AB 412: Generative artificial intelligence: training data: copyrighted materials.
What AB 412 does, verified August 15, 2026
This bill requires developers of generative artificial intelligence models to document any copyrighted materials used to train their models. The bill also mandates that developers make available a mechanism on their websites to allow rights owners to submit requests for information about the materials used to train the model. If a request is made, the developer must assess whether the requested material is likely to be present in their dataset and provide a list of materials that match the request within 30 days. Failure to comply can result in discrete violations, and rights owners can bring civil actions against the developer for specified relief. The bill excludes models that are trained exclusively using publicly available data at no cost.

CALIFORNIA LEGISLATURE— 2025–2026 REGULAR SESSION
Assembly Bill
No. 412
| Introduced by Assembly Member Bauer-Kahan (Coauthor: Assembly Member Kalra) |
February 04, 2025 |
An act to add Title 15.3 (commencing with Section 3115) to Part 4 of Division 3 of the Civil Code, relating to artificial intelligence.
LEGISLATIVE COUNSEL'S DIGEST
AB 412, as amended, Bauer-Kahan. Generative artificial intelligence: training data: copyrighted materials.
Existing federal law, through copyright, provides authors of original works of authorship, as defined, with certain rights and protections. Existing federal law generally gives the owner of the copyright the right to reproduce the work in copies or phonorecords and the right to distribute copies or phonorecords of the work to the public. Existing federal law provides that sound recordings fixed before February 15, 1972, are not subject to copyright, copyright but are subject to similar rights and protections under the Classics Protection and Access Act.
Existing law requires, before each time that a generative artificial intelligence system or service, as defined, or a substantial modification to a generative artificial intelligence system or service, released on or after January 1, 2022, is made available to Californians for use, regardless of whether the terms of that use include compensation, a developer of the system or service to post on the developer’s internet website documentation, as specified, regarding the data used to train the generative artificial intelligence system or service.
This bill would require a developer of a generative artificial intelligence model to make available on its internet website a mechanism allowing a rights owner to request information about the developer’s use of the rights owner’s covered materials that would allow the rights owner to provide the developer with, among other things, registration, preregistration, or index numbers for one or more covered materials. The bill would require a developer to document and retain any requests received from rights owners for a specified time period. The bill would, subject to specified exceptions, require a developer to, within 30 days of receiving that request from the rights owner, assess whether the developer used the rights owner’s covered materials to develop the model and provide the rights owner with a list of covered materials, as specified. The bill would provide that each day following the 30-day period that a developer fails to provide a rights owner with that information constitutes a discrete violation. The bill would authorize a rights owner who complies with specified requirements for submitting a request that is not provided with information according to these provisions to bring bring, subject to a certain notice and cure opportunity, a civil action against the developer for specified relief. The bill would provide that its requirements do not apply to a model that meets certain criteria, including, among other things, being trained exclusively using data the developer makes publicly available at no cost to users. The bill would provide that it does not impose liability on a telecommunications service, information service, or cable service provider, as specified. The bill would define various terms for these purposes.
The people of the State of California do enact as follows:
SECTION 1.
Title 15.3 (commencing with Section 3115) is added to Part 4 of Division 3 of the Civil Code, to read:TITLE 15.3. Copyrighted Materials Used for Artificial Intelligence Training
3115.
For the purposes of this(a) “Artificial intelligence” or “AI” means an engineered or machine-based system that varies in its level of autonomy and that can, for explicit or implicit objectives, infer from the input it receives how to generate outputs that can influence physical or virtual environments.
(b) (1) “Covered material” means either of the following:
(A) A material registered, preregistered, or indexed with the United States Copyright Office pursuant to the federal Copyright Act of 1976, Public Law 94-553 (17 U.S.C. Sec. 101 et seq.).
(B) A sound recording fixed before February 15, 1972, enforceable under the Classics Protection and Access Act, Title II of Public Law 115-264 (17 U.S.C. Secs. 301(c) and 1401).
(2) “Covered material” does not mean a material that is in the public domain.
(c) “Rights owner” means the owner of a covered material.
(d) “Developer” means a business, person, partnership, corporation, or other entity that designs, codes, produces, or substantially modifies a GenAI model and that does either of the following:
(1) Uses the GenAI model commercially in California.
(2) Makes the GenAI model available to Californians for reasonably foreseeable commercial use.
(e) “Generative artificial intelligence” or “GenAI” means an artificial intelligence system that can generate derived synthetic content, including text, images, video, and audio, that emulates the structure and characteristics of the system’s training data.
3115.5.
(a) A developer shall make available on its internet website a mechanism allowing a rights owner to request information about the developer’s use of the rights owner’s covered materials. The mechanism shall allow a rights owner to provide the developer with all of the following:(1) Documentation sufficient to establish the rights owner’s identity.
(2) The physical or electronic signature of the rights owner or a third party authorized to act on their the rights owner’s behalf.
(3) Registration, preregistration, or index numbers for one or more of the rights owner’s covered materials.
