The U.S. Commerce Department issued a directive to Anthropic on June 12, 2026. This order mandated the company to block all foreign nationals from accessing its two most sophisticated large language models. In response, Anthropic quickly disabled its Claude Fable 5 and Mythos 5 models, rendering them inaccessible to all users.

The decision came as a significant move by the government, potentially shaping the landscape of artificial intelligence availability worldwide. By restricting access, the U.S. may be aiming to safeguard its technological assets. Protecting advanced AI models could also suggest an effort to maintain a competitive edge on the global stage.

The response to this order was immediate, as Anthropic took action within hours to comply. This rapid implementation highlights the seriousness with which the directive was followed. It underscores the importance attributed to these AI models.

This move has sparked discussions regarding the balance between national security and global technological collaboration. It raises questions about the future access of advanced AI systems and the implications it might have for international cooperation in technology.
