The US government issued an export control directive ordering Anthropic to block access to its two most advanced AI models, Fable 5 and Mythos 5, for all foreign nationals, citing national security concerns. Because compliance would be impossible without disabling the models entirely, Anthropic suspended global access to both, just days after rolling out Fable 5 for free to millions of users. Anthropic disputes the justification, stating the government's evidence amounts to a narrow, already-known jailbreak, and argues that applying this standard industry-wide would effectively halt all new frontier model deployments.
