Anthropic Suspends AI Tools for Foreign Nationals Amid US Security Concerns

AI developer Anthropic has suspended access to its advanced Fable 5 and Mythos 5 models for all global users following a directive from the United States government. The Trump administration issued an export control order, citing national security concerns, which specifically mandated the company to block access for all foreign nationals, including those within the U.S. and its own foreign employees.

Although the government did not provide explicit details about the national security risks, Anthropic understands the order is likely related to a potential "jailbreak" method. This method reportedly could bypass Fable 5's built-in safety mechanisms, potentially allowing the identification of software vulnerabilities.

Anthropic has expressed that it believes this situation is a "misunderstanding" and is actively working to restore access to its models while adhering to the government's directive. The company also conveyed its disagreement with the decision, arguing that a limited potential security bypass should not necessitate the withdrawal of a widely used commercial AI model. This action represents a notable intensification of U.S. efforts to regulate advanced AI technologies, which are increasingly seen as critical national security assets.
