California AB 2013 is a California artificial intelligence statute enacted in 2024 that requires developers of generative AI systems or services made available to Californians to publish specified documentation about training data.[1]
Background
[edit]California enacted a group of artificial intelligence laws in 2024 addressing generative AI transparency, digital replicas, election deepfakes, health care AI communications, privacy, and statutory AI definitions. California AB 2013 is part of that broader state-law package and addresses generative AI training data transparency.
