Releases

Meta Superintelligence Lab released Muse Wonder and Muse Wonder Full, larger than Muse Spark and positioned as Meta's first frontier models. Meta says they score comparably to Fable 5.1 and GPT-6 Astra and lead on its MemoryBench continual-learning test (company claims). Muse Wonder costs $4 / $20 per million input/output tokens on the Meta Model API; Wonder Full is limited to Muse Code subscribers. Both power the Muse agent and were trained at the Prometheus data center in Ohio.
