US orders suspension of access to Fable 5 and Mythos 5

Anthropic said the US government has directed the company to suspend access to Fable 5 and Mythos 5 for all users, citing national security concerns and export control authorities. The company said it received the directive on June 12 and was not given detailed technical findings in the letter. According to Anthropic, the government believes it has identified a way to bypass or “jailbreak” the models. Anthropic said it reviewed the material and считает the reported capability is similar to issues seen in other publicly available models, and does not amount to a broad jailbreak of the systems. The company said it is complying with the order and removing access while disagreeing with the decision. Anthropic also said access to its other models will remain available, and that it hopes to restore Fable 5 and Mythos 5 access after further review.
