Eight years after joining Apple to reshape its approach to artificial intelligence, John Giannandrea is leaving the company entirely, a move that comes as his influence has steadily unraveled.
When CEO Tim Cook hired Giannandrea, the expectations were expansive. He was tasked with advancing core technologies like Siri while also contributing to ambitious initiatives such as the Apple Car. At the time, Cook framed the hire as a values-driven bet on the future of AI. “Our technology must be infused with the values we all hold dear,” he said. “John shares our commitment to privacy and our thoughtful approach as we make computers even smarter and more personal.”
But as the industry rapidly pivoted toward generative AI, Apple’s strategy began to look increasingly out of step.
According to Bloomberg, internal confidence in Giannandrea eroded following delays to long-promised upgrades to Siri and a disappointing rollout of Apple Intelligence. The company was also grappling with a broader perception that it had been slow to respond to the generative AI boom reshaping competitors.

That shift became unmistakable in March 2025, when Giannandrea lost control of Siri, arguably Apple’s most visible AI product. The responsibility was handed to Mike Rockwell, best known for his work on the Apple Vision Pro, who began reporting directly to software chief Craig Federighi. Behind the scenes, the decision signaled a deeper loss of confidence. Tim Cook and other senior executives had decided to significantly reduce Giannandrea’s role after concluding he was struggling to “execute on product development,” according to Bloomberg.
From there, the unraveling accelerated. Oversight of key AI divisions—including Siri, robotics, and broader machine learning efforts—was gradually redistributed across Apple’s leadership. Federighi took on a larger role in software-driven AI, while services head Eddy Cue and COO Sabih Khan absorbed other responsibilities.
By the time Apple formally announced Giannandrea’s retirement last December, the role he was hired to fill had effectively been dismantled. His remaining responsibilities, including foundation models and AI testing, were divided among those same executives, leaving no single leader at the center of Apple’s AI strategy.
Giannandrea’s final months followed a familiar Silicon Valley pattern of a “rest and vest” phase, Apple Insider reported. After stepping back into an advisory role, he remained on payroll as his stock continued to vest, a common practice for senior executives nearing departure. His exit aligns closely with Apple’s next vesting date in mid-April, marking a quiet end to a tenure that once carried heavy Apple’s AI ambitions.
