Amazon CEO Andy Jassy may have been responsible for the security concerns that led Anthropic to cut off worldwide access to two of its models on Friday.
The Wall Street Journal reported that Mr. Jassy told Treasury Secretary Scott Bessent and other government officials that Amazon researchers used Anthropic’s Claude Fable 5 to obtain information that could be used in a cyberattack. Subsequently, the government imposed an export control ban on the Fable 5 and Mythos 5 models.
An Amazon spokesperson told the Journal that “it is not uncommon for governments to seek our advice on potential security risks,” but the company did not disclose “the details of those discussions.”
The Information and Reuters similarly reported that Amazon (a major investor in Anthropic) shares concerns about the security of Anthropic’s models.
David Sachs, President Trump’s former AI czar and current co-chair of the President’s Science and Technology Advisory Council, offered his own explanation of the debate, claiming that “very reliable and trusted partners of both humanity and the U.S. government (…) have come forward with (information about) the jailbreak.”
Sachs added, “Administrator asked[Anthropic CEO Dario Amodei]to either fix the jailbreak or undeploy the model. Dario refused.”
