On Monday, Anthropic introduced an official endorsement of SB 53, a California invoice from state senator Scott Wiener that may impose first-in-the-nation transparency necessities on the world’s largest AI mannequin builders. Anthropic’s endorsement marks a uncommon and main win for SB 53, at a time when main tech teams just like the Shopper Expertise Affiliation (CTA) and Chamber for Progress are lobbying in opposition to the invoice.

“Whereas we imagine that frontier AI security is finest addressed on the federal degree as an alternative of a patchwork of state laws, highly effective AI developments received’t anticipate consensus in Washington,” stated Anthropic in a weblog submit. “The query isn’t whether or not we want AI governance — it’s whether or not we’ll develop it thoughtfully immediately or reactively tomorrow. SB 53 provides a stable path towards the previous.”

If handed, SB 53 would require frontier AI mannequin builders like OpenAI, Anthropic, Google, and xAI to develop security frameworks, in addition to launch public security and safety reviews earlier than deploying highly effective AI fashions. The invoice would additionally set up whistleblower protections to workers who come ahead with security considerations.

Senator Wiener’s invoice particularly focuses on limiting AI fashions from contributing to “catastrophic dangers,” which the invoice defines because the loss of life of a minimum of 50 individuals or greater than a billion {dollars} in damages. SB 53 focuses on the intense facet of AI danger — limiting AI fashions from getting used to offer expert-level help within the creation of organic weapons or being utilized in cyberattacks — relatively than extra near-term considerations like AI deepfakes or sycophancy.

California’s Senate accepted a previous model of SB 53 however nonetheless wants to carry a ultimate vote on the invoice earlier than it could actually advance to the governor’s desk. Governor Gavin Newsom has stayed silent on the invoice up to now, though he vetoed Senator Weiner’s final AI security invoice, SB 1047.

Payments regulating frontier AI mannequin builders have confronted important pushback from each Silicon Valley and the Trump administration, which each argue that such efforts might restrict America’s innovation within the race in opposition to China. Buyers like Andreessen Horowitz and Y Combinator led among the pushback in opposition to SB 1047, and in latest months, the Trump administration has repeatedly threatened to dam states from passing AI regulation altogether.

One of the widespread arguments in opposition to AI security payments are that states ought to go away the matter as much as federal governments. Andreessen Horowitz’s head of AI coverage, Matt Perault, and chief authorized officer, Jai Ramaswamy, printed a weblog submit final week arguing that a lot of immediately’s state AI payments danger violating the Structure’s Commerce Clause — which limits state governments from passing legal guidelines that transcend their borders and impair interstate commerce.

Nevertheless, Anthropic co-founder Jack Clark argues in a submit on X that the tech trade will construct highly effective AI methods within the coming years and might’t anticipate the federal authorities to behave.

“We’ve got lengthy stated we would favor a federal commonplace,” stated Clark. “However within the absence of that this creates a stable blueprint for AI governance that can not be ignored.”

OpenAI’s chief world affairs officer, Chris Lehane, despatched a letter to Governor Newsom in August arguing that he mustn’t go any AI regulation that may push startups out of California — though the letter didn’t point out SB 53 by identify.

OpenAI’s former head of coverage analysis, Miles Brundage, stated in a submit on X that Lehane’s letter was “crammed with deceptive rubbish about SB 53 and AI coverage typically.” Notably, SB 53 goals to solely regulate the world’s largest AI firms — notably ones that generated a gross income of greater than $500 million.

Regardless of the criticism, coverage specialists say SB 53 is a extra modest strategy than earlier AI security payments. Dean Ball, a senior fellow on the Basis for American Innovation and former White Home AI coverage adviser, stated in an August weblog submit that he believes SB 53 has a very good probability now of turning into regulation. Ball, who criticized SB 1047, stated SB 53’s drafters have “proven respect for technical actuality,” in addition to a “measure of legislative restraint.”

Senator Wiener beforehand stated that SB 53 was closely influenced by an skilled coverage panel Governor Newsom convened — co-led by main Stanford researcher and co-founder of World Labs, Fei-Fei Li — to advise California on how you can regulate AI.

Most AI labs have already got some model of the inner security coverage that SB 53 requires. OpenAI, Google DeepMind, and Anthropic frequently publish security reviews for his or her fashions. Nevertheless, these firms will not be sure by anybody however themselves, so generally they fall behind their self-imposed security commitments. SB 53 goals to set these necessities as state regulation, with monetary repercussions if an AI lab fails to conform.

Earlier in September, California lawmakers amended SB 53 to take away a bit of the invoice that may have required AI mannequin builders to be audited by third events. Tech firms have beforehand fought some of these third-party audits in different AI coverage battles, arguing that they’re overly burdensome.
