Apple says AI chief John Giannandrea is stepping down and will retire in spring 2026; ex-Microsoft CVP Amar Subramanya takes over, reporting to Craig Federighi

Apple AI chief John Giannandrea is stepping down from his position and retiring in spring 2026, Apple announced today.

MacRumors 2025-12-02 Juli Clover

Context & Ripple Effects

Giannandrea’s appointment began with Apple’s 2018 effort to combine its machine-learning, AI, and Siri teams under a single leader, followed by a promotion to the executive team. His remit later expanded to include Project Titan, making this a consequential change in the ownership of Apple’s AI agenda.

The transition follows reporting that Cook had moved Siri oversight away from Giannandrea amid concerns about product execution. Putting Amar Subramanya under Craig Federighi formalizes a leadership structure in which AI is more closely connected to Apple’s software organization.

First-order effects

John Giannandrea will leave Apple in spring 2026, ending the tenure of the executive who led its machine-learning and AI strategy for most of the past eight years.
Amar Subramanya assumes the AI leadership role and reports to Craig Federighi, giving Federighi direct organizational oversight of Apple’s AI work.

Second-order effects

AI priorities and delivery decisions can be coordinated more directly with the software organization that Federighi leads, particularly after the earlier reassignment of Siri oversight.
The handoff creates a near-term test for Apple AI’s continuity: Subramanya inherits an established organization, while Giannandrea remains through the transition period.

Third-order effects

If this reporting structure persists, Apple’s AI effort is likely to be managed less as a standalone research-and-strategy function and more as a product-execution responsibility within core software leadership.
The move reflects the broader industrialization of AI: major platforms increasingly treat AI leadership as accountable for integrating capabilities into shipping products, not only for advancing research.

The trend: AI leadership is shifting toward product organizations as platform companies prioritize execution, integration, and clear operational accountability.

Yesterday, 20 mins in: “Who is in charge of AI? Right now it's been John Giannandrea... it sort of feels like the writings on the wall there. That he will probably not be there for very much longer.” Didn't expect “very much longer” to be a few hours... https://www.youtube.com/..…

Strange hire for a number of reasons but it's hard to argue the Apple job is a bad one. Anything is an improvement at this point so the bar is as low as it comes. Easy layup on the resume.

Speaks volumes that they needed to do a newsroom post for this with the departure and not the hire as the headline. https://www.apple.com/...

Three takeaways from the news...1. The new Siri is likely on track for a spring release... 2. He most likely was asked to retire...3. They want more from AI. The new head of Apple AI, Amar Subramanya most recently was a VP of AI at Microsoft, and previously at Google for 16 y…
