Starting August 2, 2026, every AI-generated image, video, and audio clip produced by major providers operating in California will need to carry a hidden digital birth certificate. The California AI Transparency Act, originally passed as SB 942 and later amended by AB 853, requires large generative AI providers to embed provenance metadata into the content their systems create.
The law applies to generative AI providers with more than one million monthly users in California. Covered providers must include both “manifest” and “latent” disclosures in their AI-generated output. Manifest disclosures are the visible kind. Latent disclosures are the hidden metadata baked into the file itself, carrying details like the provider’s name and a creation timestamp.
Beyond embedding these fingerprints, providers are also required to build and offer free public detection tools. These tools must accept file uploads, URLs, and API calls.
The penalty structure carries a fine of $5,000 each, and every single day of noncompliance counts as a separate violation. The California Attorney General and local authorities both have enforcement power.
A phased rollout with expanding reach
