Meta Muse Wonder and Muse Wonder Full: Meta's First Frontier Models

Meta introduced Muse Wonder and Muse Wonder Full on October 12, 2026, calling them its most capable models to date. They build on Muse Spark, the model behind Meta's Muse personal agent, and target agentic tasks people actually hand off: working through an insurance claim, making sense of a lease, building a working app.

Wonder vs Wonder Full

• Muse Wonder is available to developers and builders through the Meta Model API and Muse Code, Meta's coding agent. Meta says it will soon power more of the Muse app, rolling out to subscribers first.
• Muse Wonder Full is the stronger variant and is only available to Muse Code subscribers. Reporting at launch put Muse Code's plans at $50 and $200 a month. Meta says Wonder Full tops agentic and coding benchmarks including DeepSWE and SWE-Marathon in independent third-party runs.

Who it is for

If you build agents, Wonder on the Meta Model API is a new option next to OpenAI's GPT-6.1 Sol and Anthropic's Claude Sonnet 5.5. If you code with an agent every day, Wonder Full inside Muse Code competes with Codex, Claude Code and Cursor. If you just use Meta's Muse app, the models arrive there over time.

Coding agents you can buy on PerkShelf

Muse Code is sold by Meta directly. For a coding agent today, Cursor Pro+ for a year ($399.99), Factory AI Pro ($89.99) and the Warp Build plan cover the three main styles: editor, autonomous agent and terminal. The coding agents comparison lines them up.

Is Muse Wonder the same as Muse?

No. Muse is Meta's personal agent app; Muse Wonder is the model family meant to power it and other agents.
