SB 1000: California AI Transparency Act.
What SB 1000 does, verified October 2, 2026
The bill aims to regulate artificial intelligence (AI) transparency in California. It requires content providers to make available a disclosure verification tool at no cost to users, which must meet certain criteria. The bill also eliminates the requirement for providers to offer users the option to include a manifest disclosure in content created by their AI systems. Furthermore, providers must now include a latent disclosure stating whether the content is generated or modified by AI. The bill declares it will take effect immediately.

LEGISLATIVE COUNSEL'S DIGEST
SB 1000, Becker. California AI Transparency Act.
Existing law, the California AI Transparency Act (CATA), beginning August 2, 2026, generally regulates provenance data disclosure in content generated by artificial intelligence (AI), including by requiring a covered provider to make available an AI detection tool at no cost to the user that meets certain criteria. Existing law requires a covered provider to offer the user the option to include a certain manifest disclosure in image, video, or audio content, or content that is any combination thereof, created or altered by the covered provider’s generative artificial intelligence (GenAI) system and requires a covered provider to include a certain latent disclosure in AI-generated image, video, or audio content, or content that is any combination thereof, created by the covered provider’s GenAI system. Existing law defines “covered provider” for these purposes to mean a person that creates, codes, or otherwise produces a generative AI system that has over 1,000,000 monthly visitors or users and is publicly accessible within the geographic boundaries of the state.
This bill would recast those provisions to, among other changes, delete the user threshold from the definition of “covered provider,” replace the term “AI detection tool” with “disclosure verification tool,” delete the above-described requirement of a covered provider to offer the user the option to include a manifest disclosure in content, and additionally require a covered provider to include in the above-described latent disclosure whether the GenAI system created or altered the content. The bill would delay CATA’s operation with respect to a GenAI system that is designed to primarily function as assistive technology, as defined, would prohibit a covered provider from falsely representing that a GenAI system is designed to primarily function as assistive technology, and would punish a covered provider who makes such a false representation with a certain civil action, as specified.
This bill would declare that it is to take effect immediately as an urgency statute.
The people of the State of California do enact as follows:
SECTION 1.
The Legislature finds and declares all of the following:(a) Establishing an ecosystem of information online that allows consumers to verify the provenance of content, including, but not limited to, whether or not it was generated or modified by a generative artificial intelligence (AI) system is paramount to combating misinformation and disinformation as it relates to public health, election integrity, preventing fraud, extortion, or using generative AI to create content for other malicious purposes.
(b) Conveying conflicting manifest and latent provenance information to consumers is detrimental to trust in both the provenance of content and the authenticity of any person, entity, or institution conveyed in that content.
(c) AI provenance technology is still developing, and ensuring that information conveyed to consumers regarding a piece of content’s provenance is accurate, accessible, and resilient to common transformations to the extent technically feasible over time requires legislation to be adaptive and technologically agnostic.
(d) Accordingly, encouraging the adoption, interoperability, and continued development of widely accepted technical standards is necessary to promote reliable, scalable, and evolvable content provenance mechanisms.
SEC. 2.
Section 22757.1 of the Business and Professions Code is amended to read:22757.1.
