Anthropic announced the directive publicly that night, stating it had to "abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance" . The blanket shutdown affected not just international users but also foreign nationals employed by Anthropic itself
. Fable 5 had been widely released for public use only days earlier, while Mythos 5 was a more advanced system restricted to a limited group of organizations
.
In response to the shutdown, Anthropic sent senior technical staff to the nation’s capital for a series of urgent meetings. Sources report that the team engaged in virtual discussions with White House officials over the weekend before traveling for in-person talks scheduled with the Department of Commerce on Monday, June 15 . The primary goal is clear: to settle the conflict and reach an agreement that would restore access to the company’s most sophisticated AI systems
.
As of the latest reports, the negotiations are ongoing and no deal has been reached. Neither Anthropic nor the White House has provided immediate public comments on the status of the discussions .
The directive was extraordinarily broad. It did not simply restrict exports to certain adversarial nations but applied a blanket ban on access for any foreign national anywhere in the world, including those residing legally in the U.S. on work visas . This created an immediate compliance problem for Anthropic, which concluded that it had no feasible way to verify the nationality of every user in real time. The only path to full compliance was a universal shutdown
.
The action has drawn sharp criticism from the cybersecurity community. A group of prominent security figures, including chief information security officers and executives from Adobe, Zoom, and Sophos, have called on the Trump administration to lift the restrictions. They argue that restricting access to the first publicly released Mythos-class model is actively harming cyber defenders at a critical moment, while potentially benefiting malicious actors who are not bound by export controls .
Analysts and commentators have framed the dispute as a pivotal test of how the U.S. government will regulate frontier AI. External criticism has described the move as effectively killing public access to Anthropic's latest model under a broad national-security rationale . The outcome of the Washington talks could set a major precedent for future government intervention in advanced AI deployment.
