Trump Administration’s National Security Hammer Forces Anthropic to Shut Down Advanced AI Models Worldwide Over Foreign Access Risks

Anthropic has abruptly disabled its most advanced AI models, Fable 5 and Mythos 5, for all users around the world after the US government issued an order requiring the suspension of access for foreign nationals due to national security concerns. The directive focused on a narrow jailbreak vulnerability related to software flaw detection, prompting the company to comply by taking the models offline entirely rather than risk partial enforcement. This move highlights the Trump administration’s strong commitment to protecting American technological superiority and preventing sensitive AI capabilities from falling into the wrong hands.

While Anthropic publicly disagreed with the order, describing the risk as minor and comparable to other publicly available models, the company followed legal requirements and is working to restore access where possible. AWS also revoked global access in coordination with the directive, marking a significant escalation in how frontier AI systems are treated as controlled technology similar to advanced weapons or encryption tools. This decisive action underscores the importance of robust export controls in an era where AI development can directly impact national defense and economic security.

The episode serves as a clear reminder of why America must maintain leadership in artificial intelligence while implementing smart safeguards against adversaries. Under the Trump administration’s America First approach, prioritizing national security ensures that groundbreaking innovations benefit American citizens and allies rather than empowering potential rivals. As the AI race intensifies, such firm policies protect the United States from emerging threats while encouraging responsible development in this critical field.
