U.S. Eases Anthropic 'Mythos 5' Restrictions Only for Domestic Companies

The U.S. government has eased restrictions on Anthropic's top-tier artificial intelligence (AI) model, 'Mythos 5', limiting its use to specific companies and institutions within the country. This measure comes about two weeks after the Trump Administration announced export controls on Anthropic's AI models.

According to major foreign media outlets such as Reuters and the Washington Post on June 27, the U.S. Department of Commerce notified Anthropic in a letter dated June 26 (local time) that it would allow the use of Mythos 5 only for certain partners that have verified security measures in place. It is known that the approved entities will include around 100 companies and institutions within the United States. In a statement, Anthropic said that U.S. organizations operating critical national infrastructure can now redeploy the model.

As a result, South Korean companies such as Samsung Electronics, SK hynix, and SK Telecom, which previously secured early access to the predecessor model 'Mythos' through participation in the global AI security collaboration project 'Project Glasswing', remain restricted from using Mythos 5. The U.S. government continues to control access to cutting-edge AI services, affecting other companies such as OpenAI as well. On this day, OpenAI announced the release of its next-generation model, 'GPT-5.6', stating that initial access would be provided only to select institutions designated by the U.S. government. Industry observers have pointed out that the U.S. government's regulatory measures could impact the country's leadership in the AI industry.

Meanwhile, Anthropic and the U.S. government are reportedly discussing ways to restore access to 'Fable 5', a model with safety features designed for general users. Previously, on June 12, the Trump Administration had completely blocked access to Mythos 5 and Fable 5 for foreign nationals for national security reasons. However, with this latest measure, foreign employees of approved U.S. companies are now permitted to use the models.
