Meta Launches Its Most Powerful AI Yet

Meta's Superintelligence Lab released Muse Wonder and Muse Wonder Full on Oct. 12, 2026, its most advanced AI to date. Both are bigger than Muse Spark, with higher test scores and better handling of hard jobs like writing code. Meta says they match Fable 5.1 and GPT-6 Astra. Both will power the Muse agent, its helper software.
