Meta Releases Muse Wonder and Muse Wonder Full Models
Understand the story
On October 13, 2026, The Verge first reported that Meta released two new models, Muse Wonder and Muse Wonder Full, claiming they can rival top models such as OpenAI GPT-6 Astra, Claude Opus 5.5, and Claude Fable 5.1, based on internal test results on multiple industry benchmarks. Later the same day, TechCrunch reported that the two models were released by Meta Superintelligence Lab, Meta's first attempt at frontier models; according to Meta's model card tests, the two models' benchmark scores are on par with Fable 5.1 and GPT-6 Astra. The Decoder then reported that the two models scored 52 and 56 respectively on the Artificial Analysis Intelligence Index v4.3, versus 48 for the previous-generation Muse Spark 1.3, placing Meta in the front rank of models. Earlier that day, Simon Willison called them on his blog Meta's possibly first Fable-class models, updated the llm-meta-ai plugin to 0.2, and noted that Artificial Analysis rated Muse Wonder (Max) as equivalent to GPT-6.1 Sol. Later, Latent Space added that Muse Wonder, codenamed Watermelon, is the second-generation model family from Meta Superintelligence Labs, released just 6 weeks after Muse Spark 1.3, reaching the frontier about 14 months after MSL was founded. Some performance figures currently come from Meta internal tests or model cards, with third-party index scores serving as the main independent evaluation data.
