tl;dr: Meta introduces Muse Wonder and Muse Wonder Full, frontier models aimed at personal and professional agentic tasks, available via the Meta Model API and Muse Code. The models emphasize "Active Memory" (retaining relevant user context) and "Active Focus" (sustained goal pursuit), claiming state-of-the-art results on benchmarks in domains like law, finance, health, and coding (including SWE-Marathon). Meta also highlights improved out-of-distribution generalization from stronger base models, and stronger safeguards against CBRN and cyber misuse under its Superintelligence Scaling Framework.
