[AINews] Meta Muse Wonder & Wonder Full: MSL’s Claude 5.5-tier Frontier Model
Meta's MSL launches Muse Wonder frontier models, reportedly matching Fable and Astra on benchmarks
“a much larger and more advanced class of models that brings us to the frontier.”
Meta Superintelligence Labs shipped Muse Wonder and Muse Wonder Full, its second-generation model family, just 14 months after the lab was founded. Third-party evals place Wonder Full near or at the frontier, reportedly beating Anthropic Fable and Google Astra on some benchmarks, at $4/M input and $20/M output with a 1M context window. The launch signals MSL has closed the gap with top frontier labs and positions Meta as a serious competitor in the agentic AI coding and personal-agent market.
