How Apple Foundation Models (AFM) buys data
AFM 2025 report (Jul 2025): collected large text-image preference data to train a reward model; human graders disagree on 20-30% of pairs; 'internal and external' human eval, vendors unnamed. AFM v3 (Jun 2026) uses in-house human graders. Apple researchers (CHI 2026) collected 1,500 designer annotations from 21 internal designers to fine-tune UI-generation models - direct design-feedback data work.
Dec 2025: Giannandrea retired; Amar Subramanya (VP AI) under Craig Federighi runs AFM, ML research and safety; Zhifeng Chen leads the foundation-models team. Human grading appears in-house; HCI/UI research group in Seattle (Nichols, Barik, Swearngin).
