The US government has banned Anthropic's Fable 5, citing cybersecurity risks uncovered by Amazon's security research. Amazon found that through a series of prompts, Fable 5 could provide information usable in cyberattacks. Following a conversation between Amazon CEO Andy Jassy and the White House, an export control directive was issued, blocking foreign nationals from accessing the product. This move has significant implications for Anthropic, as many of its researchers are foreign-born and are now barred from working with their own product. Anthropic has disputed the government's characterization of the issue as a 'jailbreak', arguing that similar vulnerabilities can be discovered using other publicly available models. The company's stance is supported by some security researchers, who agree that the issue is not a 'jailbreak'. The situation highlights the complex interplay between technology, security, and international collaboration.
