Meta unveils Muse Wonder and Wonder Full AI models for its Muse platform

Meta rolled out two fresh AI models, named Muse Wonder and Muse Wonder Full, as part of its accelerated push in generative AI. The models are now offered to subscribers of the Muse Code service, with Wonder additionally reachable via the Meta Model API. According to Meta, internal testing shows the new models can match leading systems such as OpenAI's GPT-6 Astra and Anthropic's Claude Opus 5.5 and Claude Fable 5.1.

While the firm highlighted these results, it did not compare the models to Google's Gemini 4 Argon, whose capabilities remain under review. Meta intends to power its Muse AI agent with Wonder for subscribers first, and later expand specialized versions to all Muse users, but no specific schedule was disclosed. The releases follow earlier launches of Muse Spark and the Muse agent, underscoring Meta's commitment to re-establishing a strong AI presence.
