Meta has introduced Muse Wonder and Muse Wonder Full, two AI models it says are designed for personal and professional agent tasks, including coding and work that requires remembering context. Muse Wonder is available through Meta Model API and Muse Code; Muse Wonder Full is available to Muse Code subscribers. Broader Muse availability is planned, but independent validation and several rollout details are not provided in the announcement.
Meta has introduced Muse Wonder and Muse Wonder Full, two AI models the company says are built for complex personal and professional tasks, including coding and work that requires retaining context. Muse Wonder is available through the Meta Model API and Muse Code, while Muse Wonder Full is available to Muse Code subscribers; Meta says a wider rollout through its Muse product is planned.
Meta describes the models as its most capable to date and says they combine two features it calls Active Memory and Active Focus. Active Memory is intended to carry relevant information across conversations and retrieve it when a task calls for it. Active Focus refers to continuing work toward a goal, trying different approaches when blocked, adapting to new information and asking for clarification when needed. Meta says the system checks in before important actions.
The company says the models were developed through work on pretraining and reinforcement learning, and trained at its Prometheus data center. Meta reports strong results across evaluations of personal and professional agents, memory and coding, including tests in law, finance and health. It also cites Harvey’s Legal Agent Benchmark, FocusBench and SWE-Marathon. The announcement describes these evaluations but does not provide enough independent evidence to treat Meta’s performance characterizations as externally verified.
Meta says Muse Wonder is available now through its Model API and Muse Code, and that Muse Wonder Full is available to Muse Code subscribers. The company says Muse Wonder will soon power experiences in Muse, rolling out first to subscribers, and will be used for artifact generation and processes requiring more intelligence. Meta also says it plans to develop specialized models based on Muse Wonder for Muse users.
What Agent Memory Could Change
The announcement matters because it positions Meta’s models for tasks that extend beyond generating a single answer. An agent may need to track requirements, use tools, revise work and retain relevant details from earlier exchanges. If those capabilities work reliably, they could make AI more useful for activities such as software development, planning and interpreting documents. For readers, the immediate practical question is access: the described availability is currently limited to developer channels and Muse Code subscribers, with broader consumer access still forthcoming.
Meta’s claims about memory and sustained effort are also central to its proposed use of agents. A system that carries personal context across conversations could reduce repeated explanations, but it also makes questions about control, privacy and accuracy more consequential. The report does not explain the settings or safeguards governing stored information, nor does it establish how well the models perform in independent, real-world use. The promised capability is therefore distinct from a demonstrated outcome.

From Muse Spark to Wonder
Meta places the launch within an AI rebuilding effort it says began 14 months before the announcement. The company previously introduced Muse Spark and described a plan for predictable scaling. It presents Muse Wonder as a further step in that sequence, built on changes to both pretraining and reinforcement learning.
The report also addresses whether benchmark performance carries over to unfamiliar tasks. Meta says Muse Wonder Full performs better on out-of-distribution tasks than the trend suggested by Muse Spark 1.3’s in-distribution results. The company attributes that difference to stronger base models and says broader capability matters for agents facing combinations of goals, tools and constraints not covered by training. These are Meta’s interpretations of its own evaluations; the supplied material does not include independent replication.

Performance and Access Still Developing
The supplied announcement does not specify a publication date, pricing, geographic availability or a timetable for the wider Muse rollout. It also does not detail how Active Memory is controlled, what information may be retained, or what privacy and safety protections apply. Meta says the models perform at a state-of-the-art level, but the report’s evaluations are company-reported; independent testing and real-world reliability are not established here. It remains unclear how consistently the models will ask for clarification or pause before consequential actions across different applications.

Planned Muse Product Rollout
Meta says Muse Wonder will soon power experiences in Muse, with subscribers receiving access first. The company also plans to use it for artifact generation and other processes requiring greater intelligence, and to develop specialized models for Muse users. No launch date or detailed rollout schedule is included in the supplied report. The next concrete developments to watch are the start and scope of the Muse rollout, the features made available to subscribers, and independent evaluations of the models’ agent, memory and coding performance.
