California executive order directs work on AI oversight, including a frontier-model kill switch
What changed?
The Governor issued an executive order asking a working group to recommend, within about two months, measures to strengthen California's AI safety and security laws, including whether developers of frontier models should maintain a shutdown capability and whether independent third parties should prepare safety plans. It creates no new obligations itself. Recorded from secondary reporting; confirm the order's number and text on the Governor's site.
What does it mean in practice?
No obligations yet; frontier-model developers should watch for the working group's recommendations.
