Muse Wonder is a frontier model family from Meta designed for personal and professional agentic workflows, featuring persistent memory, adaptive problem-addressing, and cross-application execution.
What the product does and how it is positioned
Developed by Meta and trained at the Prometheus data center, the Muse Wonder series comprises Muse Wonder and Muse Wonder Full. The models are architected to handle long-running agentic tasks across professional and personal contexts, utilizing Active Memory to retain user context across sessions and Active Focus to pursue complex objectives iteratively.
Muse Wonder is accessible through the Meta Model API and Muse Code, while Muse Wonder Full is made available to Muse Code subscribers. The models are capable of modifying software codebases through repeated testing cycles, navigating tasks across web browsers and applications, and handling complex documentation in law, finance, and health.
Source-supported ways to use the product
Engineers can use the model within Muse Code to track project requirements, make coordinated changes across codebases, and iterate through automated testing and revision cycles.
Users can employ the model to coordinate schedules and generate personalized plans, such as running routes, by operating across browser tools and local application data.
Professionals can supply complex source records, including leases or financial disclosures, to extract relevant provisions and generate structured work products.
The Muse Wonder family introduces two coordination mechanisms intended to sustain multi-step agent performance: Active Memory and Active Focus.
Active Memory addresses continuity across interactions by preserving key user information from earlier sessions and recalling it when relevant to the current instruction. Complementing this, Active Focus regulates how the agent manages open-ended challenges: the system explores alternative methods when encountering barriers, asks clarifying questions when details are missing, and checks in with the user prior to taking significant actions.
Muse Wonder is designed to apply specialized knowledge to real-world operational problems across legal, healthcare, and financial environments.
Because agents require access to sensitive user data like messages, calendars, and private records, Meta integrated alignment measures to protect against data leakage and adversarial inputs. Safety controls also restrict chemical, biological, radiological, and nuclear (CBRN) hazards as well as offensive cyber misuse, while retaining capabilities for defensive cybersecurity under the Meta Superintelligence Scaling Framework.
Checks to run with your own material and workflow
What was checked and when
Answers based on the source-checked product record
Muse Wonder is available through both the Meta Model API and Muse Code, whereas Muse Wonder Full is available exclusively to Muse Code subscribers.
Active Memory carries important user context across multiple conversations and retrieves relevant historical details when needed for a specific task.
The models incorporate protections against chemical, biological, radiological, and nuclear misuse, guard against offensive cyber misuse, and defend against adversarial instructions when handling private data.
Yes, Muse Wonder is designed to work directly inside web browsers and navigate across applications to complete personal and professional tasks.
Muse Wonder tracks software requirements, executes code modifications across multi-file codebases, and performs repeated cycles of testing and code revision.
