In September 2024, Governor Gavin Newsom requested that Dr. Fei-Fei Li, Co-Director of the Stanford Institute for Human-Centered Artificial Intelligence; Dr. Mariano-Florentino Cuéllar, President of the Carnegie Endowment for International Peace; and Dr. Jennifer Tour Chayes, Dean of the UC Berkeley College of Computing, Data Science, and Society, prepare a report focused on artificial intelligence (AI) frontier models. In March 2025, a draft report was shared for feedback. The Working Group deeply appreciates the individuals and organizations from numerous disciplines and sectors who participated by sharing valuable insights, references, and suggestions, including, in some cases, by making their responses public to contribute to the broader discourse.
On June 17, 2025, the Joint California Policy Working Group on AI Frontier Models published the final report, California Report on Frontier AI Policy. This report leverages broad evidence—including empirical research, historical analysis, and modeling and simulations—to provide a framework for policymaking on the frontier of AI development. Building on this multidisciplinary approach, this report derives policy principles that can inform how California approaches the use, assessment, and governance of frontier AI—principles rooted in an ethos of “trust but verify.” This approach takes into account the importance of innovation while establishing appropriate strategies to reduce material risks.
This effort represents scholarly work from each of the Co-Leads and does not represent the positions of their institutions. The Co-Leads were aided in the production of this report by scholars from their institutions acting in their own, independent capacity. The draft report was reviewed by experts covering a range of disciplines. The Co-Leads solicited feedback, reflections, and additional information from a variety of disciplines and sectors for consideration in advance of the final report.
