Meta released Muse Wonder and Muse Wonder Full, describing them as its most capable models for personal and professional agentic work.
Muse Wonder is available through the Meta Model API and Muse Code, while Muse Wonder Full is available to Muse Code subscribers.
The models combine Active Memory and Active Focus, and Meta states they lead across evaluations covering personal and professional agents, memory, sustained execution, coding, domain expertise, private-information handling, and resistance to misuse.
