Meta has introduced two AI models, Muse Wonder and Muse Wonder Full, as it expands the technology behind its Muse products. The company says the models can match leading systems, and plans to use Wonder in its Muse AI agent, starting with subscribers.
Where the models are available
Muse Wonder and Muse Wonder Full are available to Muse Code subscribers. Meta also says Wonder can be accessed through the Meta Model API, giving developers another way to use the model.
The release links Meta’s model work with products aimed at both developers and users. Muse Code subscribers can try the models directly, while API access offers a route to incorporate Wonder into other software.
Meta’s claims about performance
Meta says the new models can compete with leading models from OpenAI and Anthropic. Its comparisons include GPT-6 Astra, Claude Opus 5.5, and Claude Fable 5.1, based on internal testing across several industry benchmarks.
Those results reflect Meta’s own testing. The article does not provide the benchmark scores, so readers cannot assess the size of any differences from the information provided. It also remains unclear how the models compare with Google’s Gemini 4 Argon, whose capabilities are still coming into focus.
The distinction matters: a claim of competitive performance signals Meta’s ambitions, but the information here does not establish how the models perform across particular tasks or in everyday use.
Wonder’s planned role in Muse
Meta says it eventually intends to power its Muse AI agent with Wonder, beginning with subscribers. The company also says it plans to develop specialized models that it “can bring to everyone using Muse.”
Meta has not shared details about those specialized models or a timeline for either plan. For now, the connection between Wonder and Muse is a stated direction rather than a fully described rollout. Subscribers may be the first group to see the agent use the model, while broader access depends on future development.
A wider effort to build Meta’s AI lineup
The new models are part of Meta’s push to reestablish itself as a major force in AI. The company has invested billions in talent and infrastructure and has been expanding its product range.
That lineup includes Muse Image and a focus on bringing AI agents to a broad audience through Muse. Wonder and Wonder Full add language models to that effort, with one model also offered through an API and both available to Muse Code subscribers.
The launch therefore combines a product release with a competitive claim and a longer-term plan. The models are available to some users now, while their eventual role in Muse and their standing against competitors will become clearer as more details and evidence emerge.
