Full Legal Analysis

Senate Bill No. 942, known as the California AI Transparency Act, adds Chapter 25 to Division 8 of the Business and Professions Code, focusing on consumer protection through AI transparency. Effective January 1, 2026, the Act requires 'covered providers'—entities with generative AI systems exceeding 1 million monthly users—to provide a free AI detection tool. This tool must allow users to assess AI-generated content and output system provenance data without revealing personal provenance data. Additionally, covered providers must offer manifest disclosures for AI-generated content, ensuring they are clear and permanent where feasible. Latent disclosures must also be included, detailing the provider's name, AI system version, and content creation details, detectable by the AI tool. If a third-party licensee alters the AI system to omit required disclosures, the provider must revoke the license within 96 hours. Non-compliance results in a $5,000 civil penalty per violation, enforceable by the Attorney General or local authorities. The Act excludes non-user-generated entertainment content.
