BlockBeats News, June 14th, according to sources familiar with the matter, the Trump administration has decided to prohibit foreign countries from using Anthropic's most powerful AI model. The trigger was a communication between Amazon CEO Andy Jassy and Treasury Secretary Bessemer and other U.S. officials. Jassy informed officials that Amazon researchers, through a series of cues, successfully induced Anthropic's Fable 5 model to provide information that should have been restricted and could be used for cyberattacks.

The White House subsequently held a meeting to discuss response measures, and security researchers validated Amazon's claims. Ultimately, the government decided to address the risk by blocking foreign governments, companies, and individuals from accessing the tool, a move approved by President Trump. The government has long believed that Anthropic has struggled to manage the security risks posed by its new models. In response, Anthropic stated that it would cut off all user access to Mythos and Fable to ensure compliance.
