US government restricts foreign access to advanced AI models

From physical hardware blockades to direct cloud software restrictions. The U.S. Department of Commerce's Bureau of Industry and Security (BIS) recently issued an emergency export control directive targeting AI startup Anthropic, legally banning all foreign nationals, both inside and outside the United States, from accessing its advanced Mythos 5 and Fable 5 frontier AI models.

🔹 **Emergency Software Directive**: Citing critical national security concerns, intelligence officials feared these models could be jailbroken to discover and exploit cybersecurity vulnerabilities in critical public infrastructure, prompting the first-ever direct restriction on active software models.

🔹 **Complete Model Shutdown**: Because Anthropic was unable to reliably verify the citizenship and nationality of its API users in real-time, the company ultimately decided to completely shut down and disable both the Mythos 5 and Fable 5 models for all users worldwide.

🔹 **Export Control Precedent**: This action marks a historic pivot in American policy. Rather than relying solely on blocking high-end semiconductor chips, the administration is now directly regulating software-based frontier AI, triggering significant anxiety among G7 allies about their long-term technological dependence on the United States.

🔹 **Broader Policy Context**: The directive follows closely on the heels of Executive Order 14409, which focused on promoting safe AI innovation. This subsequent, aggressive enforcement action signals that the administration intends to use unilateral state powers to police frontier models aggressively.
