Apple AI Chief John Giannandrea to Exit Next Week After Eight-Year Tenure

Apple’s artificial intelligence leadership is set for a major transition as John Giannandrea, the company’s long-serving AI chief, will officially exit next week, bringing an end to an eight-year stint that shaped Apple’s machine learning and AI strategy.

Apple’s longtime AI chief John Giannandrea will step down next week as Amar Subramanya takes charge of the company’s AI division.

According to Apple’s official statement cited by NDTV Profit, his departure is linked to the April 15 stock vesting date, marking the final phase of an advisory role he had taken on after announcing retirement in 2025.

Who Is John Giannandrea?

John Giannandrea joined Apple in 2018 from Google, where he previously led major AI and search initiatives.

At Apple, he was responsible for:

• Siri development

• machine learning infrastructure

• AI research

• foundation models

• search and knowledge systems

• AI safety and infrastructure

His team played a central role in building Apple Foundation Models, the core AI systems powering the company’s latest intelligence features.

Why His Exit Matters

Giannandrea’s exit comes at a crucial time for Apple as the company is racing to strengthen its AI position amid growing competition from rivals like OpenAI, Google, and Microsoft.

His responsibilities had already been reduced in 2025 following:

• delays in major Siri upgrades

• mixed response to Apple Intelligence rollout

• leadership restructuring in AI division

This leadership shift signals Apple’s urgency to accelerate its AI roadmap.

Who Will Replace Him?

Apple has appointed Amar Subramanya as the new Vice President of AI.

Subramanya most recently served as Corporate Vice President of AI at Microsoft and previously spent 16 years at Google, where he worked on Gemini Assistant engineering.

He will now lead:

• AI research

• model development

• safety systems

• Siri intelligence upgrades

and will report directly to Craig Federighi, Apple’s software chief.

What This Means for Apple’s AI Future

This move could mark a major strategic reset for Apple’s AI ambitions.

Investors and tech analysts will closely watch how the new leadership handles:

• Siri modernization

• generative AI features

• on-device AI models

• privacy-first intelligence tools

The leadership change may also impact future announcements at upcoming Apple events and WWDC updates.
