Here is the paraphrased version of the content:

President Donald Trump signed an executive order on Tuesday aimed at giving the government an opportunity to evaluate powerful artificial intelligence models before they hit the market. Under the order, certain AI companies are asked—though not required—to submit their new models to the government for testing or assessment 30 days prior to public release. An earlier version of the directive had called for a voluntary review up to 90 days in advance, but industry insiders had pushed for a timeline closer to two weeks.

Trump had originally been scheduled to sign the stricter version of the order in late May, but delayed it following pushback from the industry, including from venture capitalist and former White House AI czar David Sacks. At the time, the president stated he did not want to take any action that might hinder U.S. AI companies in their competition with China. “Nothing in this section shall be construed to authorize the creation of a mandatory governmental licensing, preclearance, or permitting requirement for the development, publication, release, or distribution of new AI models, including frontier models,” the order, released Tuesday, states.

Trump had initially planned to sign the executive order with several top Silicon Valley CEOs in attendance, but ultimately signed the current version in private. Beyond the voluntary government review of AI models, the order also directs the Department of Justice to treat crimes such as AI-assisted hacking and unauthorized access as high-priority enforcement areas. This is not the president’s first executive order on AI. Last December, Trump signed an order directing the creation of a “one rulebook,” or a national AI policy framework, intended to preempt state-level AI regulations.
