Trump administration export control directive forced Anthropic to pull

An export control directive from the Trump administration has forced Anthropic to pull its most advanced models, Claude Mythos and Fable 5, offline. Negotiations between Anthropic and the White House remain at odds over conditions for bringing the models back, marking a transition into an era of ad-hoc AI licensing.

The crackdown was triggered by two factors: US officials discovered Anthropic had shared Mythos with South Korean giant SK Telecom, which they allege has ties to China, and Amazon CEO Andy Jassy raised concerns to Treasury Secretary Scott Bessent that Fable 5's safety guardrails could be bypassed via jailbreaking.

The directive forced Anthropic to block all foreign nationals from accessing the models, locking out its own foreign employees and major enterprise clients like Apple and Meta. Cohere CEO Aidan Gomez noted that AI labs must now expect to provide "advance notice, advance access" to governments to avoid similar abrupt actions.
