The US government has issued a directive to suspend access to Fable 5 and Mythos 5, citing national security concerns due to a potential jailbreak method. Anthropic, the company behind the models, has complied with the directive but disagrees with the decision, stating that the finding of a narrow potential jailbreak should not be cause for recalling a commercial model. The company believes the government's action does not adhere to principles of transparency, fairness, and technical facts. The suspension affects all users, including foreign nationals, and Anthropic is working to restore access as soon as possible.
