Approved by the governor and chaptered as Chapter 138, Statutes of 2025.

What the law does

California enacted transparency and safety requirements for large developers of frontier AI models. The law concerns model developers, so its effect on robotics depends on how those models are developed and used.

This is broader AI policy rather than a robotics-specific statute. The official text defines which developers and models it covers.
