Top Tech Leaders Agree to Slow Down Powerful AI

OpenAI chief Sam Altman, Anthropic chief Dario Amodei, Google DeepMind cofounder Demis Hassabis and SpaceX head Elon Musk have loosely agreed to slow work on the most advanced AI, to 'pace the frontier.' The agreement partly backs Amodei's September 2026 plan for outside checkers, American lab rules and a worldwide slowdown deal.
