Learn More Late last month, California Governor Gavin Newsom signed a historic law focused on increasing transparency among the companies building the world’s most advanced AI models. The law, formally titled the Transparency in Frontier AI Act and more commonly known as SB-53, fills a void Congress has left open.
Many AI policy bills have emerged at the state level, but only a few are designed to address potentially catastrophic risks from advanced AI systems. SB-53 is the first to make it into law. The law introduces protections for whistleblowers inside AI labs, mandatory reporting of certain safety incidents, and requirements that large developers publish so-called frontier AI frameworks to explain how they plan to mitigate catastrophic risks.
As the home of many of the world’s largest and most important AI companies, California has a unique role in AI policy. It is one of two jurisdictions with the greatest capacity to enact legally binding policies that affect frontier AI developers. The other, of course, is the U.S. federal government. But Washington, so far, has largely declined to act. That gives California huge influence over national, and even global, AI policy. SB-53 could provide a blueprint for other states and governments to follow—including, perhaps, a future Cong
