Muse Wonder vs Opus 5.5: a one-prompt 3D game test
On launch day, a developer gave Muse Code (Muse Wonder, extra-high effort) and Claude Code (Opus 5.5, extra-high effort) the same one-shot job: a playable first-person 3D game of his kitchen in a single three.js file. He reports both ran first try; Opus took 11m40s and about $2.10, Wonder took 3m42s and about $1.
Why it matters
Side-by-side one-prompt tests are a cheap way to compare speed and cost on the kind of work you actually do.
Who it's for
Developers deciding whether to try Muse Code or Muse Wonder.
How to try it
- Write one self-contained prompt for a small app you know well.
- Run it on Muse Wonder and on your usual model with the same settings.
- Compare time, cost and whether it runs first try, then check the code quality yourself.
Plan & availability: Muse Code with Muse Wonder through the API; Wonder Full needs a larger Muse plan.
Note: reported by users on X; we haven't independently confirmed it works in the current version.
