- Requires covered generative AI providers (persons that create, code or otherwise produce a generative AI system publicly accessible in California) to make available a free AI-content detection tool and to include disclosures in AI-generated content. The 1,000,000 monthly user threshold in the original text was deleted from the covered provider definition by SB 1000 (Chapter 861, Statutes of 2026, urgency statute), per the CalMatters digest; bill text not seen.
- obligations
- Covered providers must: make available a free AI detection tool allowing users to assess whether image, video, or audio content was created by the provider's generative AI system; include manifest disclosures in AI-generated content; support latent disclosures (content provenance metadata). AB 853 (2025) added requirements for large online platforms and GenAI hosting platforms effective January 1, 2027.

- notes
- Signed September 19, 2024. Original operative date January 1, 2026, extended to August 2, 2026 by AB 853 (signed October 13, 2025), which amended Business and Professions Code Section 22757.6 to state 'This chapter shall become operative on August 2, 2026.' Confirmed against the AB 853 bill text on leginfo.legislature.ca.gov. AB 853's separate large-online-platform and GenAI-hosting-platform requirements remain on a January 1, 2027 timeline. AMENDMENTS (2026-10-10): the Governor's September 30, 2026 AI signing release lists SB 1000 (Becker, California AI Transparency Act) and AB 2713 (Wicks, California AI Transparency Act: system provenance data) as signed. The CalMatters Digital Democracy digest for SB 1000 (re-read this round) says it would delete the user threshold from the definition of covered provider, replace the term AI detection tool with disclosure verification tool, and take effect immediately as an urgency statute (Chapter 861, Statutes of 2026); it also reportedly requires disclosure of whether the GenAI system created or altered the content, delays operation for assistive-technology systems, and adds a civil action against providers falsely claiming assistive-technology status. AB 2713 (Chapter 856, Statutes of 2026) reportedly provides that large online platforms need not act on provenance data or digital signatures that do not meet widely adopted specifications of an established standards-setting body; this AB 2713 detail is aggregator-only. The obligations field predates these amendments and still uses the term AI detection tool. Bill text was not seen (leginfo returned 403).
