Giannandrea held the position of senior vice president at Apple and reported to CEO Tim Cook. Apple announced that he will remain as an advisor until he retires in the coming spring.

Experts have stated this year that Apple has lagged behind its technology counterparts in artificial intelligence, a field that saw a resurgence with the launch of ChatGPT by OpenAI in 2022.

Apple Intelligence was expected to compete with leaders in artificial intelligence such as OpenAI and Google. However, it has received negative reviews from both users and critics.

This year, the key aspect of Apple Intelligence, which is a greatly enhanced Siri assistant, faced delays and is now expected to be released in 2026. This delay indicates that there have been challenges in the development process.

Apple has stated that Subramanya will take on the role of vice president of AI and will be reporting to software chief Craig Federighi. Cook mentioned in a statement that Federighi is already making substantial contributions to Apple's artificial intelligence projects.

“In addition to growing his leadership team and AI responsibilities with Amar’s joining, Craig has been instrumental in driving our AI efforts, including overseeing our work to bring a more personalized Siri to users next year,” Cook said.

 

Subramanya will be in charge of teams focusing on Apple's fundamental models, research, and AI safety. Apple has announced that the teams previously reporting to Giannandrea will now report to COO Sabih Khan and services chief Eddy Cue.
