The U.S. government has mandated Anthropic to terminate access to its AI models Fable 5 and Mythos 5 for all foreign entities, including those operating within the United States. The directive, issued Friday evening, cited unspecified national security concerns.

Anthropic confirmed compliance with the order but noted that the government did not provide detailed evidence or specific vulnerabilities in writing. According to the company, any concerns regarding potential security breaches were conveyed verbally and deemed minor, with similar loopholes reportedly accessible through other AI models.

Impact on Anthropic Operations

The immediate suspension of Fable 5 and Mythos 5 affects all customers, including Anthropic’s own employees. The company stated that while it is cooperating fully with the government, the lack of transparency surrounding the order raises questions about the scope and justification of the restrictions.

“The government did not provide specific details of its national security concern,” Anthropic said in a statement.

This move underscores growing tensions between tech firms and national security agencies over the control and use of advanced AI technologies. As the U.S. continues to prioritize domestic security in the face of evolving threats, companies like Anthropic are caught in a balancing act between innovation and compliance.
