AB 2013 was chaptered on 28 September 2024 as Chapter 817 of the Statutes of 2024. Developers of generative AI systems made available to Californians, including systems released since 1 January 2022, must post documentation on their websites by 1 January 2026 with a high-level summary of the datasets used to train them, covering sources, the number of data points, whether copyrighted or licensed data is included and when the data was collected.

Why it matters

Developers offering generative AI in California had to disclose what their models were trained on from 2026, information that copyright claimants and buyers can use.
