Google fuses Brain and DeepMind to take on OpenAI

Google is finally dropping the internal rivalry and putting all its AI muscle under one roof.

Faced with relentless pressure from Microsoft and OpenAI, Google announced that it is merging its two premier AI research groups—DeepMind and Google Research’s Brain team—into a single powerhouse unit dubbed Google DeepMind.

Demis Hassabis, co-founder and CEO of DeepMind, is taking the reins as CEO of the combined division. Hassabis stated that Google DeepMind will work closely across Google product areas to build AI breakthroughs and ship products faster.

Shuffling the deck

The merger brings a major reshuffling at the top.

Google Brain co-founder Jeff Dean is stepping into an elevated role as chief scientist for both Google Research and Google DeepMind, reporting directly to CEO Sundar Pichai.

Research direction, however, appears heavily anchored under DeepMind’s wing. Koray Kavukcuoglu, VP of research at DeepMind, will lead a newly created scientific board to oversee project directions. Zoubin Ghahramani, who headed Google Brain, will report to Kavukcuoglu as part of the research leadership team.

Meanwhile, Eli Collins, VP of product at Google Research, joins Google DeepMind as VP of product. What remains of Google Research will stay independent under James Manyika, focusing on core computing problems like quantum computing, algorithms, privacy, and climate sustainability.

Ending the civil war

Both teams have massive pedigrees.

Brain was formed in 2011 by Jeff Dean, Greg Corrado, and Andrew Ng, eventually producing TensorFlow and supercharging Google Translate. DeepMind, acquired in 2014 for $500 million, gave the world AlphaGo and the protein-folding breakthrough AlphaFold.

Yet the relationship between DeepMind and its parent company has often been complicated. DeepMind’s massive compute bills and 1,000-person headcount led Alphabet to write off roughly 1.1 billion pounds in debt in 2019. Management spent years pushing for legal independence, but those talks officially fell apart in May 2021.

What changed? The launch of ChatGPT and Microsoft’s Bing Chat lit a massive fire under Mountain View. Google’s own chatbot Bard debuted to lukewarm reviews, triggering a sharp stock drop.

Behind the scenes, the walls were already crumbling. Reports revealed that Brain and DeepMind engineers had already teamed up on Gemini, an upcoming model designed to directly challenge OpenAI. Meanwhile, Google has mobilized over 160 people to work on Magi, an AI-powered search initiative.

Why it matters

Google had no choice but to push the emergency button. For years, Alphabet enjoyed the luxury of letting two world-class AI labs operate in silos, publishing dueling papers and consuming dual compute budgets. In the generative AI era, that redundancy became an expensive handicap.

Putting Hassabis in charge signals a shift toward sharper execution and high-stakes product integration. However, merging DeepMind’s blue-sky research ethos with Brain’s infrastructure-heavy corporate DNA will not be seamless. Culture clashes and talent churn are real risks.

For the broader industry, the honeymoon phase of loose corporate research is officially over. Google is mobilizing for a full-scale platform war against OpenAI and Microsoft. Whether this consolidated giant can out-innovate a nimble competitor like OpenAI will largely depend on how fast Hassabis can turn Gemini into a reality.
