Amazon CEO Andy Jassy may have played a key role in raising security concerns that preceded Anthropic’s decision to cut off global access to two of its AI models on Friday, according to recent media reports.
The Wall Street Journal reported that Jassy told US Treasury Secretary Scott Bessent and other government officials that Amazon researchers had used Anthropic’s Claude Fable 5 model to obtain information that could potentially be used in cyberattacks.
Following these concerns, the US government reportedly imposed an export control ban on Anthropic’s Fable 5 and Mythos 5 models, leading the company to disable access to both models worldwide.
An Amazon spokesperson told The Wall Street Journal that it is “not uncommon for governments to seek our counsel on potential security risks,” while adding that the company does not share details of those discussions.
The Information and Reuters also reported that Amazon, which is a major investor in Anthropic, had communicated concerns about the security of Anthropic’s models.
David Sacks, Trump’s former AI czar and current co-chair of the President’s Council of Advisors on Science and Technology, offered a separate account of the discussions. He said that “a highly credible trusted partner of both Anthropic and the US government” had shared information about a jailbreak affecting the model.
According to Sacks, the administration asked Anthropic CEO Dario Amodei to fix the jailbreak or de-deploy the model, but Amodei refused.
The reports highlight the growing tension between leading AI companies, major cloud providers, and government regulators as concerns increase over the potential misuse of advanced AI models in cybersecurity threats.
The situation also underscores the complexity of Amazon’s relationship with Anthropic. Amazon is one of Anthropic’s largest investors, yet reports suggest it may have also raised concerns that contributed to government restrictions on some of the company’s most advanced models.
