The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees. The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance. Access to all other Anthropic models will not be affected.
We received the directive from the government today at 5:21pm (ET). The letter did not provide specific details of its national security concern. Our understanding is that the government believes it has become aware of a method of bypassing, or “jailbreaking” Fable 5. We reviewed a demonstration of this specific technique being used to identify a small number of previously known, minor vulnerabilities. These vulnerabilities all appear relatively simple, and we have found that other publicly-available models are able to discover them as well without requiring a bypass.
We are complying with the government’s legal directive and are removing access to Fable 5 and Mythos 5 for all users. However, we disagree that the finding of a narrow potential jailbreak should be cause for recalling a commercial model deployed to hundreds of millions of people. If this standard was applied across the industry, we believe it would essentially halt all new model deployments for all frontier model providers.
As we have stated publicly, we believe the government should have the ability to block unsafe deployments, as part of a statutory process that is transparent, fair, clear, and grounded in technical facts. This action does not adhere to those principles.
We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible.

1984The Trump administration’s decision to halt all foreign use of Anthropic’s most capable AI models was prompted by conversations between Amazon AMZN -1.23%decrease; down pointing triangle Chief Executive Andy Jassy and U.S. officials including Treasury Secretary Scott Bessent, people familiar with the matter said.
Researchers at Amazon had used a series of prompts to get Anthropic’s Fable 5 model to provide them with information that could be used to aid cyberattacks and was supposed to be off limits, Jassy told the officials, according to people familiar with the matter. Tech industry executives have been in regular touch with the administration about the power of cutting-edge AI tools.
Shortly afterward, White House officials held a meeting to discuss how to respond and security researchers began testing Amazon’s claims. The group decided that the most direct way to address that risk was by preventing foreign governments, companies and individuals from accessing the tool, the people said. President Trump later signed off on the action for security reasons despite concerns about hindering innovation, a senior White House official said.
The administration had long felt that Anthropic, one of the leaders in America’s AI race, couldn’t be trusted to manage the security risks its new model presented. Friday’s call between some administration officials and Anthropic Chief Executive Dario Amodei reinforced that feeling, the people said.
Combined with a recent executive order giving security officials more oversight of models, and discussions about the government’s potentially taking equity stakes in AI companies, the moves show a dramatic increase in the control the administration is willing to exert over the industry, some analysts said.
“We are talking about a significant escalation in the politicization of AI and centralization of control over advanced computation in this country,” said Adam Thierer, a senior fellow at the R Street Institute think tank focused on technology and innovation.
Shutting down the top models could hold back Anthropic as it prepares for an initial public offering as soon as this fall if users turn to other models. It could also benefit competitors such as OpenAI, which has a powerful cyber model of its own that it is gradually offering to customers and discussing with the Trump administration.
