Google's AI talent exodus: Shazeer to OpenAI, Jumper to Anthropic

Two high-profile departures in a single week underscored that top research talent — not chips or power — may be AI's scarcest resource. Noam Shazeer, Gemini co-lead and a VP of engineering, announced late Wednesday on X that he is leaving Google for OpenAI, less than two years after Google rehired him as part of a roughly $2.7 billion deal. Shazeer originally left Google in 2021 after a chatbot he built went unreleased. Then on Friday, John Jumper — the Nobel laureate who co-created AlphaFold, the breakthrough that predicted over 200 million protein structures — said after nearly nine years he would leave Google DeepMind for Anthropic.

The mechanics matter: these are not junior researchers but architects of the field. Evan Schlossman of SuRo Capital (an OpenAI investor) told MarketWatch that 'there are not many individuals that have the experience, the knowledge and the track record in really shaping and helping define where AI models and progress is going.' Demis Hassabis publicly thanked Jumper for 'an extraordinary partnership' over nine years, noting AlphaFold 'changed the world.'

Competitively, the moves crystallize a narrative that has been building on Reddit: an r/singularity thread (655 upvotes, 226 comments) argued DeepMind is 'struggling to compete' with Anthropic and OpenAI, with Gemini 3.5 Pro seen as not the step-change Google needs. Ethan Mollick added fuel, observing that the ship-cadence of products and models is rising at Anthropic and OpenAI 'but not for any other labs.' Anthropic's recruitment of Jumper — a structural-biology Nobelist — also signals an AI-for-science push to complement its coding-and-safety brand.

Watch next: whether retention packages and counter-offers escalate, and whether DeepMind's research output visibly slows as senior leaders depart for rivals.
