In brief<\/h4>\n
    \n
  • The U.S. government ordered Anthropic to suspend access to its two most advanced AI models, Fable 5 and Mythos 5, citing a national security concern over a potential jailbreak vulnerability.<\/li>\n
  • Anthropic complied but disputed the finding, arguing the vulnerability is simple and already replicable using other publicly available models like GPT-5.5.<\/li>\n
  • The company warned the directive sets a dangerous precedent that, if applied industry-wide, could halt all new frontier AI model deployments.<\/li>\n<\/ul>\n<\/div>\n

    The U.S. government issued an emergency export control directive on Friday <\/span>ordering Anthropic<\/span><\/a> to immediately suspend access to its two most powerful artificial intelligence models\u2014Claude Fable 5 and Claude Mythos 5, both <\/span>released just days earlier<\/span><\/a>\u2014for all foreign nationals, including the company’s own employees, citing national security concerns.<\/span><\/p>\n

    The directive bars any foreign national from accessing the models, whether inside or outside the United States. The sweeping scope of the order forced Anthropic to disable the models for its entire customer base to ensure compliance.<\/span><\/p>\n

    The letter did not provide specific details of its national security concern, but the government believes it has become aware of a method of bypassing, or “jailbreaking,” the publicly available Fable 5 model. Mythos 5, which has fewer guardrails and is particularly powerful at discovering cybersecurity exploits, was only available to select partners.<\/span><\/p>\n

    Anthropic disputed the severity of the finding. The company said it reviewed a demonstration of the technique and concluded that the vulnerabilities identified appear relatively simple, and that other publicly available models are able to discover them as well without requiring any bypass.<\/span><\/p>\n
