Meta Superintelligence Labs (MSL)

Rebuild the stack after Llama 4: closed frontier 'Muse' models with pretraining, RL and test-time scaling, a fast compute ramp, and consumer agents; open weights only for small distilled models. SemiAnalysis argues Meta is on track on data, talent and compute.

Headquarters

Pushes against
Meta's own earlier open-weights-first Llama strategy.
Now
Muse Spark (2026-04-08) lagged open models on many benchmarks per SemiAnalysis but improved quickly; Muse app topped the App Store in September. LeCun left in 2025-11. Meta reportedly hired 11+ ex-xAI staff since 2026-02.
