AI Leaders Urge Government to Slow Automated Development

Over 1,100 AI researchers and executives, including Anthropic CEO Dario Amodei and chief scientists from OpenAI and Meta, have signed an open letter calling for tools to deliberately pace automated AI model development. Signatories warn that AI-driven development could accelerate capabilities beyond human understanding or control. The letter requests U.S. government support for an international effort to develop technical and governance tools to manage this risk. It comes amid growing industry momentum around AI policy, with recent calls from Nvidia on open-source models, economists urging stronger regulation, and Google DeepMind CEO Demis Hassabis proposing a new AI standards body.
