Claude Fable | Why Anthropic Disabled Its Most Powerful AI Model Days After Launch: Explained

Just days after launching Claude Fable 5 and Claude Mythos 5, Anthropic has suspended access to its most powerful AI models following a US government directive citing national security concerns. The order required access to be revoked for foreign nationals, but Anthropic disabled the models for all users to ensure compliance. The company has disputed the government's concerns over a potential AI "jailbreak", arguing that similar capabilities already exist in competing models and are routinely used for cybersecurity purposes. Anthropic says it is working to restore access and has called the directive a misunderstanding, warning that similar restrictions could impact future AI deployments across the industry.
