AB 2013 added Sections 3110 and 3111 to the California Civil Code. It applies to a person, partnership, corporation, or state or local government agency that designs, codes, produces, or substantially modifies an AI system or service for use by members of the public. Training includes testing, validation, and fine-tuning. For an in-scope generative AI system or service made publicly available to Californians, the developer must publish a high-level summary of the training datasets. The documentation must address dataset sources or owners, how the datasets support the system's intended purpose, dataset scale and data-point types, intellectual-property or public-domain status, whether data was purchased or licensed, inclusion of personal or aggregate consumer information, cleaning or other processing, collection periods, first-use dates, and the use of synthetic data. The disclosure duty does not apply to systems whose sole purpose is security and integrity, systems whose sole purpose is operating aircraft in the national airspace, or national-security, military, or defense systems made available only to a federal entity. AB 1170, Chapter 67 of the Statutes of 2025, made a code-maintenance correction to Section 3111 effective January 1, 2026. It did not alter the substance of the disclosure obligation. The enacted title identifies no dedicated enforcing authority, express enforcement procedure, or standalone civil penalty.
Regulation
Verified record
- Risk classification summary
- Opacity concerning generative-AI training data and associated intellectual-property, personal-data, dataset-provenance, and synthetic-data risks. The statute is transparency-focused and does not assign systems to a statutory high-risk tier.
- Requirements summary
- Publish training-data documentation on the developer’s website by January 1, 2026, and before each later public release or substantial modification. Disclose dataset sources or owners, purpose relationship, approximate scale, data types, intellectual-property status, purchase or licensing status, personal and aggregate consumer information, cleaning or processing, collection periods, first-use dates, and synthetic-data use.
- Affected entities
- Developers, including persons, partnerships, corporations, and California state or local agencies, that design, code, produce, or substantially modify generative AI systems or services released on or after January 1, 2022, for public use in California. Statutory sole-purpose security, aircraft-operation, and specified federal defense systems are exempt.
- Enforcement summary
- Civil Code Sections 3110-3111 name no dedicated enforcing authority and create no express enforcement process or private cause of action.
