinned CDN. You may serve it locally and open it in headless chromium (/usr/bin/chromium, software WebGL, no GPU) to screenshot and inspect your own output, and iterate on your own before finishing. Close any browser you open as soon as you've taken your screenshot.

Cost breakdown
Headline cost $0.081, as reported by OpenCode (its own bill for the run). The list-price estimate from the token counts is $0.068.
| Tokens by type | Tokens | $ per 1M | Cost |
|---|---|---|---|
| Input (uncached) | 6 | $10.00 | $0.0001 |
| Cache write | 5,333 | $10.00 | $0.0533 |
| Cache read | 5,057 | $1.00 | $0.0051 |
| Output | 188 | $50.00 | $0.0094 |
| of which reasoning | 0 | billed as output |
- Total computed from tokens
- $0.0678
- Total reported by the harness
- $0.0812
- Difference
- Harness-reported $0.0812 vs list-price estimate $0.0678 (-16.4%); the harness figure is the headline.
OpenCode 1.18.32 reported its own total; token counts x list prices shown beside it. Cache writes priced at the input rate (the price table has no separate cache-write price). The harness reports reasoning tokens separately from output; here output includes them (188 visible + 0 reasoning), and both bill at the output rate.

Run notes
- frozen prompt (reconstructed): recovery/prompts_recovered/folding_road_threejs.assembled_candidate.txt: verbatim ask + recorded harness suffix
- plain OpenCode config copy (providers only; no ECC instructions/agents)
- opencode export written to a file (not piped)
- Run on a GitHub Codespace (codespaces lane of box-fleet); model calls reached the providers through a credential relay on the home machine (no keys in the codespace).
- Mode: interactive TUI in tmux (160x48), inside bubblewrap sandbox
- Isolation audit: none
