The US government just cut off the rest of the world from Anthropic’s most powerful AI systems. On June 12, the Commerce Department issued an export-control directive that immediately suspended foreign access to Anthropic’s Fable 5 and Mythos 5 models, which had launched just three days earlier on June 9.

How we got here

The roots trace back to February 27, when a presidential directive led to the Pentagon designating Anthropic as a “supply-chain risk.” The reason: Anthropic refused the Pentagon’s demands for unrestricted use of its technology, particularly for applications like autonomous weapons systems and domestic surveillance.

Following that designation, federal agencies were directed to stop using Anthropic’s models entirely. The export-control order in June represents the next logical escalation, a tool typically reserved for semiconductors and defense technology now being wielded against AI model weights.

Anthropic CEO Dario Amodei has actually been one of the loudest voices in favor of strong export controls on advanced AI. He’s publicly advocated for careful regulation of advanced chips and model weights. The irony is that the government is now using those same export-control mechanisms against his own company, not because of what Anthropic did with its technology, but because of what it refused to do.
