Muse Wonder

Muse Wonder is a frontier AI model series released by Meta on October 12, 2026, designed specifically for complex, long-running, and multi-step agentic tasks.

Key Features

The Muse Wonder series is built to function as an effective personal and professional assistant, capable of handling tasks that require reasoning, tool usage, and sustained effort. Its core capabilities include:

• Active Memory: Allows the model to carry relevant context across different conversations and retrieve specific details needed for a current task, reducing the need for users to repeat information.
• Active Focus: Designed to help the model persist through difficult tasks. It enables the AI to try different approaches, recover from errors, and ask for clarification when necessary, rather than giving up halfway through a multi-step process.
• Multimodal Capabilities: The model accepts text, images, video, audio, and PDF documents.
• Agentic Workflow: It can plan, delegate to sub-agents, call tools in parallel, and operate across various applications (including browsers and desktop/mobile apps) to complete tasks like building software, navigating insurance claims, or analyzing leases.
• Context Window: Features a 1M-token context window.

Model Variations

• Muse Wonder: The standard model available to developers and builders through the Meta Model API and within Meta's developer platform, Muse Code.
• Muse Wonder Full: A more capable, premium version of the model. It is reserved for subscribers of Muse Code and is not available via the general Meta Model API.

Meta positions the Muse Wonder series as a major step toward personal superintelligence, aiming to handle practical, real-world work across domains such as law, finance, health, and software engineering.
