Apple has formally announced that John Giannandrea, its Senior VP of Machine Learning and AI, is stepping down from his position. He will serve as an advisor to the company before retiring in the spring of 2026.
Giannandrea will not be directly replaced by a Senior VP role, but by a Vice President: Amar Subramanya. Subramanya was at Google for 16 years and made a name for himself as a prominent AI researcher. Just this summer, he joined Microsoft as Corporate VP of AI. Now, after just six months, he’s joining Apple.
Subramanya was a principal member of the team that created Gemini (released in 2023) and Imagen 3 at Google. In other words, after OpenAI caught the industry off guard with ChatGPT, he appears to have been instrumental in helping Google catch up. Now, he’s at Apple, where the same work is desperately needed.
Subramanya will report to Senior VP of Software Engineering Craig Frederighi. He will be responsible for leading Apple’s efforts in Apple Foundation Models, ML research, and AI Safety and Evaluation. Most of those who worked under Giannandrea’s group will now report to Eddy Cue, the Senior VP of Services.
Giannandrea was brought into Apple from Google back in 2018, when Apple’s biggest AI effort was the ill-fated Apple Car project. He and his team have been responsible for many of the advancements Apple has made in the field of AI and ML, but he is perhaps also to blame for Siri–Apple’s most visible and important AI product–falling far behind the state of the art.
Apple’s press release reads as though Giannandrea will step back from his role right away, staying on to advise during the transition, and will fully retire in the spring of 2026, which is when we expect Apple’s next-gen Siri to be released. That gives Apple several months to get this new AI organization in place and its leadership running well by the time it introduces the new Siri to over a billion users.
