Meta Superintelligence Labs (MSL)
The 2025 reboot: a superintelligence lab built around a $14.3B talent bet
Latest: Four divisions: TBD Lab, FAIR, Products & Applied Research, MSL Infra (Aug 2025 restructure)
Meta's umbrella AI organization formed June 30, 2025 after its $14.3B investment for 49% of Scale AI. Chief AI Officer Alexandr Wang leads frontier-model group TBD Lab; Nat Friedman leads Products and Applied Research; FAIR and MSL Infra complete the four divisions. MSL built the entire Muse model family that replaced Llama as Meta's frontier line.
Why it matters
MSL is the organization behind Meta's 2025-26 pivot from open Llama to the closed Muse Spark line, assembled through the $14.3B Scale AI deal and nine-figure hires. Its research arm and Model API now decide what Meta ships to three billion users and to developers.
