[UPDATE] Trump, Speaker Johnson and six AI chiefs sign a voluntary four-layer safety accord with no enforcement

A separate order Trump signed tells federal agencies to stop saying "AI" and use "Super Intelligence" or "SI" instead.

After a White House lunch on Tuesday, Sept. 29, Trump and House Speaker Mike Johnson announced a safety accord signed by leaders of Anthropic, OpenAI, Google, Meta, Nvidia and Elon Musk's AI company. The pledge. Each company commits to four layers of checks: internal controls, an internal team that oversees them, an outside auditor, and an independent board committee. Nothing enforces any of it. The framing. Trump called the accord "morally binding" and said "it's almost like a constitution in a way." What next. Trump said he would name an AI czar within three or four days.
