Amazon Research Led to White House Anthropic Ban

Amazon security research reportedly influenced the White House's decision to ban Anthropic's Fable 5 and Mythos 5 models for foreign nationals. This action followed cybersecurity research from Amazon, which indicated Fable 5 could provide information useful for cyberattacks. Amazon CEO Andy Jassy discussed these security concerns with the White House. What's interesting is that Anthropic disputes the characterization of this as a "jailbreak," stating similar vulnerabilities exist in other public models like GPT 5.5. Some security researchers support Anthropic's view. This directive also meant many of Anthropic's foreign-born researchers were blocked from their own product. This situation highlights ongoing tensions between the government and Anthropic.
