The U.S. government ordered Anthropic to block foreign nationals from accessing its Fable 5 and Mythos 5 AI models. This directive cites national security risks associated with the company's most advanced technology.

Amazon CEO Andy Jassy reportedly triggered the order by warning the Trump administration that these models could facilitate cyberattacks. Jassy expressed concerns that users could jailbreak the software to generate malicious information.

Anthropic suspended access to both models for all users to ensure full compliance with the export control directive. The company described the situation as a misunderstanding and is currently working to restore access.

This move represents a significant escalation in federal AI oversight. U.S. policy is shifting from restricting hardware exports to exerting direct control over specific AI models.
