Trump Admin Forced Anthropic to Pull Claude Mythos and Fable 5 — The Untold Story of AI's Regulatory Wild West

Nearly a week ago, the Trump administration sent an export control directive to Anthropic, forcing the AI lab to pull its most advanced models—Claude Mythos and Fable 5—offline. After days of negotiations, the two sides remain at odds, with Anthropic insisting it violated no concrete procedures while the White House argues the company behaved recklessly. The dispute stems from two concerns: first, Anthropic shared Mythos with SK Telecom, a South Korean telecom giant the administration alleges has ties to China; second, Amazon CEO Andy Jassy raised worries to Treasury Secretary Scott Bessent that Fable 5’s guardrails could be circumvented via jailbreaking. Anthropic says it coordinated the Mythos rollout with US officials and revoked SK Telecom’s access immediately upon being asked, and that jailbreaking is an industry-wide probabilistic problem, not easily solved.

The saga underscores the Wild West state of American AI regulation. The Trump administration has repeatedly blocked formal guardrails, arguing they would hamper innovation against China. Now, without clear laws, it is making up rules in real time. The White House demanded Anthropic prohibit all foreign nationals from accessing the models, locking out its own employees and customers including Apple, Meta, and much of the Fortune 500—ironically hampering the very innovation the administration claims to protect. A former White House technology official described the approach as “slap-dash,” putting the AI industry in a quandary. No official statement has been released beyond a vague post on X from White House technology adviser David Sacks. The incident reveals that even without formal regulation, companies can face sudden, opaque enforcement from the executive branch.
