Meta has unveiled two of its most advanced AI models, Muse Wonder and Muse Wonder Full, designed to power personal and professional AI agents. These models follow the launch of Muse Spark in April and the Muse personal AI agent in September. Meta claims that the development of these models began 14 months ago, with training taking place at its gigawatt-scale Prometheus data center.
Muse Wonder and Muse Wonder Full are marketed as powerful agents capable of handling tasks such as insurance claims, lease comprehension, and financial analysis. The company emphasizes two key features: Active Memory, which carries relevant context across conversations, and Active Focus, which keeps the model working on a difficult task by trying other approaches, recovering from errors, and checking in before taking important actions.
The models boast a 1 million-token context window and can process text, images, video, audio, and PDF inputs, with text output. Meta's new family of frontier models, Muse Wonder, features its strongest safeguards against misuse in areas like chemical, biological, radiological, nuclear, and cyber threats. According to Meta's own benchmark chart, the models are compared against Claude Opus 5.5, Claude Fable 5.1, and GPT-6 Astra.
Independent tester Artificial Analysis scored Muse Wonder Full at 56 on its Intelligence Index, tying Claude Sonnet 5.5 and outperforming GPT-6 Astra, Gemini 4 Argon, and Claude Fable 5.1. Only Claude Opus 5.5 scored higher, at 58.
Muse Wonder is currently available through the Meta Model API, Muse Code, and OpenRouter, with a price of $4 per million input tokens and $20 per million output tokens. Muse Wonder Full, however, does not have a public API and is only available to Muse Code subscribers on the $50-a-month Power and $200-a-month Maximum plans. Meta plans to integrate Wonder into its Muse app, initially rolling it out to subscribers and later using it to create specialized models for all Muse users.
