US Government Orders Suspension of Anthropic's Fable 5 and Mythos 5 Models

On June 12, 2026, the US government issued an export control directive mandating Anthropic to suspend access to its AI models, Fable 5 and Mythos 5, for all foreign nationals due to national security concerns. This directive affects all users globally, including Anthropic's own foreign-national employees. The government cited potential methods of 'jailbreaking' the models, which could allow unauthorized access to sensitive information. Anthropic disputes the severity of these claims, arguing that the capabilities demonstrated are already available in other models. The suspension follows the models' public release on June 9, 2026, and has led to significant disruptions for users who were granted early access. Anthropic is working to comply with the directive while expressing concerns about the lack of transparency in the government's actions.

Key Points: • US government ordered Anthropic to suspend Fable 5 and Mythos 5 for foreign nationals. • The directive was issued due to alleged security vulnerabilities related to jailbreaking. • Anthropic disputes the claims, stating the capabilities are available in other AI models.
