The Trump administration is pressing Meta to submit its artificial intelligence models for voluntary review, which would allow the government to evaluate the A.I.’s abilities and vulnerabilities, four people familiar with the confidential request said.

The request, which was made in emails with Meta, is the latest example of the administration’s efforts to step up oversight of the A.I. industry after promoting a hands-off approach to the powerful technology. Less than two weeks ago, the government ordered Anthropic to remove access to its newest model, citing national security concerns.

Meta is the only major U.S. developer of A.I. technology that has not reached an agreement to voluntarily share its models with the federal government for review, said the people familiar with the request, who spoke on the condition of anonymity because they were not authorized to discuss the matter publicly. OpenAI, Anthropic, Google, xAI and Microsoft have all agreed to submit their models to the government’s A.I. safety group, known as the Center for A.I. Standards and Innovation.

“We share the administration’s goal of advancing U.S. leadership on robust and secure frontier A.I.,” Francis Brennan, a Meta spokesman, said in a statement on Tuesday. “While we are working through the details, we hope to sign the agreement soon.”

Ben Kass, a Commerce Department spokesman, said the Center for A.I. Standards and Innovation, which is housed in the department, regularly engaged with companies about voluntary agreements.

“This story is not unusual,” he said. “It is the very work CAISI is supposed to be doing.”

The latest batch of A.I. models have increased concerns about cybersecurity, though some industry insiders say the fears are overblown, since the new technology can be used to defend computer networks as easily as it can be used to attack them.
