US Commerce Department Lifts Export Restrictions on Anthropic AI Models

Anthropic announced overnight that the US Commerce Department has removed export restrictions on its AI models Claude Fable 5 and Mythos 5, ending a tense standoff between the company and the Trump administration. The restrictions had been imposed in mid-June shortly after the public launch of Fable 5, citing national security concerns. These limitations barred access to the models for all foreign nationals, including Anthropic employees with foreign citizenship, both inside and outside the United States.

The US government’s concerns reportedly involved the potential for users to bypass certain protective mechanisms in the models, which could enable advanced cybersecurity exploits or software vulnerability detection. Anthropic expressed gratitude to its users for their patience and to those who helped redeploy the models following the lifting of restrictions.

This announcement follows a recent partial approval by US Commerce Secretary Howard Lutnick, who authorized limited distribution of Mythos 5 to select companies and federal agencies. The restrictions on Anthropic coincided with rapid development of Chinese open-source AI models that offer similar capabilities at significantly lower costs, raising fears among US tech leaders that China might gain a critical lead in AI development during the export ban.

Anthropic’s situation highlights the growing tensions in AI technology control between the US and China, as well as the challenges of balancing national security with innovation and global competition.
