Anthropic says US has lifted export controls on Fable and Mythos AI models after security fears
Anthropic has restored access to its Fable and Mythos AI models after the US government lifted export controls that had blocked foreign nationals from using them for over two weeks. The restrictions were put in place over fears the models could be exploited to enable serious cyberattacks.
Why this matters: This is a case of the government pulling a kill switch on a commercial AI product and then quietly flipping it back on. Foreign nationals lost access to a major AI model with little public explanation and no clear appeals process. The concern about cyberattack risk is real, but the mechanism here — export controls applied to software — is a blunt tool. It also sets a precedent. If regulators can suspend access once, they can do it again, and companies and their customers have no guaranteed timeline for getting it back.
