Quick answer
Meta introduced Muse Wonder and Muse Wonder Full on October 12, 2026, describing them as models for personal and professional agent tasks. Meta highlights Active Memory for retrieving useful context across conversations and Active Focus for continuing through a difficult task, asking for clarification, and checking before important actions. The company says Muse Wonder is available through its Model API and Muse Code, while Wonder Full is for Muse Code subscribers; access in Meta's consumer Muse app is planned but not yet dated. Neither exact model is listed in Chat AI's public directory, so availability there is unverified.
Meta designed Muse Wonder for agent tasks that continue over time
Meta says Muse Wonder and Muse Wonder Full build on Muse Spark and are intended for personal and professional work, including understanding documents, coding, and tasks involving law, finance, and health information. The announcement highlights two capabilities: Active Memory, which retrieves relevant context across conversations, and Active Focus, which can try alternate approaches, work through blockers, request clarification, and check in before important actions. These describe Meta's design goals and evaluations, not a guarantee that an agent will complete every task correctly.

Meta says privacy and action safeguards are part of the release
Meta says the models were trained to avoid sharing private information without permission, refuse harmful requests, and check in before important actions. Its research overview also describes evaluations for memory, sustained work, and coding. Meta says a fuller report with additional safety evaluations will be available later, so the launch announcement is not a complete independent safety assessment. Review permissions and verify consequential actions when using any agent with access to personal data or connected tools.
