The California AI Transparency Act (CATA) requires covered generative artificial intelligence (GenAI) providers to provide tools for identifying AI-generated content and to embed specified provenance information in certain AI-generated images, videos, and audio content.
SB 1000 expands and revises CATA’s transparency requirements for any person that creates, codes, or otherwise produces a GenAI system for public use in California. Among other changes, SB 1000 removes the existing one-million-monthly-user threshold from the definition of a “covered provider;” requires providers to make a free disclosure verification tool available; and requires latent disclosures to identify whether content was created or altered by GenAI. SB 1000 also establishes requirements for providers that license GenAI systems to third parties while temporarily exempting qualifying assistive-technology systems until January 1, 2029.
The law took effect immediately as an urgency statute.
Employers that create, code, or otherwise produce their own GenAI system that is publicly accessible in California should review their disclosure, verification, provenance data, and third party licensing practices for compliance.
SB 1000 amends sections 22757.1, 22757.2, 22757.3, 22757.4, and 22757.5 of, and adds and repeals section 22757.4.1 of, the Business and Professions Code. It was chaptered as Chapter 861, Statutes of 2026, on September 30, 2026.
