Amazon CEO reportedly raised Anthropic model concerns before government crackdown
Amazon CEO Andy Jassy reportedly raised security concerns about Anthropic's models to government officials, leading to an export control ban on two models, Claude Fable 5 and Mythos 5. The ban was imposed after Jassy allegedly informed Treasury Secretary Scott Bessent and other officials that Amazon researchers used the models to obtain information that could be used in cyberattacks. Anthropic has since cut off worldwide access to the models, affecting Amazon Web Services (AWS) and sparking controversy.
