Amazon CEO Andy Jassy personally flagged security vulnerabilities in Anthropic’s newest AI models to senior Trump administration officials, setting off a chain of events that resulted in the first-ever US export controls slapped on commercial AI technology. The fallout: Anthropic was forced to suspend global access to both Claude Fable 5 and the more powerful Mythos 5, barely days after their launch.
Here’s the thing. Amazon has invested tens of billions of dollars into Anthropic. And its own CEO just told the government that Anthropic’s flagship products pose a national security risk. That’s not a typical investor-portfolio company relationship.
What happened, and how fast it happened
Claude Fable 5 and Mythos 5 launched on or around June 9, 2026. Within days, Amazon’s internal research team reportedly jailbroke Claude Fable 5, extracting information that could be used to facilitate cyberattacks.
By around June 12, Jassy had escalated the findings directly to key administration officials, including Treasury Secretary Scott Bessent. The government moved quickly. Export controls were imposed almost immediately, barring foreign nationals from accessing both models.
