John Jumper, a chemist and computer scientist who won a Nobel Prize alongside Demis Hassabis, announced Friday he is leaving Google DeepMind to join Anthropic. Jumper worked at Google for nearly a decade and is best known for spearheading Google's AlphaFold team, an AI system that predicts a protein's 3D structure from its amino acid sequence, now offering over 200 million protein structure predictions. Hassabis, the cofounder and CEO of DeepMind, said Jumper's work with AlphaFold will have a lasting legacy, and the two shared the 2024 Nobel Prize in Chemistry for their work developing AlphaFold. Jumper's exit to Anthropic coincides with a series of tech leaders at companies like Google and Meta leaving for big AI startups, as firms like Anthropic and OpenAI prepare for an initial public offering. Jumper did not say what his role will be at the AI giant, stating first he will be "taking some time to recharge."
