Deadline: by_2026-01-01
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_2026-01-01
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.
