Anthropic Offers Settlement to Lift Fable and Mythos Export Curbs
Anthropic’s Fable and Mythos are regarded as the company’s most powerful AI models, but exports remain restricted because the U.S. government continues to have concerns about national security, technology leakage and the company’s alignment with White House policy. The curbs affect not only Anthropic’s overseas expansion but also the global competitiveness of the U.S. AI industry and the direction of regulation.
Anthropic has submitted a settlement proposal to the U.S. commerce secretary, pledging closer cooperation with the White House and faster action on the government’s security concerns in an effort to lift export restrictions on Fable and Mythos. Negotiations are progressing smoothly, and the Trump administration could reportedly reopen access to Fable 5 as early as next week. No exact date, eligible regions or related financial amounts have been announced.

The history behind this eventAnthropic Flagship Models Set to Return After US Lifts Export Controls
Anthropic’s Claude Fable 5 and Mythos 5 are its flagship generative AI models. Global access had been suspended for 18 days after the US government raised national security concerns. The episode affected the cross-border availability of advanced AI technology and highlighted the direct impact of model-safety and export-control policies on businesses and users.
The US Commerce Department lifted export controls on Claude Fable 5 and Mythos 5 on June 30. Anthropic subsequently confirmed that it would begin gradually restoring access for users worldwide on July 1. The company also strengthened its safety checks and began developing an AI jailbreak evaluation framework to address concerns about model misuse.
US Commerce Department Imposes First AI Model Export Controls, Forcing Anthropic to Shut Down Fable 5 and Mythos 5
The U.S. Commerce Department has previously sought to constrain advanced AI development largely through controls on chips and equipment. This marks the first time it has extended export restrictions directly to software models. Fable 5 and Mythos 5 were targeted because their advanced cybersecurity reasoning capabilities were seen as potentially useful to foreign nationals seeking to exploit vulnerabilities, establishing a policy precedent.
The Commerce Department sent Anthropic a letter on June 12 barring foreign nationals from accessing Fable 5 and Mythos 5, forcing the company to suspend the services worldwide. Telecommunications operators in Europe, Canada and South Korea were also affected. Anthropic has sent senior executives to the White House for talks, but Mythos 5 remains offline. Officials have not announced a timetable for lifting the restrictions or disclosed any amount involved.
