The Lead
Amazon CEO Andy Jassy may have been the source of security concerns that led Anthropic to cut off worldwide access to two models on Friday.
Amazon's Reported Security Concerns
The Wall Street Journal reports that 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 cyberattacks.
The Government's Response
The government subsequently imposed an export control ban on the Fable 5 and Mythos 5 models. An Amazon spokesperson said in a statement that while it’s “not uncommon for governments to seek our counsel on potential security risks,” the company does not “share the details of those discussions.”
The Impact on Anthropic and AWS
The Information and Reuters similarly reported that Amazon (a major Anthropic investor) had communicated concerns about the security of Anthropic’s models. An update stated that AWS has been affected by the model cut off.
Additional Insights
David Sacks, Trump’s former AI czar, claimed that “a highly credible trusted partner of both Anthropic and the USG […] came forward with a jailbreak.”
Sacks added, “The Admin asked [Anthropic CEO Dario Amodei] to fix the jailbreak or de-deploy the model. Dario refused.”
Anthropic's Response
Anthropic said in a blog post that the capabilities apparently causing government concern are already available in other publicly accessible models.
