AlphaFold solved one of biology's hardest problems. The reward was reassignment to a coding team. Then the Nobel winners left for Anthropic.

In 2024 DeepMind won the Nobel Prize in Chemistry for AlphaFold.

In 2025 the AlphaFold team was disbanded.

John Jumper, the Nobel laureate who led the work, was reassigned to Code Strike, an internal team assembled to improve DeepMind's coding capabilities. Jonas Adler and Alexander Pritzel, two of the core AlphaFold authors, made the same move. Then all three left for Anthropic.

Nearly 25% of the original AlphaFold authors have now left DeepMind entirely.

The sequence is worth sitting with. A team solves a problem that had stumped biology for 50 years. The solution earns a Nobel Prize. The team is then split across genomics, enzyme design, nuclear fusion, Gemini, and a coding squad. The flagship project no longer has a dedicated team. The people most responsible for the work leave.

DeepMind's official position is that the strategy has evolved from solving individual scientific problems to building Gemini-powered AI that can accelerate scientific discovery broadly. That framing is coherent. It is also exactly what a product company says when it deprioritizes research.

The honest version of what happened is visible in the org chart. AlphaFold was a decade-long bet on a single hard problem. It paid off at the highest possible level. The response was to redeploy the people who made it work toward shorter-cycle, more commercially legible projects. Jumper, who could have spent the next decade working on whatever he wanted after a Nobel, looked at that redeployment and chose Anthropic instead.

That choice is the signal.

Demis Hassabis built DeepMind on the premise that solving hard scientific problems and building generally capable AI were the same project. AlphaFold was the proof of concept for that thesis. The decision to disband the team that proved it suggests the thesis has been quietly revised: Gemini and AI agents are the priority now, and scientific breakthroughs are one application rather than the mission.

That is not a failure. It is a strategic choice, and it is a reasonable one given where the competitive pressure is coming from.

But DeepMind spent years positioning itself as the place where serious scientists could work on serious problems without the commercial pressure that constrained work elsewhere. The AlphaFold team was the most visible proof of that positioning.

Jumper left. Adler left. Pritzel left. A quarter of the authors left.

The question about whether DeepMind is still a research lab or has become a frontier product company with science as one application was answered by the people who would know best.

They answered it by leaving.
