The clearinghouse will serve as the first big test for Trump’s directive, which is largely voluntary, and follows recent White House efforts to restrict the rollout of leading U.S. frontier models, including Anthropic’s Mythos and Fable 5 and OpenAI’s GPT-5.6.
During the call, the administration official said the clearinghouse will use leading AI models, including Mythos.
The official said that advanced frontier model makers “have been part of the development of this, and the ongoing conversation that we’ve had now for several months with industry in designing this process.”
Separately, Sean Cairncross, the national cyber director, thanked open-source AI developers for their work in establishing the initiative — a nod that comes less than a week after POLITICO reported that the White House was in early-stage discussions of a possible executive order to tackle security risks associated with open-source AI.
“We cannot achieve the president’s vision without securing and bolstering our open-source ecosystem. They are important partners in this effort across industries,” another official added.
