Shapes what 'good data' means.
How Meta (Meta Superintelligence Labs) buys data
Aug 2025: TBD Lab researchers reportedly preferred Surge and Mercor data over Scale's, despite Meta's $14.3B Scale stake. Meta has also partnered with Mercor on RL environments (TechCrunch, Sep 2025). In Aug 2025 Meta licensed Midjourney's 'aesthetic technology' to make its models 'more visually appealing', which is a direct signal of paying for visual taste. Muse Image/Video (Jul 2026) are marketed on human-preference Elo from internal ablations and Arena. SemiAnalysis (Jul 2026) reports about 3,000 engineers working on RL task/environment creation.
Alexandr Wang (Chief AI Officer, org context only) heads MSL. Since Aug 2025 it has four parts: TBD Lab (frontier models), FAIR (Rob Fergus), Products and Applied Research (Nat Friedman) and MSL Infra (Aparna Ramani, Amir Frenkel). Shengjia Zhao is Chief Scientist and owns the Muse roadmap; Jiahui Yu leads multimodal, including Muse Image/Video. No human-data owner is public; data-vendor decisions appear to sit with TBD Lab researchers and ex-Scale staff.
Known vendors: scale-ai, surge-ai, mercor, lmarena, Midjourney (aesthetics tech licence)
