Just three days after its release, Anthropic's 'most capable AI model available to the public,' Claude Fable 5, was ordered shut down by the U.S. government, along with Claude Mythos 5, according to TechCrunch. This swift federal intervention came despite Anthropic's stated focus on AI safety, raising questions about innovation versus national security. The immediate restriction affects even those working within the United States.

Anthropic champions AI safety and responsible development. Yet, its most advanced models are now subject to immediate government shutdown due to national security concerns. This tension underscores AI's increasing strategic value.

This swift, decisive action signals future frontier AI development will face increasing government scrutiny and export controls, potentially fragmenting the global AI landscape.

The Commerce Department's Unprecedented Directive

The Commerce Department directed Anthropic to limit access to Claude Fable 5 and Claude Mythos 5 to US nationals only, Forbes reported. This clarified initial reports of a complete shutdown, specifying a nationality-based restriction. Anthropic is complying, suspending foreign nationals from both models. This immediate adherence sets a precedent for how AI developers respond to government mandates.

The Commerce Department's directive reclassifies advanced AI as a strategic, export-controlled technology. It shifts AI from a commercial product to a geopolitical asset, reflecting a governmental view of AI as critical infrastructure requiring national security oversight.

Export Controls Target Foreign Nationals

The US government issued an export control directive to Anthropic, suspending foreign nationals' access to Fable 5 and Mythos 5, Al Jazeera reported. This extends traditional export controls, typically for physical goods, to digital AI models. The ban affects foreign nationals even within the US, including those working at Anthropic itself. This broad application impacts external access, internal operations, and the global talent pool in US-based AI companies.
