Anthropic on Friday announced it's disabled access to its Fable 5 and Mythos 5 artificial intelligence models to comply with an export control directive from the U.S. government that cited "national security authorities."

The company said it received an order at 5:21 p.m. ET, instructing it to suspend all access to the models "by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees."

Anthropic abruptly disabled the models for all of its customers in order to ensure compliance, but said all of its other models will not be affected.
