Does California's AI Transparency Act apply to my AI image generator?

Yes, if your generator has more than 1,000,000 monthly users and is publicly accessible in California. Since 2 August 2026 every AI image, video and audio output needs a latent disclosure, users must be offered a visible one, and you must run a free public detection tool with an API.

What you need

  • A latent disclosure with your name and the system
  • A visible disclosure users can choose
  • A public detection tool for your outputs

The law

These bind you.

A latent disclosure in every image, video and audio output

In force since 2 August 2026

If your generative system has over 1,000,000 monthly users and is publicly accessible in California, embed a latent disclosure in every AI-generated image, video and audio file: where feasible, your name, the system's name and version, the time and date, and a unique identifier. It must be detectable by your own detection tool, follow widely accepted industry standards, and be extraordinarily difficult to remove. Text is not covered.

“This chapter shall become operative on August 2, 2026.”
