Amazon CEO Triggered Anthropic Model Security Crackdown

Amazon CEO Andy Jassy reportedly alerted Treasury Secretary Scott Bessent and other officials that Amazon researchers used Anthropic's Claude Fable 5 to obtain cyberattack-relevant information. The government subsequently imposed an export control ban on the Fable 5 and Mythos 5 models, forcing Anthropic to cut off worldwide access. Trump's former AI czar David Sacks claims a trusted partner flagged a jailbreak and the administration asked Anthropic CEO Dario Amodei to fix it or pull the model, but Amodei refused. Anthropic countered that the flagged capabilities are already available in other publicly accessible models.
