Apple reshapes AI leadership as John Giannandrea retires and ex‑Google/Microsoft researcher Amar Subramanya takes over

Apple has announced that long‑time AI chief John Giannandrea will step down from his role as Senior Vice President for Machine Learning and AI Strategy and move into an advisory position before retiring in spring 2026. He is being replaced by Amar Subramanya, a veteran AI researcher who previously led engineering for Google’s Gemini assistant and most recently served as corporate VP of AI at Microsoft; Subramanya becomes vice president of AI, reporting to software chief Craig Federighi and overseeing Apple Foundation Models, ML research, and AI safety and evaluation—part of a broader effort to accelerate Apple’s lagging generative‑AI push and a delayed, more capable Siri.
