California's Senate Bill 53, known as the Transparency in Frontier Artificial Intelligence Act (TFAIA), has passed the state legislature and now awaits Governor Gavin Newsom's signature, with observers indicating a high probability of enactment. The bill, which mandates safety and transparency requirements for large developers of powerful artificial intelligence models, has undergone significant amendments to incorporate industry feedback, according to Miles Brundage, who stated in a recent tweet, "Reference to SB 53 though to clear, I think there's a good chance this sails through without veto. It's been very amended to reflect a lot of industry input already and is literally based on the task force Newsom created."
The legislation requires large AI developers to implement and publish safety and security protocols detailing testing procedures for catastrophic risks. These companies must also release public transparency reports summarizing risk assessments and steps taken to mitigate potential dangers before deploying new models. Additionally, the bill includes provisions for reporting critical safety incidents to the state within 15 days and establishes robust whistleblower protections for employees disclosing information about catastrophic risks or violations of the TFAIA.
SB 53's journey follows the veto of a more expansive AI safety bill, SB 1047, by Governor Newsom last year, who subsequently formed the Joint California Policy Working Group on AI Frontier Models. This working group, comprising academics and industry experts, recommended a "trust but verify" approach to AI governance, which Senator Scott Wiener's SB 53 aims to implement through disclosure requirements. Major AI companies like Anthropic have publicly endorsed SB 53, noting that it formalizes practices they already follow and creates a level playing field for transparency.
The bill also establishes CalCompute, a public cloud computing cluster within the Government Operations Agency, designed to advance safe, ethical, and sustainable AI development by fostering research and innovation. This initiative aims to build state capacity for AI use, aligning with California's role as a global leader in AI innovation. While some industry groups have expressed concerns about potential burdens on innovation, the widespread amendments and alignment with the Governor's task force recommendations suggest a consensus-driven path toward responsible AI regulation.
