The Trump administration issued a federal export-control order that forced AI startup Anthropic to block access to its newest models [1, 2].
This move signals a tightening of federal oversight on artificial intelligence, potentially setting a precedent for how the U.S. government restricts the global distribution of advanced computing technology. It also highlights the tension between national security interests and the open nature of AI development.
The federal directive required Anthropic to first block foreign nationals from accessing the Fable 5 and Mythos 5 models [1, 2]. This restriction eventually expanded to include all users, effectively pulling both models from public access [1, 2].
White House officials said the order was necessary due to export-control concerns [1, 2]. The directive was issued in mid-April 2024, and the models were shut down that Friday [1, 2].
AI policy advocates said the move reflects an ad-hoc regulatory approach [1, 2]. These critics said that such unpredictable government interventions could stifle innovation within the domestic tech sector [1, 2].
Anthropic has not provided further public details regarding the specific technical capabilities of Fable 5 and Mythos 5 that triggered the federal order [1, 2]. The company complied with the White House directive to ensure alignment with U.S. law [1, 2].
“The Trump administration issued a federal export-control order that forced AI startup Anthropic to block access to its newest models.”
The removal of these models suggests that the U.S. government is prioritizing the prevention of technological leakage to foreign adversaries over the commercial availability of AI tools. By using export controls rather than a formal legislative framework, the administration is exercising broad executive power to manage AI risks, which may create uncertainty for other AI developers regarding the stability of their product launches.
