Anthropic’s clash with the Trump administration and June 12 access curbs on Claude Mythos 5 and Fable 5 pushed some customers to Chinese open-source alternatives before Washington reversed the restrictions.
Anthropic’s dispute with the Trump administration broadened into a legal and political fight after the company was deemed a security risk earlier this year, reportedly after declining to give the Defense Department unfettered access to its tools. The conflict intensified on June 12, when U.S. export controls on Anthropic’s Claude Mythos 5 and Fable 5 models forced the company to cut off international access, disrupting foreign organizations and multinational clients and pushing some users toward Chinese open-source AI alternatives. The U.S. Department of Commerce later rescinded the restrictions after Anthropic added stronger security classifiers, and Commerce Secretary Howard Lutnick said a license is no longer required to distribute the models. Anthropic said global access would begin restoring on July 8, though analysts said the episode could still have lasting competitive effects by encouraging customers to adopt less restriction-prone alternatives.
