Anthropic Halts Foreign Access to Advanced AI Models Fable 5 and Mythos 5 Following US Government Directive

AI developer Anthropic has suspended access to its Fable 5 and Mythos 5 artificial intelligence models for all foreign nationals, complying with a directive from the U.S. government citing national security concerns. The company stated it received the export control order on Friday, June 13, without specific details of the national security threat, but understands it relates to a method of bypassing or 'jailbreaking' Fable 5's safeguards. Anthropic expressed disagreement with the government's handling of the matter, calling it a 'misunderstanding' and hoping to restore access.
