Law note · California
Generative Artificial Intelligence Training Data Transparency Act (AB 2013)
Signed September 28, 2024, this law requires developers of generative AI systems to publish on their websites summaries of training data used, disclosing copyright status, data ownership, and whether personal information or third-party copyrighted content (including news) was included; compliance required by January 1, 2026. The law does not grant publishers an explicit opt-out or compensation right but creates de facto disclosure pressure on AI developers who scraped news content for training.
A December 2025 federal executive order directed review of state AI regulations for conflict with federal policy, creating some enforceability uncertainty.
