On June 12-13, 2026, the U.S. government issued an export control directive ordering Anthropic to suspend all foreign access to its latest AI models, Fable 5 and Mythos 5, citing national security concerns (CNBC). Anthropic complied by abruptly disabling both models for all customers, not just foreign ones, to ensure immediate compliance (Anthropic official statement). The models had only launched days earlier and were touted as state-of-the-art across multiple benchmarks, with Fable 5 being Anthropic's first publicly available frontier model with advanced safeguards (CNBC). The Commerce Department's decision reportedly followed a company's claim of a jailbreak against Mythos that could bypass safety classifiers (Axios). Anthropic disputed the severity, stating it had only seen evidence of a narrow jailbreak finding minor vulnerabilities, and that other models like GPT-5.5 have similar capabilities (Ars Technica). The company called the order a "misunderstanding" and is working to restore access (Reuters). This event comes on top of Anthropic's prior clash with the Department of Defense, which declared it a supply chain risk earlier this year (CNBC). The forced removal of flagship models damages Anthropic's competitive position, especially as both Anthropic and OpenAI have confidentially filed for IPOs (CNBC). The move may also disrupt existing compute deals, such as the reported $1.25B/month agreement with SpaceX (CNBC). In summary, the government action represents a severe regulatory setback, effectively sidelining Anthropic's most advanced products and raising uncertainty around its IPO timeline and customer commitments.
