Amazon CEO Andy Jassy reportedly warned the Trump administration about security risks in Anthropic’s advanced AI models. Amazon researchers discovered that the Fable 5 model could be manipulated to generate information for cyberattacks.
The U.S. government issued a directive to block foreign nationals from accessing Anthropic’s Fable 5 and Mythos 5 systems. Officials cited national security concerns following validation of the reported vulnerabilities.
Anthropic responded by disabling global access to both affected models. The company implemented the shutdown for all users in response to the government’s export control measures.
