How does Trump’s White House AI accord work?

U.S. President Donald Trump met with AI industry leaders at the White House to sign a voluntary pact called the White House Accord on Super Intelligence. The agreement, signed by Meta, Nvidia, Google, OpenAI, xAI, and Anthropic, requires companies to implement internal controls to monitor security risks, with four layers of oversight. It is non-binding and does not impose penalties, but leaves open the possibility of making these measures mandatory later.
