Signal California bill requires disclosure of training data composition

Summary

This signal highlights California's transparency-focused approach to regulating AI. Its Assembly Bill 2023 obliges AI providers to disclose information about their training data, including whether it included personal information or copyrighted works. A separate AI Transparency Act requires some generative AI providers to watermark what their systems produce and to offer free tools so the public can check whether a file was created or altered with those systems. The report contrasts this with the European Union, which focuses on defining banned uses and assigning liability. Together they show that jurisdictions are pursuing different goals through AI regulation, which could make compliance more complex for companies operating across regions.
