Generative Artificial Intelligence: Training Data Transparency (AB 2013)

In forceLawBinding

Requires developers of generative AI systems made available to Californians (released or substantially modified since 1 Jan 2022) to post documentation on their websites about training data, including dataset sources, data types, whether copyrighted or personal information is included, and collection periods. Narrow exemptions cover security, aircraft and federal defence systems.

Why it matters

Every public-facing generative AI provider must maintain a public training-data summary; a federal court refused to block the law in March 2026.
