Amazon CEO Andy Jassy is reportedly at the center of security concerns that led AI developer Anthropic to suspend global access to two of its models last Friday.
According to The Wall Street Journal, Jassy informed Treasury Secretary Scott Bessent and other government officials that Amazon researchers had leveraged Anthropic’s Claude Fable 5 to extract information potentially useful for cyberattacks. This disclosure reportedly prompted the government to subsequently impose an export control ban on both the Fable 5 and Mythos 5 models.
An Amazon spokesperson, commenting to the WSJ, stated that while it is “not uncommon for governments to seek our counsel on potential security risks,” the company refrains from disclosing “the details of those discussions.”
Further reports from The Information and Reuters corroborated these accounts, indicating that Amazon, a significant investor in Anthropic, had indeed raised concerns regarding the security vulnerabilities within Anthropic’s models.
Adding another perspective to the unfolding situation, David Sacks — former AI czar for the Trump administration and current co-chair of the President’s Council of Advisors on Science and Technology — provided his own version of events. Sacks claimed that “a highly credible trusted partner of both Anthropic and the USG […] came forward with [information about] a jailbreak.”
Sacks further elaborated, stating, “The Admin asked [Anthropic CEO Dario Amodei] to fix the jailbreak or de-deploy the model. Dario refused.”
