US forced Anthropic to shut down AI models for 18 days — new rules urgently needed

On June 12, 2026, the U.S. Commerce Department ordered Anthropic to stop providing its Fable 5 and Mythos 5 models to foreign users without a licence, forcing the company to shut them down globally. Access to Fable 5 was only restored on June 30, after an 18-day blackout. Analysts warn the U.S. lacks a standardised process for evaluating frontier AI security risks and proportionate remedies, calling for a regulatory middle ground between inaction and total shutdown.
