US halts Anthropic AI models amid foreign national worries

Anthropic has taken its latest AI models, Fable 5 and Mythos 5, offline following a U.S. government directive aimed at preventing their use by foreign nationals. This move is part of new export controls marking a significant step in restricting access to advanced AI technology due to national security concerns. Anthropic disagrees with the government's directive, arguing that it lacked transparency and did not clarify the associated risks.

The directive coincides with an executive order by President Trump that establishes a framework for voluntary national security vetting of advanced AI systems prior to their release.
