The US banned Anthropic’s Fable 5 release, but the numbers don’t seem to care

The US government forced Anthropic to withdraw its new models, Fable 5 and Mythos 5, due to national security concerns. This decision followed Amazon researchers discovering a way to bypass security barriers in the Fable 5 model. Cybersecurity researchers expressed alarm over this action, signing an open letter warning of the risks, noting similar vulnerabilities exist in other models. Anthropic confirmed that these vulnerabilities are not unique to Fable 5. This development reflects the growing tension between AI innovation and national security requirements, raising questions about future regulations for this technology.
