The new models, Muse Wonder and Muse Wonder Full, are available for Muse Code subscribers starting today. Wonder can also be accessed through the Meta Model API, Meta said.
Meta says it eventually plans to power its Muse AI agent with Wonder, starting with subscribers, and will develop specialized models it “can bring to everyone using Muse.” It hasn’t shared specifics or provided a timeline for either.
The company says its new models can rival leading models from OpenAI and Anthropic, including GPT-6 Astra, Claude Opus 5.5, and Claude Fable 5.1, pointing to results from internal testing on several industry benchmarks. It’s unclear how they stack up against Google’s Gemini 4 Argon, whose capabilities are still coming into focus.
The launches are part of Meta’s aggressive push to reestablish itself as a major force in AI. The company has poured billions into talent and infrastructure and has been steadily expanding its AI lineup, including with image model Muse Image and a heavy focus on bringing useful AI agents to the masses through Muse.
