In a press release on their “Newsroom” webpage, Apple announced that John Giannandrea, Senior Vice President of Machine Learning and AI Strategy, is set to retire in the Spring of 2026:

Apple today announced John Giannandrea, Apple’s senior vice president for Machine Learning and AI Strategy, is stepping down from his position and will serve as an advisor to the company before retiring in the spring of 2026. Apple also announced that renowned AI researcher Amar Subramanya has joined Apple as vice president of AI, reporting to Craig Federighi. Subramanya will be leading critical areas, including Apple Foundation Models, ML research, and AI Safety and Evaluation. The balance of Giannandrea’s organization will shift to Sabih Khan and Eddy Cue to align closer with similar organizations.

Taking Giannandrea’s place will be Amar Subramanya, who is currently CVP of AI at Microsoft and, prior to that, served in various roles at Google for 16 years, including VP of Engineering (where he worked on Google’s Gemini product).

Given that Siri and Apple’s AI efforts are seen as being behind other AI products like Gemini or ChatGPT, this move may not be surprising to some. However, it will be interesting to see how this change affects the state of Siri and AI at Apple going forward.
