California Gov. Gavin Newsom has vetoed a landmark bill aimed at establishing first-in-the-nation safety measures for large artificial intelligence models.

California Gov. Gavin Newsom on Sunday vetoed a landmark artificial intelligence bill that was designed to have first-in-the-nation safety regulations against AI misuse. The big picture: The backers of the bill that would've required AI developers to comply with certain rules before developing models had argued it would provide AI safety with workable provisions at a time when Congress has stalled on the matter and the EU has taken a lead

The bill would have set a defacto national standard for AI safety testing and launched an intense lobbying campaign by the tech industry against it.
