Version:

The California AI Transparency Act requires a person that creates, codes, or otherwise produces a generative artificial intelligence 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 that, among other things, allows a user to assess whether image, video, or audio content, or content that is a combination thereof, was created or altered by that persons generative artificial intelligence system and outputs any system provenance data that is detected in the content. Existing law makes the California AI Transparency Act operative on January 1, 2026.

This bill would delay the operation of the California AI Transparency Act until August 2, 2026.

This bill would, beginning January 1, 2027, additionally require a large online platform, as defined, to, among other things related to the provenance of content on the platform, detect whether any provenance data that is compliant with widely adopted specifications adopted by an established standards-setting body is embedded into or attached to content distributed on the large online platform. The bill would also require, beginning January 1, 2028, a capture device manufacturer, with respect to any capture device the capture device manufacturer first produced for sale in the state on or after January 1, 2028, to, among other things, provide a user with the option to include a latent disclosure in content captured by the capture device that conveys certain information, including the name of the capture device manufacturer. The bill would define capture device to mean a device that can record photographs, audio, or video content, including, but not limited to, video and still photography cameras, mobile phones with built-in cameras or microphones, and voice recorders.

Existing law requires a covered provider to include a latent disclosure in AI-generated image, video, or audio content, or content that is any combination thereof, created by the covered providers GenAI system that, among other things, conveys certain information and is permanent or extraordinarily difficult to remove, to the extent it is technically feasible.

This bill would, beginning January 1, 2027, prohibit a GenAI system hosting platform, as defined, from knowingly making available a GenAI system that does not place disclosures, pursuant to those provisions.

This bill would declare that its provisions are severable.
