Full Legal Analysis

AB 412 requires developers of generative artificial intelligence models to document any copyrighted materials they know were used in training their models. Developers must provide a mechanism on their websites for rights owners to request information about the use of their materials. Upon receiving a request, developers have 30 days to assess and respond with a list of covered materials likely present in their datasets, especially when a fingerprint is provided by the rights owner. Non-compliance results in daily violations, allowing rights owners to pursue civil action against developers. The bill exempts models trained exclusively using data the developer makes publicly available at no cost, as specified. Key definitions and terms are established to clarify the scope of the bill and its applicability to developers operating in California.
