US President Donald Trump hosted a meeting of top technology bosses on Tuesday for what he called "an extraordinary gathering" of the minds that are "building America's Golden Age".
The guest list included leaders from OpenAI, Anthropic, Nvidia, SpaceX, Meta and Google - all key figures in the US AI industry.
The meeting came as some tech executives and experts have called for tighter oversight of AI, citing concerns about the potential risks it poses to humanity.
Here are three key takeaways from Trump's tech summit at the White House.
1. AI 'self-regulation' pact
Trump took questions from the media for around 30 minutes alongside top tech leaders after the closed-door meeting.
The president said the executives had signed a "morally binding" document that would serve as a "form of protection" from AI's potential risks.
Under the agreement, which Trump posted online, the companies are responsible for ensuring the safety of their own technology.
The firms also agreed to implement safeguards to keep models operating as intended and quickly detect and fix any issues.
They will also work with "independent auditors" to assess whether their AI systems are working as intended and ensure their platforms do not "hack or access technical systems in unintended ways."
The accord was signed by Trump, Google boss Sundar Pichai, Anthropic chief Dario Amodei, Meta's Mark Zuckerberg, OpenAI President Greg Brockman, SpaceX's Elon Musk and Nvidia chief executive Jensen Huang.
"It's almost like a constitution, in a way," Trump said.
"And the biggest people in the world signed that, and I signed it as president."
Trump added that he will set up a board to oversee the safety of AI tools. He did not specify who would be on that board.
Zuckerberg said the accord gives the "American people and customers the confidence that the technology works" as intended, calling the meeting a "historic conversation".
Amodei called it a way "to win safely", referring to the president's comment earlier this month that "whoever wins AI, wins".
But not all technology experts are impressed with the accord.
Nanyang Technological University AI governance researcher Jose Miguelito Enriquez said the pact shows "emerging consensus" but does not address whether AI developers should be held accountable for incidents.
It is "deeply unimpressive" and comes despite calls from some world leaders and industry figures for tighter regulations around the technology, said law professor Kimberlee Weatherall from the University of Sydney.
The agreement appears to allow firms to "define what counts as safety" and does not state what consequences there are for any breaches, Weatherall said.
"The accord should be ignored, for the distraction it is," she added.
