Meta Introduces the Muse Wonder Model Family

Meta introduced the Muse Wonder model family, which includes Muse Wonder and Muse Wonder Full. The company announced the release in October 2026, calling these its most capable models to date.

The models are designed for expert tasks in law, finance, and medicine, as well as programming for those building games, apps, or services for a new business. According to Meta, they deliver leading results on agentic tasks of a personal and work-related nature: working through an insurance case, understanding lease terms, or making sense of someone's finances. The company describes Muse Wonder as an evolution of the approach it began with Muse Spark and the outcome of a fourteen-month restructuring of its AI efforts.

Memory and Focus

The family's key features are Active Memory and Active Focus. The first carries meaningful context between conversations and brings back the details needed for the current task. The second helps you not abandon a difficult task: trying other approaches, recovering from mistakes, clarifying details when needed, and checking before doing something important.

Safety

Meta describes separately how the models were prepared for safety. They were trained not to share private information without permission and to refuse help with genuinely harmful actions, as well as to work on improving protection and countering cyberattacks. At the same time, the models are meant to help developers and security teams find vulnerabilities in their own code and strengthen their systems.

Muse Wonder is already available through the Meta Model API and the Muse Code environment. Later the models will also appear in the Muse assistant, starting with subscribers. Meta conducts the training, evaluation, and release of its most capable models under its Meta Superintelligence Scaling Framework, and a full report with additional safety evaluations is promised later. The company calls this release a step toward personal superintelligence for everyone.
