Key points
- Muse Wonder and Muse Wonder Full were announced on October 12, 2026
- Muse Wonder is available to developers through the Meta Model API and Muse Code
- Muse Wonder Full is limited to Muse Code subscribers for now
- Both add Active Memory and Active Focus for long, multi-step tasks
Meta has released Muse Wonder and Muse Wonder Full, the newest models from Meta Superintelligence Labs (MSL), the AI group Meta set up to build its most advanced systems. Meta calls them frontier models for agents: AI that doesn't just answer a question, but works through a task step by step.
They build on Muse Spark, MSL's first large language model, which already powers the Meta AI assistant.
Who can use Muse Wonder?
- Muse Wonder is available to developers through the Meta Model API and in Muse Code, Meta's coding product.
- Muse Wonder Full, the larger version, is limited to Muse Code subscribers.
Meta says both models will soon power experiences in Muse, its personal AI agent, starting with subscribers. Regular Meta AI users in WhatsApp, Instagram and Facebook don't get them yet.
What's different about these models
Meta highlights two features for long tasks:
- Active Memory carries relevant context from one conversation to the next, so you don't have to repeat yourself.
- Active Focus helps the model keep working toward a goal when a task gets difficult, instead of giving up or drifting.
These are the abilities an agent needs to, for example, research a topic across many sources or fix a bug that touches several files.
What about safety?
Meta says it trained the Muse Wonder family to avoid sharing private information without permission and to decline requests that could cause real harm. It also says the models can still help security teams find flaws in their own code.
So far, the performance claims come from Meta itself. We haven't seen independent tests of Muse Wonder yet, and we'll update this article when they appear.
How it fits Meta's plans
Muse Wonder is the latest in a fast run of MSL releases this year: Muse Spark for Meta AI, Muse Image for image generation in July, and a preview of Muse Video. With Muse Wonder, Meta is now competing directly with OpenAI, Google and Anthropic for developers who build AI agents.
What it means for you
- Developers can try Muse Wonder now through the Meta Model API.
- Everyone else will meet these models later, inside Meta's Muse agent, starting with paying subscribers.
