Address each statutory element in the dataset summary — sources or owners, how the data furthers the system's purpose, number and types of data points, copyright/trademark/patent or public-domain status, purchased-or-licensed status, presence of personal information or aggregate consumer information, any cleaning or modification, first-use dates, collection time period, and any use of synthetic data generation.
Deadline: By January 1, 2026
transparency→ developerCal. Civ. Code § 3110
Refresh and re-post the public training-data summary before each subsequent public release or substantial modification of a covered generative AI system, so the disclosure stays current rather than ending at the initial January 1, 2026 deadline.
Deadline: Before each release
