Meta launches Muse Wonder models built to run AI agents
Meta says its two new models match the best from OpenAI and Anthropic on agent work, with the strongest one kept for paying coders.
Meta released two new AI models on Monday 12 October 2026, Muse Wonder and Muse Wonder Full, and calls them its most capable yet. Both are built for agents: assistants that carry out a task for you, such as planning a run or ordering custom merchandise, instead of only answering a question.
Meta gives them two new skills. Active Memory lets the model remember useful details about you between chats. Active Focus is meant for long jobs: when one approach fails, the model tries another, and it asks you before doing anything important.
Developers can use Muse Wonder through the Meta Model API (the way developers plug a model into their own software) and Muse Code, Meta’s coding tool. The stronger Full version is for Muse Code subscribers on $50 or $200 monthly plans, CNBC reports, and Meta AI chief Alexandr Wang told CNBC the API will be priced well below OpenAI and Anthropic.
On the Artificial Analysis Intelligence Index, a combined score of many model checks, Meta says Muse Wonder Full beats Claude Fable 5.1 and sits just below Claude Opus 5.5, Wired reports. Meta says a full safety report will follow.
For advertisers, Meta now sells both the social reach and a frontier agent model, and Muse subscribers are first in line to get it.
