“The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance,” Anthropic said in a statement Friday evening.

The Commerce Department instructed Anthropic to suspend access to Fable 5 and Mythos 5 for any foreign national, which Anthropic said requires disabling the models entirely.

The company said it received the export control directive on Friday from the government.
