Sundar Pichai’s August 12 staff memo formalized what an August 6 all-hands had already telegraphed: Demis Hassabis is stepping aside as CEO of Google DeepMind to become Alphabet’s chief scientist, and Koray Kavukcuoglu, his CTO of 13 years, is taking the SVP seat. The reshuffle lands at the exact moment Google’s rivals are shipping and Google isn’t.

Hassabis’s last frontier release, Gemini 3.1 Pro, went out in February 2026. Since then OpenAI has pushed GPT-5.6 and Anthropic has shipped Mythos, while the next flagship Gemini, expected as 3.5 Pro, has slipped by two months. Alphabet spent more than $90 billion on AI in 2025 and has roughly doubled that to about $190 billion this year. The market noticed the memo before it noticed the strategy: shares fell 4% on the news, though the stock is still up around 76% over the last twelve months.

The framing from Pichai is momentum. The Gemini app has crossed 950 million monthly users, Gemma downloads are past 900 million, and nearly 90% of Fortune 100 companies are on Gemini Enterprise. The framing from analysts is different. “feels like a move that is designed to adjust the focus of Google’s efforts away from academic projects and more toward a stronger focus on improving frontier performance and improving the toolset for developers,” said Ben Wood of CCS Insight. Morningstar’s Malik Ahmed Khan, Constellation’s Ray Wang, and Futurum’s Nick Patience read it similarly: a research house tilting toward a product house.

The talent ledger is unforgiving. John Jumper, Hassabis’s Nobel co-recipient for protein structure prediction, left earlier this year for Anthropic. Jeff Dean, Alphabet’s longtime chief scientist, is walking out to start a company. Sergey Brin already told hundreds of DeepMind employees at an April town hall to move faster. Lila Ibrahim and James Manyika remain in AI-adjacent roles, with Kent Walker handling policy.

DeepMind, acquired by Google in 2014, spent a decade as the lab that produced WaveNet, DQN, and Isomorphic Labs. The Kavukcuoglu era begins with a narrower mandate: ship Gemini 3.5, close the gap, and let the chief scientist worry about the Nobels.
