Nobel-winning scientist John Jumper departed Google DeepMind to join competitor Anthropic. Jumper previously led the AlphaFold team responsible for AI protein structure prediction.

His exit follows the departure of Gemini co-lead Noam Shazeer to OpenAI earlier this week. These consecutive moves increase scrutiny on Alphabet’s ability to retain top researchers during an intense industry talent war.

The loss of these influential figures may impact the development of Google’s primary AI projects. Alphabet continues to face mounting pressure from rivals including OpenAI and Anthropic.
