California governor vetoes major AI safety bill

California Governor Gavin Newsom vetoed the Safe and Secure Innovation for Frontier Artificial Intelligence Models Act (SB 1047) today. In his veto message, Governor Newsom cited multiple factors in his decision, including the burden the bill would have placed on AI companies, California’s lead in the space, and a critique that the bill may be too broad.

“While well-intentioned, SB 1047 does not take into account whether an AI system is deployed in high-risk environments, involves critical decision-making or the use of sensitive data. Instead, the bill applies stringent standards to even the most basic functions — so long as a large system deploys it. I do not believe this is the best approach to protecting the public from real threats posed by the technology.”

Newsom writes that the bill could “give the public a false sense of security about controlling this fast-moving technology.”

“Smaller, specialized models may emerge as equally or even more dangerous than the models targeted by SB 1047 – at the potential expense of curtailing the very innovation that fuels advancement in favor of the public good.”

The Governor says he agrees that there should be safety protocols and guardrails in place, as well as “clear and enforceable” consequences for bad actors. However, he states that he doesn’t believe the state should “settle for a solution that is not informed by an empirical trajectory analysis of Al systems and capabilities.”

Here is the full veto message:

In a post on X, Senator Scott Wiener, the bill’s main author, called the veto “a setback for everyone who believes in oversight of massive corporations that are making critical decisions” affecting public safety and welfare and “the future of the planet.”

“This veto leaves us with the troubling reality that companies aiming to create an extremely powerful technology face no binding restrictions from U.S. policymakers, particularly given Congress’s continuing paralysis around regulating the tech industry in any meaningful way.”

In late August, SB 1047 arrived on Gov. Newsom’s desk, poised to become the strictest legal framework around AI in the US, with a deadline to either sign or veto it as of September 30th.

It would have applied to covered AI companies doing business in California with a model that costs over $100 million to train or over $10 million to fine-tune, adding requirements that developers implement safeguards like a “kill switch” and lay out protocols for testing to reduce the chance of disastrous events like a cyberattack or a pandemic. The text also establishes protections for whistleblowers to report violations and enables the AG to sue for damages caused by safety incidents.

Changes since its introduction included removing proposals for a new regulatory agency and giving the state attorney general power to sue developers for potential incidents before they occur. Most companies covered by the law pushed back against the legislation, though some muted their criticism after those amendments.

In a letter to bill author Senator Wiener, OpenAI chief strategy officer Jason Kwon said SB 1047 would slow progress and that the federal government should handle AI regulation instead. Meanwhile, Anthropic CEO Dario Amodei wrote to the governor after the bill was amended, listing his perceived pros and cons and saying, “…the new SB 1047 is substantially improved, to the point where we believe its benefits likely outweigh its costs.”

The Chamber of Progress, a coalition that represents Amazon, Meta, and Google, similarly warned the law would “hamstring innovation.”

Meta public affairs manager Jamie Radice emailed Meta’s statement on the veto to The Verge:

“We are pleased that Governor Newsom vetoed SB1047. This bill would have stifled AI innovation, hurt business growth and job creation, and broken the state’s long tradition of fostering open-source development. We support responsible AI regulations and remain committed to partnering with lawmakers to promote better approaches.”

The bill’s opponents have included former House Speaker Nancy Pelosi, San Francisco Mayor London Breed, and eight congressional Democrats from California. On the other side, vocal supporters have included Elon Musk, prominent Hollywood names like Mark Hamill, Alyssa Milano, Shonda Rhimes, and J.J. Abrams, and unions including SAG-AFTRA and SEIU.

The federal government is also looking into ways it could regulate AI. In May, the Senate proposed a $32 billion roadmap that goes over several areas lawmakers should look into, including the impact of AI on elections, national security, copyrighted content, and more.
