Anthropic said it is disabling all customer access to its Fable 5 and Mythos 5 AI models to comply with a Trump administration directive.
“The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees,” the company said in a statement.
Anthropic added that to ensure compliance, “the net effect” of the order meant it had to “abruptly disable” access for all customers, including in the US. Other models will not be affected.
The directive, which Anthropic said it received at 5:21 pm Friday, marks the most significant action yet by the Trump administration to place restrictions on cutting-edge models.
That’s despite earlier statements, including in an executive order, that the US would not be imposing a licensing regime for model reviews. A US official confirmed the Commerce Department sent the letter.
