Tim Cook said of Subramanya’s joining Apple: “AI has long been central to Apple’s strategy, and we are pleased to welcome Amar to Craig’s executive team and bring his extraordinary AI expertise to Apple. “In addition to Amal’s expanded leadership and AI responsibilities, Craig has been instrumental in driving our AI efforts, including overseeing our efforts to bring personalized Siri to our users starting next year.”
These leadership moves will help Apple strengthen its ML and AI technologies to deliver better user experiences across its devices and services. Subramanya, who previously worked on Google’s Gemini Assistant, is expected to be able to integrate AI into Apple’s virtual assistant, Siri.
Apple had previously delayed the release of AI-powered Siri, which was promised in the iOS 18 software update. The company is currently expected to roll out AI-powered Siri in early 2026, likely in a future iOS 26 software update.
