Apple AI chief steps down amid Siri struggles

Apple AI chief John Giannandrea is stepping down from his position, according to an announcement on Monday. The change comes as Apple struggles to get the launch of its AI-powered Siri back on track after delaying its launch earlier this year.

Now, Apple is appointing Amar Subramanya as its vice president of AI. Subramanya spent more than a decade at Google before joining Microsoft as the corporate VP of AI in July. He’ll oversee the development of Apple’s AI models, machine learning research, and AI safety and evaluation. Meanwhile, Giannandrea will continue working as an advisor before retiring in the spring of 2026.

After pushing back the release of an upgraded Siri in March, Bloomberg reported that Apple put Vision Pro leader Mike Rockwell in charge of AI and Siri, replacing Giannandrea. Apple CEO Tim Cook has since said that the company expects to release the upgraded version of Siri next year.
