Meta Muse Wonder: the new model set to power Meta's Muse

Muse Wonder is Meta's most capable AI model so far, built to work through real chores like insurance claims and leases. Developers can use it today.

What it is

Meta introduced Muse Wonder and Muse Wonder Full on October 12, which it calls its most capable models to date. They are built for agentic tasks, meaning jobs the AI works through for you instead of just answering a question. Meta's examples: navigating an insurance claim, making sense of a lease, or building a working app. Meta says the models bring this to expert areas such as law, finance and health.

This is not the Muse app we covered on Oct 24. Muse is the assistant you text; Muse Wonder is the model family Meta says will soon power it.

Two features worth knowing

Active Memory carries what matters to you from one conversation to the next, so you don't have to repeat yourself. Active Focus keeps the model working when a task gets hard: it tries other approaches, recovers from errors, asks when something is unclear, and checks in with you before doing anything important. Think of a sharp assistant who remembers your last meeting and asks before signing anything.

Safety, per Meta

Meta says it trained the models to avoid sharing private information without permission. It says a full safety report is coming soon, so independent details are still thin.

How to try it

Muse Wonder is available today for developers through the Meta Model API and Muse Code. Muse Wonder Full is available to Muse Code subscribers. Meta says Muse Wonder will soon power the Muse assistant itself, starting with subscribers. Meta's announcement is linked below.
