Trump administration restricts foreign access to Anthropic's most advanced AI models

Amazon tip-off led White House to force Anthropic to pull Fable 5 and Mythos 5 from foreign users

Financial Times — TechA jailbreak report Amazon filed Thursday night triggered a 90-minute White House ultimatum that forced Anthropic to disable Fable 5 and Mythos 5 for foreign nationals, with five other companies also raising concerns. A Commerce Department letter framed it as an export control directive; Anthropic called it a misunderstanding and flew senior technical staff to Washington to negotiate restoration while virtual meetings with officials began. Defense Secretary Hegseth said the DoD had ejected Anthropic from its building three months earlier. A later TechCrunch investigation found the ban was rooted in a policy dispute, not the jailbreak incident the initial reports described.
