After realising the power of frontier AI models, the US administration has shifted away from an initial hands-off posture, says this academic.

Anthropic's Fable AI was shut down following a U.S. government directive limiting access to U.S. nationals, exposing growing tensions between AI safety and regulation.

The Commerce Department instructed Anthropic to suspend access to Fable 5 and Mythos 5 for any foreign national, which Anthropic said requires disabling the models entirely.
