Hassabis Proposes U.S. Body to Test Advanced AI Before Release

Demis Hassabis proposed a U.S.-led body to test frontier models — the most powerful AI systems — before release, in a DeepMind Institute essay. Developers would voluntarily submit models up to 30 days early at first, with passing tests possibly required for U.S. launch later. It would write secret backup tests and could call for coordinated slowdown if needed.
