According to Fortune, Apple announced that its AI chief, John Giannandrea, will retire in the spring of 2026 after joining the company in 2018. He will be replaced immediately by 46-year-old Amar Subramanya, a veteran with over two decades in machine learning. Subramanya just left Microsoft in July, where he was Corporate Vice President of AI working on Copilot, after a 16-year stint at Google where he eventually became head of engineering for the Gemini AI project. At Apple, he will report to software boss Craig Federighi and oversee Apple Foundation Models, ML research, and AI Safety. Giannandrea’s former responsibilities are being redistributed to COO Sabih Khan and services head Eddy Cue, and he will stay on as an advisor until his 2026 retirement.
The backup arrives, not a moment too soon
Look, this is a huge deal for Apple. The company has been taking heat—and I mean serious, sustained criticism—for seeming slow in the generative AI race. Siri feels ancient, and while Apple Intelligence promises on-device smarts, the public perception is that they’re playing catch-up to Google, Microsoft, and the pure-play AI firms. So bringing in Subramanya isn’t just a replacement; it’s a statement. They’re getting a guy who was in the trenches building Google’s flagship product (Gemini) and then immediately went to help run Microsoft’s AI push (Copilot). He’s seen both sides of the biggest AI war going. That’s invaluable intel for Apple.
What this means for the Apple ecosystem
For users and developers, the signal is clear: AI acceleration is the priority. Subramanya’s specific mandate over “Foundation Models” and “AI Safety” tells you where the focus is. Apple is doubling down on building the core tech that will power everything from a smarter Siri to AI features in Final Cut Pro. The reshuffling of Giannandrea’s old duties is also telling. Moving some operational bits to the COO and services chief frees up the new AI lead to focus purely on the technology and its integration. Basically, they’re streamlining for speed. The big question is, can Subramanya’s deep experience with massive, cloud-centric AI models at Google and Microsoft mesh with Apple’s very public commitment to on-device, privacy-focused processing? That’s the fascinating technical and philosophical clash he’ll have to navigate.
A smooth transition, or a culture shock?
Here’s the thing: Apple’s culture is famously insular. Bringing in a top exec from not one, but two of its arch-rivals is… unusual. It shows a level of urgency we don’t often see from Cupertino. The two-year advisory overlap with Giannandrea is classic Apple—it ensures institutional knowledge isn’t lost and gives Subramanya a long runway to learn the unique Apple way. But let’s be real. His resume is all about scaling huge AI systems for billions of users at other companies. That’s exactly the kind of firepower Apple needs right now. If anyone can bridge the gap between Apple’s integrated hardware-software ethos and the demands of modern foundation models, it’s someone with his specific cross-platform pedigree.

The bottom line
This is Tim Cook making his biggest, most explicit bet on AI since the Apple Intelligence reveal. They’re not just promoting from within; they’re going out and grabbing a proven general from the front lines of the industry’s biggest battles. It removes a major point of criticism—that Apple lacked top-tier AI leadership—overnight. Now, the pressure is squarely on Subramanya and Federighi’s team to deliver features that feel both powerful and distinctly Apple. The next two years, leading up to Giannandrea’s full retirement, will be the real test. But for the first time in a while, Apple’s AI future looks like it has a very clear, and very experienced, captain at the helm.
