The U.S. Commerce Department issued an order on June 12, 2026, requiring Anthropic to restrict access to its most advanced artificial intelligence models, specifically Claude Fable 5 and Mythos 5, from all foreign nationals. This action led to the immediate disabling of these models, rendering them inaccessible to all users.

This move has raised questions about the government’s intentions, with some suggesting that the restrictions might be aimed at keeping these advanced technologies within the U.S. for strategic purposes. The directive from the Commerce Department could be seen as a measure to control the distribution and use of cutting-edge AI models.

Anthropic complied with the government order promptly, highlighting the impact of regulatory decisions on the operation and availability of AI technologies. The decision is part of a broader landscape of growing concerns regarding the use and sharing of artificial intelligence models across national boundaries.

The consequences of such restrictions may influence both the business operations of companies like Anthropic and the global development of AI technologies. As advanced AI models play a significant role in various applications, their access and use are increasingly becoming critical issues in international policy and technology discussions.
