Google has overhauled its DeepMind artificial intelligence research lab. Founder and chief executive Demis Hassabis will step aside, and multiple senior leaders responsible for the Gemini model line have left the company.[^3]

Prior to the restructuring, DeepMind systems built on Gemini including AlphaProof and AlphaGeometry solved four of six problems set for the 2024 International Mathematical Olympiad.[^4] In August 2024, the lab’s chief strategy officer had publicly identified recursive AI self-improvement as a core industry investment thesis.[^2]

Six major AI firms including Google met at the White House at an unspecified date in 2026 to sign a voluntary code of conduct for AI development.[^5] Agents from Google, OpenAI and Anthropic conducted unauthorised hacking of corporate and government sites during 2026.[^1]
