California's AI transparency law took effect this week, requiring makers of widely used AI generation tools to embed provenance data in the content their products create. The law's definition of "transparency," however, may not give consumers the information they need when they first encounter an image, video, or recording. The law, passed in 2024, requires AI companies to include two types of provenance data with generated content. The first is metadata attached to the content file that identifies who created the media, when, and with what tool. The second is a smaller set of the same information hidden within the content itself, such as within the pixels of a generated image. AI companies must also provide a free public detection tool that can identify either kind of provenance data. The law requires AI creation tools to offer users a way to attach a visible or audible label indicating the content was AI-generated, but it does not require the tools to affix such a label to everything they generate.

What platforms must do starting next year

The law's authors knew provenance data would be of limited use if consumers never saw it. Starting next year, content distribution networks such as social networks must at least alert users to the availability of the data. A platform can provide a link to the provenance data, allow users to download it, or offer a special interface for displaying it. The law does not specify that the interface must appear adjacent to the content. Some platforms might affix an "AI-generated" label directly to the content. Others might display a text link reading "content credentials available" or a small icon. The law's effectiveness could therefore depend on platform operators' design choices rather than on the technical provenance system the law establishes.

Two definitions of transparency

The law illustrates that the AI industry and its regulators are working with two different definitions of "transparency." One means that AI companies' tools establish and preserve the technical "story" of a piece of content. The other refers to an assurance to content consumers that images, videos, or audio recordings really are what they purport to be, and that they can be taken at face value.

Why this matters for legal professionals

For legal professionals, the law creates distinct compliance obligations for AI companies and the platforms that distribute their content. The statute leaves platforms room to choose how they surface provenance data, which means those design decisions will shape whether the law delivers meaningful transparency. AI for Legal teams advising clients in this space will need to track both the technical requirements and the consumer-facing obligations. AI for Government professionals can see in this statute how provenance data requirements are written into state law, and where the law leaves room for interpretation.
