AB 2713: California AI Transparency Act: system provenance data.

Official summary

Legislative Counsel’s Digest (official, as of the latest version). Written by nonpartisan legislative staff; reproduced verbatim.

Existing law, the California AI Transparency Act, requires, among other things, a person that creates, codes, or otherwise produces a generative artificial intelligence (AI) system that has over 1,000,000 monthly visitors or users and is publicly accessible within the geographic boundaries of the state to make available an AI detection tool at no cost to the user. Existing law requires the AI detection tool to, among other things, allow a user to assess whether the image, video, or audio content was created or altered by that person’s generative AI system. Existing law defines terms for these purposes and makes these provisions generally operative on August 2, 2026.

Existing law also requires a large online platform to comply with specific duties relating to artificial intelligence, including, among other duties, allowing a user to inspect all available system provenance data that is compliant with widely adopted specifications adopted by an established standards-setting body by specified means. Existing law prohibits a large online platform from knowingly stripping any system provenance data or digital signature that is compliant with widely adopted specifications adopted by an established standards-setting body from content uploaded or distributed on the large online platform. Existing law makes these provisions, relating to a large online platform, operative on January 1, 2027.

This bill would revise the duties and prohibitions applicable to a large online platform relating to artificial intelligence, including the requirement for allowing a user to inspect system provenance data. The bill would specify that these provisions do not require a large online platform to take any action with respect to provenance data, system provenance data, or digital signatures that are not compliant with widely adopted specifications issued by an established standards-setting body.
