Last verified May 2, 2026
Summary
California Senate Bill 53, the Transparency in Frontier Artificial Intelligence Act, was signed by Governor Newsom on September 29, 2025 after the prior frontier-AI bill (SB 1047) was vetoed in 2024. The Act is codified at California Business and Professions Code Chapter 25.1 (Sections 22757.10 through 22757.16) per Stats. 2025, Ch. 138, with all sections taking effect January 1, 2026. SB 53 imposes obligations on "large frontier developers" — developers of frontier AI models meeting compute and revenue thresholds defined in the statute.
Key requirements: (1) publication of a written frontier AI safety framework describing how the developer assesses and mitigates catastrophic risk; (2) transparency reports prior to deploying new frontier models; (3) reporting of critical safety incidents to the California Office of Emergency Services within specified timeframes; (4) whistleblower protections for employees who report violations of the Act or substantial dangers; (5) creation of a public-benefit AI compute cluster ("CalCompute") — separate provision.
Enforcement by the California Attorney General. Per § 22757.15(a), a large frontier developer that fails to publish or transmit a compliant document, makes a statement in violation of § 22757.12(e), fails to report an incident as required by § 22757.13, or fails to comply with its own frontier AI framework is subject to a civil penalty in an amount dependent upon the severity of the violation that does not exceed one million dollars ($1,000,000) per violation.
