Anthropic has had a frenetic two-week stretch. On Tuesday of the previous week, the U.S.-based artificial intelligence firm unveiled its newest offering, Fable 5, which it characterized as bearing similarities to the widely discussed Claude Mythos Preview — yet equipped with safeguards intended to render it safe for broad use.
Yet by Friday, however, the company announced it had received a letter from the Department of Commerce instructing it to “suspend all access” to both Fable 5 and its newly updated Mythos model “by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees.” Unable to reliably sort its users by nationality to guarantee that only Americans could use the model, Anthropic pulled the plug on both models for everyone.
