Meta launched Muse Wonder on October 12, 2026, introducing Muse Wonder and Muse Wonder Full as frontier-level models designed for agentic tasks—multi-step work performed on a user’s behalf. Muse Wonder is available to developers through the Meta Model API and will roll out first to subscribers in the Muse personal-assistant app.
Model Capabilities and Safety Features
Meta described Muse Wonder and Muse Wonder Full as its most capable models, built to deliver state-of-the-art performance on personal and professional agentic tasks such as navigating insurance claims, interpreting leases, and building applications. The models target expert domains including law, finance, health, coding, and software development.
The announcement highlighted two key features for sustained, complex work. Active Memory retains relevant information across conversations and retrieves it when needed. Active Focus enables the models to persist through difficult tasks by trying alternate approaches, recovering from errors, asking for clarification, and verifying before important actions.
Meta said both models were trained to avoid sharing private information without permission, refuse requests that could facilitate harmful acts, and strengthen defenses against cyberattacks. A more detailed safety report will be published later.
Developer Access, Rollout, and Market Context
Muse Wonder is accessible to developers via the Meta Model API and Muse Code, while Muse Wonder Full is limited to Muse Code subscribers. Meta said Muse Wonder will soon power experiences in the Muse app, initially rolling out to subscribers.
This distribution strategy combines broad developer access with a subscriber-first consumer rollout, positioning the models for direct monetization through API usage and paid subscriptions. Secondary reports cited subscription tiers of $20 and $100 per month for Muse access, though these prices were not confirmed in Meta’s announcement. Muse downloads reportedly reached 5 million within 22 days of the September 8 launch, with download momentum slowing.
Benchmark comparisons from secondary sources indicated near parity with Anthropic’s models. An independent Artificial Analysis index scored Muse Wonder Full at 56, Claude Opus 5.5 at 58, GPT-6 Astra at 53, and Muse Wonder at 52. These figures were not included in Meta’s official announcement and should be treated as external context.
The pace of the consumer rollout and the timing of the promised safety report will influence how quickly the new models contribute to developer revenues and subscriber growth.
