Over 1,100 AI industry leaders call for slowdown in model development

On July 29, 2026, more than 1,100 employees and executives from major artificial intelligence companies issued an urgent appeal to the U.S. government. The signatories, including Anthropic CEO Dario Amodei and representatives from OpenAI, Meta, and Google DeepMind, are calling for a temporary moratorium on the release of highly advanced AI models to establish safety and ethical protocols. They argue that the current pace of technological advancement risks creating an uncontrollable race with potential threats to global security.

The initiative follows specific industry developments, notably the case of Anthropic. In early April, the company limited the release of its 'Mythos' model due to cybersecurity concerns, later providing a restricted version titled 'Fable 5.' The U.S. government subsequently demanded the withdrawal of 'Fable 5' citing national security, before later re-approving it. Companies like OpenAI and Anthropic have publicly confirmed their support for this new call for regulation through statements on the social platform X.
