Aug. 4, 2026 — One of the nation’s first AI transparency laws officially took effect on Monday. It’s the first of dozens of state AI laws that will start to be enforced over the coming months and years.

California’s AI Transparency Act now requires the largest generative AI developers—such as OpenAI, Anthropic, Google, and Microsoft—to provide users with an AI detection tool. AI-generated images, video, and audio have to carry a disclosure that may be both visible and machine-readable.

The Transparency Act, sponsored as SB 942 by California state Sen. Josh Becker and enacted in Sept. 2024, is open to enforcement starting this week. AI transparency advocates are watching closely to see how the largest tech companies comply with the new law.

What the transparency act requires: disclosure

The Transparency Act requires companies to embed provenance data within any image or video created or altered with that company’s GenAI tool. Consumers must be given an option to include a manifest disclosure that identifies content as AI-generated. It must be clear, conspicuous, and appropriate to the medium. Consumer’s aren’t required to post the disclosure under the new law.

The Transparency Act also requires a covered provider—again, this applies to only the largest AI systems with at least one million monthly visitors—to include a latent disclosure in AI-generated image, video, audio content, or content that is any combination of the three. This latent disclosure, embedded in the content, can be accessed to convey the provenance of the content.

The Act also affects the relationship between a large AI developer and a third-party licensee. Any AI developer covered under the Act, if they are aware that a third-party licensee using their GenAI system without complying with the disclosures required by the Act, must demand the third-party licensee come into compliance or revoke the license. That demand must come within 96 hours (four days) of discovery of noncompliance.

software already available for compliance

Yesterday, Sen. Becker was joined at a media event by Burhan Yanbolu, founder and CEO of Hardin AI, a company that specializes in providing the software tools needed to comply with AI disclosure laws such as SB 942 and New York State’s new AI-disclosure-in-advertising law.

TBN Certify, a Hardin AI product, “scans content, detects AI-generated material, and issues a cryptographically signed compliance certificate anyone can independently verify,” Yanbolu wrote in a social media post.

David Evan Harris, the California-based AI expert and driving force behind the AI Transparency Act, also appeared with Sen. Becker yesterday. He spoke about the power of the “California effect”: Policies enacted in California have a larger-than-life impact. “By dint of their pioneering policymaking” in a state with 40 million consumers, Harris wrote recently, California legislators “often set standards for the world.”
