Introduction
While John Giannandrea leaves Apple after eight years, the company has already found its replacement. His name is Amar Subramanya – a 46-year-old, Bengaluru-born engineer who built Google’s Gemini AI assistant and then briefly led Microsoft’s Copilot foundation models. This new Apple AI chief brings over two decades of machine learning expertise at exactly the moment when Apple needs a builder, not just a strategist.

Who Is Amar Subramanya? A Quick Overview
Amar Subramanya is Apple’s new Vice President of Artificial Intelligence. He reports directly to Craig Federighi, Apple’s head of software engineering. His appointment, announced on December 1, 2025, signals a major strategic shift as Apple strengthens its AI leadership and accelerates Apple Intelligence after years of delays.
Tim Cook’s welcome message: “AI has long been central to Apple’s strategy, and we are pleased to welcome Amar to Craig’s leadership team and to bring his extraordinary AI expertise to Apple.”
Early Life and Education
Subramanya’s journey from Bangalore to Silicon Valley is remarkable. He earned a Bachelor of Engineering degree in Electrical, Electronics, and Communication Engineering from Bangalore University in 2001. He then moved to the United States, completing a PhD in Computer Science at the University of Washington in 2009, focusing on semi-supervised learning and graphical models. During his graduate studies, he was a visiting researcher at Microsoft Research and received a Microsoft Research Graduate Fellowship in 2007. He also co‑authored the book Graph‑Based Semi‑Supervised Learning, contributing research across natural language processing, entity resolution, and speech technologies.
Career Path: From IBM to Google to Microsoft to Apple
| Period | Company | Role |
|---|---|---|
| 2001 (10 months) | IBM | Software Engineer |
| 2005–2009 (PhD) | Microsoft Research | Visiting Researcher |
| 2009–2025 (16 years) | Staff Research Scientist → Principal Engineer → VP of Engineering → Head of Engineering for Gemini Assistant | |
| July 2025 – Dec 2025 (~5 months) | Microsoft | Corporate Vice President of AI (Foundation Models, Copilot) |
| December 2025 – present | Apple | Vice President of Artificial Intelligence |
16 Years at Google – Building Gemini
Subramanya spent 16 years at Google, starting as a Staff Research Scientist and rising to Vice President of Engineering. From 2023 onward, he was Head of Engineering for Google’s Gemini AI assistant, working closely with DeepMind. In this role, he led the engineering backbone of Google’s flagship generative AI product, which competes directly with OpenAI’s ChatGPT.
A Brief but Important Stop at Microsoft
In July 2025, Subramanya announced on LinkedIn that he had joined Microsoft as Corporate Vice President of AI, reporting to Mustafa Suleyman, the CEO of Microsoft AI. There, he helped oversee the foundation models behind Microsoft Copilot – the AI assistant integrated into Windows, Office, and Edge. His stay was short: less than five months later, Apple poached him for its own AI leadership role.
Why This Hiring Is a Coup for Apple
That Apple successfully recruited a top lieutenant from Microsoft’s aggressively assembled AI team is a significant coup. But the subtext is urgent: after years of Siri delays and Apple Intelligence stumbles, Tim Cook is not just replacing a retiring executive – he is calling in a builder to save Apple’s AI future. According to Bloomberg’s Mark Gurman, the move underscores how seriously Apple is now taking the AI race.

What Subramanya Will Do at Apple
As Apple’s Vice President of AI, Subramanya leads three critical areas:
- Apple Foundation Models – The in‑house large language models that will power next‑generation Siri and Apple Intelligence.
- Machine Learning Research – Advancing Apple’s capabilities in generative AI, on‑device processing, and multimodal models.
- AI Safety and Evaluation – Ensuring Apple’s AI systems remain private, secure, and aligned with the company’s values.
He reports directly to Craig Federighi, who oversees software engineering, including iOS, macOS, and Siri. Some of Giannandrea’s former duties (AI infrastructure, search) have been moved to COO Sabih Khan and services chief Eddy Cue, creating a more distributed AI governance structure.
