The exact prompt

as run, 721 characters. Every result for this prompt

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 $3.87, as reported by OpenCode (its own bill for the run). The list-price estimate from the token counts is $3.87.

Tokens by type	Tokens	$ per 1M	Cost
Input (uncached)	32	$4.00	$0.0001
Cache write	67,265	$5.00	$0.3363
Cache read	670,738	$0.20	$0.1341
Output	169,879	$20.00	$3.3976
of which reasoning	167,041	billed as output

Total computed from tokens: $3.8682
Total reported by the harness: $3.8682
Difference: matches

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 (2,838 visible + 167,041 reasoning), and both bill at the output rate.
