What is Muse Wonder?
Muse Wonder is an AI model from Meta Superintelligence Labs. It launched on 12 October 2026, alongside a second, more capable variant called Muse Wonder Full.
You can use Muse Wonder in two places: on the Meta Model API, where its model ID is muse-wonder-1.0, and in Muse Code. Muse Wonder Full is different: it is available only to Muse Code subscribers and is not on the API at all. Neither Muse Wonder nor Muse Wonder Full is open-weight.

Muse Code subscription tiers

- Everyday: $5/mo
- High: $15/mo
- Power: $50/mo
- Maximum: $200/mo
Only the Power and Maximum tiers include Muse Wonder Full.
Subscriptions default to Contributor mode, which means Meta may train on your prompts and code. An opt-out exists.
How to access Muse Wonder
There are two ways in: the Meta Model API, which requires billing to be set up, or a Muse Code subscription.
As of mid-October 2026, Muse Wonder had not reached the consumer Muse app. Subscribers were given access first, and no date has been announced for the app.
Is Muse Wonder free?
No. There is no free API route to Muse Wonder. Two different things are often mistaken for a free version of Wonder:
- The Muse app, one of the free things people confuse it with, runs Muse Spark — a different model.
- Muse Spark Open’s weights, which are free to download — also a different model.
Not to be confused with Muse Spark Open
Muse Spark Open is a separate model, released on 15 October 2026. Unlike Wonder, it is open-weights: 816B total parameters with 42B active parameters in a mixture-of-experts (MoE) design, and a 1M-token context window. Its weights are free on Hugging Face, as meta-models/Muse-Spark-Open-816B-A42B.
Running it yourself takes serious hardware: around 1.6TB of memory in BF16, or around 530GB in NVFP4. For most people, a hosted API is the realistic route. Hosted providers include Baseten, Fireworks, Groq, Modal, Nebius, OpenRouter and Together. OpenRouter has been cited at $1.25 per 1M input tokens (reported).
