# California AI Transparency Act (SB 942) takes effect August 2, imposing strict compliance requirements

> California's SB 942, the state's AI Transparency Act, went live on August 2 and it puts real teeth behind the idea that people deserve to know when media is machine made. Any generative AI provider with more than a million monthly users in the state now has to embed C2PA-compatible provenance signals into the images, video, and audio it produces, so downstream tools can trace where a file came from. The law goes further than quiet metadata. Vendors must offer a free, public detection tool that lets anyone check whether a piece of media was AI generated, and they must give users the option to attach a visible 'AI-generated' label. Noncompliance carries a penalty of 5,000 dollars per day per violation, which adds up fast at platform scale. What makes this notable is that California is once again setting a de facto national standard. Companies rarely build a separate pipeline just for one state, so provenance and detection features shipped to satisfy Sacramento tend to reach everyone. It is a concrete test of whether provenance standards can survive contact with production systems.
