Muse Wonder Full Description
Muse Wonder Full is a frontier AI model developed by Meta to support advanced reasoning, personal assistance, professional workflows, and autonomous software development. It is the larger model variant in the Muse Wonder series, which also includes the standard Muse Wonder model. The system combines Active Memory and Active Focus to maintain relevant context and sustain progress on complex assignments. Active Memory enables the model to preserve important information across conversations and retrieve details relevant to current objectives. Active Focus supports multistep execution by allowing the model to investigate alternative solutions, respond to obstacles, and adjust its approach as tasks evolve. Muse Wonder Full can assist with legal document analysis, financial reasoning, health-related information, and other knowledge-intensive activities. Its software engineering capabilities support code generation, application development, debugging, testing, and modifications across existing codebases. Meta has evaluated the model using benchmarks such as MemoryBench, FocusBench, SWE-Marathon, DeepSWE, and professional agent assessments. Muse Wonder Full is accessible through Muse Code subscriptions and is intended for tasks that require extended reasoning, contextual continuity, and coordinated AI agent execution.

Super frontier model from Meta Date: Oct 12 2026
Summary: Overall, Muse Wonder Full feels like Meta’s true frontier model. It is the version I would use when the task is hard enough that reliability, coding strength, memory, and long-horizon execution matter more than speed or cost.
Positive: I can give it a big coding or research task and it does a better job staying focused, recovering when something goes wrong, and actually finishing the job instead of stopping halfway through.
Negative: The downside is access. Right now Wonder Full is limited to Muse Code subscribers rather than being broadly available through the Meta Model API, so it is harder to plug directly into custom apps and agent stacks.
