THE U.S. Commerce Department has ordered Anthropic to suspend access to its AI models, Fable 5 and Mythos 5, for all foreign nationals, including its own employees. This directive, which Anthropic claims lacks transparency and specific evidence, has led the company to disable the models for everyone to comply with U.S. export controls.
Anthropic argues that the government believes a narrow jailbreak technique showcased vulnerabilities but contends that this standard, if applied broadly, could halt all new AI model deployments. The decision affects international partners such as NATO who utilized the models for cybersecurity purposes.
Anthropic emphasizes that other models, including OpenAI's GPT-5.5, offer similar capabilities without restrictions, and this situation sets a concerning precedent in how vulnerabilities in AI models could invoke export controls.
