Fable 5 and Mythos 5 suspended: Washington cites national security against Anthropic – La Nouvelle Tribune

US Commerce Secretary Howard Lutnick ordered Anthropic to suspend its AI models Fable 5 and Mythos 5, citing national security. A third-party firm allegedly found a bypass of Mythos 5's protections, but Anthropic vigorously disputes the claim. Unable to filter users by nationality, the company cut global access to the models. The suspension comes as Anthropic prepares for an IPO with a $965 billion valuation.
