Umm… nothing was really “explained”, here.

It’s just a larger rehash of what’s already been mentioned: U.S. Govt blocked access to Fable/Mythos to U.S. Citizens only. Anthropic didn’t have the ability to do this, so they locked it out.

Dean Ball, a former White House official who contributed to the AI Action Plan the administration issued in the summer of 2025, said in a post on X that the order suggests all “non-Americans” would be restricted from using ⁠Anthropic’s latest ​models, including those based in the U.S.

“This means you should expect to have to prove your citizenship to use Anthropic ​models,” Ball said.

There is the real reason, folks.

Yet another effort to force mandatory ID checking to access a website.
