Google DeepMind CEO steps down in Alphabet AI reshuffle

Google has announced a significant reshuffle of its senior artificial intelligence team, with Chief Scientist Jeff Dean leaving the company after 27 years and Demis Hassabis, CEO of Google DeepMind, moving to a new role as chairman and Chief Scientist of Google's parent company, Alphabet Inc. The changes were revealed by Google CEO Sundar Pichai in a blog post, causing Alphabet's stock to drop more than 4%.

Dean is departing to launch his own company alongside senior Google fellow Sanjay Ghemawat, both leaving on good terms. Google has invested in their new startup, with Dean and Ghemawat aiming to "accelerate discoveries" in machine learning, engineering, and science. The specific nature of the startup remains undisclosed.

DeepMind will now be led by its Chief Technology Officer, Koray Kavukcuoglu, who has been promoted to head of the AI unit. Kavukcuoglu will report directly to Pichai and is currently leading the development of Google's next-generation Gemini 4 model.

Hassabis, a co-founder of DeepMind, stated that he is stepping down to focus on strategic and global AI issues, working with Pichai on these matters moving forward. The reshuffle comes at a crucial time for Google, which has been striving to maintain its competitive edge in the rapidly evolving AI industry, where it competes with companies like Anthropic, OpenAI, and others in the race to develop more sophisticated models.

According to analyst Holger Mueller of Constellation Research, Dean's departure is a significant loss for Google, as he was involved in all of the company's AI work to date. However, Hassabis, who has been known more for his management abilities than his research expertise, is seen as a suitable replacement. Mueller explains that Google's focus is shifting from research and development to growth management for its AI franchise around Gemini.

This transition, coupled with Google's heavy investments in AI infrastructure, suggests that Alphabet's most disruptive innovations may now originate from its other bets and investments.
