The exact prompt
as run, 725 characters. Every result for this prompt
Build a conceptual X-16 engine in 3D with Three.js: four cylinder banks, one crankshaft and exposed mechanics inspired by experimental multi-bank engine architectures. Make it animate (pistons, rods and crank moving in sync) with orbit controls. Everything is built in code from Three.js geometry, shaders and materials; no external models or textures. Build it as a single self-contained index.html in the current directory. Three.js may load from a CDN or be vendored. 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 $0.67, as reported by OpenCode (its own bill for the run). The list-price estimate from the token counts is $0.67.
| Tokens by type | Tokens | $ per 1M | Cost |
|---|---|---|---|
| Input (uncached) | 31,749 | $3.00 | $0.0952 |
| Cache write | 0 | $3.00 | $0 |
| Cache read | 236,288 | $0.30 | $0.0709 |
| Output | 33,347 | $15.00 | $0.5002 |

OpenCode 1.18.32 reported its own total; token counts x list prices shown beside it. The harness reports reasoning tokens separately from output; here output includes them (2,542 visible + 30,805 reasoning), and both bill at the output rate.

Run notes
- frozen prompt (written): engine/prompts_written/x16_engine.txt: a new test's prompt written by us from the project lead's brief (zero results)
- 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
