Summary

Official abstract published by the California legislature· summary

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.
