A New Step in Meta's AI Push

Meta has announced two new AI models, Muse Wonder and Muse Wonder Full, calling them the company's most capable models to date 1. The models were designed for personal and professional AI agent tasks — things like navigating an insurance claim, understanding a lease, or building a working app.

The announcement comes 14 months after Meta began overhauling its AI efforts from the ground up. The company previously launched Muse Spark, the first model from its revamped Superintelligence Labs division, and introduced its popular Muse AI agent earlier this year 3.

What Makes Them Different

Both models are built with two key features Meta says are essential for real-world agents. Active Memory lets the model carry important details across conversations, remembering what matters to you over time. Active Focus helps the model stay on task when things get difficult — it can try different approaches, recover from errors, and ask for clarification before taking important action 2.

The models also cover expert domains including law, finance, and health, alongside strong coding abilities for people building games, apps, or new businesses 2.

How They Compare

Meta says the new models can rival leading AI systems from other companies. The company pointed to internal test results comparing Muse Wonder against models like GPT-6 Astra, Claude Opus 5.5, and Claude Fable 5.1 1. Meta has not released the full benchmark data publicly yet, and it remains unclear how the models compare to Google's Gemini 4 Argon, whose capabilities are still being tested by the industry .

The models were trained at Meta's gigawatt-scale Prometheus data center, part of the company's ongoing push to catch up in the AI race after falling behind rivals in recent years 3.

Where to Find Them

Muse Wonder is available today through the Meta Model API and Muse Code. Muse Wonder Full is available right now for Muse Code subscribers 3. Meta says Muse Wonder will soon start powering experiences inside the Muse agent, rolling out first to subscribers, though the company has not shared a specific timeline 1.

Meta also plans to develop specialized models in the future using Muse Wonder as a foundation, which could bring more advanced features to all Muse users 1. The company says a full safety report will be available soon, noting the models were trained and evaluated according to its Superintelligence Scaling Framework 2.
