Meta CEO Mark Zuckerberg was the chief architect of the “morally binding” AI accords that emerged from Tuesday’s White House lunch with President Donald Trump, Speaker and more than a dozen tech executives, according to five people familiar with the private meeting.

Zuckerberg, with the help of Nvidia CEO Jensen Huang, pitched the so-called AI accords to senior White House officials and some of the biggest names in tech during the luncheon, three of the people said. Both Huang as well as Trump administration officials helped shape the pact ahead of the meeting, according to two of the people.

All five people were granted anonymity because they were not authorized to share details of the discussions.

As part of the voluntary agreement, signatories would commit to the importance of enacting safeguards to mitigate potential risks from advanced AI models, but without a clear enforcement mechanism, it is unclear what if any consequences they may face for failing to do so.
