In plain English
Meta's strongest model for long-running personal and work agents.
Good for
Complex software work, assistants that remember a lot, and tasks that carry on across many steps.
Things to be aware of
The more memory, tools and time an agent has, the more it can do and the more it can get wrong. Tighten permissions and checks as it gets more capable.
What Meta says
“Muse Wonder brings together “Active Memory” and “Active Focus” to retain relevant personal context and keep working towards a goal. These are Meta’s terms and performance claims. They aren't independent guarantees.”
