What it is
Muse Wonder and the larger Muse Wonder Full arrived on October 12, 2026, as Meta’s most capable models so far. Meta says they are strongest at agent tasks and at law, finance, health and coding. Two features stand out: Active Memory, which carries context from one conversation to the next, and Active Focus, which keeps the model working toward a goal when a task gets hard.
Unlike Muse Spark Open, the weights are not public.
What it costs
On the Meta Model API, Muse Wonder lists at $4 per million input tokens and $20 per million output tokens, with a 1 million token context window. Muse Wonder Full is only available inside a Muse Code subscription.
What it means for you
Meta says Muse Wonder will soon power its Muse personal agent, starting with subscribers. If you use Meta’s apps, that is where most people will meet it. Developers can try it now through the API.
