The government used a private "is informed" letter to apply deemed export controls, which regulate a foreign national's access to technology *within* the US. This powerful tool effectively halted the Fable model's use, even by Anthropic's own foreign national employees, without public rule-making or debate.

Dario Amodei, CEO of Anthropic, frames the debate over selling advanced GPUs to China not as a trade issue, but as a severe national security risk. He compares it to selling nuclear weapons, arguing that it arms a geopolitical competitor with the foundational technology for advanced AI, which he calls "a country of geniuses in a data center."

Contrasting government actions—forcing Anthropic to block foreign access while simultaneously defending xAI's data centers for military operations—reveal a coherent strategy. Frontier AI is no longer just a commercial product; it's being treated as a strategic national asset subject to direct government control and intervention.

The US government is restricting Anthropic's commercial rollout of its new model, Mythos, over concerns it could hamper the government's own access to compute. This move treats AI capacity as a strategic national resource and effectively creates a de facto licensing system for powerful models, marking a new era of AI governance.

The U.S. government is repurposing export control laws, traditionally for physical goods, to halt Anthropic's AI model release. By restricting access for foreign national employees, the administration created a "de facto ban" that sets a new, aggressive precedent for regulating AI development and deployment.

Contrary to expectations, US government actions like the DoD's "supply chain risk" label and export controls on Anthropic's models have boosted its business adoption. This scrutiny inadvertently acts as a powerful marketing tool, signaling the model's immense power and lending credibility to Anthropic's safety-focused brand.

The government's sudden order for Anthropic to disable its Fable 5 model demonstrates that access to crucial AI tools can be revoked instantly due to national security concerns, creating significant operational risk for dependent companies.

U.S. AI strategy is incoherent. While the Treasury Department tightly controls domestic access to advanced models like Anthropic's Mythos for national security, the administration also facilitates Nvidia's sale of the very AI chips to China that will accelerate their ability to develop competing models.

The Department of War is threatening to blacklist Anthropic for prohibiting military use of its AI, a severe penalty typically reserved for foreign adversaries like Huawei. This conflict represents a proxy war over who dictates the terms of AI use: the technology creators or the government.
