California now has two distinct transparency regimes for generative artificial intelligence. Assembly Bill 2013 requires public documentation about training data, while Senate Bill 942—the California AI Transparency Act—addresses the provenance of AI-generated images, video, and audio. The laws overlap in subject matter, but their coverage, disclosures, and implementation dates are different.
AB 2013 has applied since January 1, 2026. SB 942, as amended by AB 853, became operative on August 2, 2026. Developers should analyze each law independently and document why a particular product, release, or business role is covered or excluded.
