Where you actually sign in for Muse Wonder
There are two sign-in routes to Muse Wonder, and neither of them is the consumer Muse app:
- Meta Model API — sign in to the Meta Model API and use the model ID muse-wonder-1.0. Billing is required.
- Muse Code — sign in with a Muse Code subscription. Muse Wonder Full is subscribers-only, and only on the Power and Maximum tiers.
Why Wonder isn’t in your Muse app
As of mid-October 2026, Muse Wonder had not reached the consumer Muse app. The word from Meta was subscribers first, with no date given for the app. So if you open the Muse app and cannot find Wonder, nothing is wrong at your end: Wonder missing from the app is the expected state — not a bug, and not a problem with your account or your login.
The names, untangled
Much of the confusion is naming. These are all different things:
- Muse Wonder — Meta’s model, available on the Meta Model API (model ID muse-wonder-1.0) and in Muse Code.
- Muse Wonder Full — the bigger variant; Muse Code subscribers only, on the Power and Maximum tiers, and not on the API.
- Muse Spark — a different model; it is the one that runs in the consumer Muse app.
- Muse Spark Open — the separate open-weights model; also not Wonder.
- Muse app — the consumer app, which runs Muse Spark.
- Muse Code — the subscription product through which Wonder and Wonder Full are offered.
