Bottom line
- On Sept. 29, 2024, the Governor returned SB 1047 to the Senate without his signature.
- He says the bill set its threshold by model cost and size, and not by the risk of how a system is deployed.
Background

Key claims
- “I am returning Senate Bill 1047 without my signature.” (paragraph 1)
- “California is home to 32 of the world’s 50 leading AI companies” (paragraph 3)
- “By focusing only on the most expensive and large-scale models, SB 1047 establishes a regulatory framework that could give the public a false sense of security about controlling this fast-moving technology.” (page 2)
- “While well-intentioned, SB 1047 does not take into account whether an AI system is deployed in high-risk environments, involves critical decision-making or the use of sensitive data.” (page 2)
- “A California-only approach may well be warranted - especially absent federal action by Congress - but it must be based on empirical evidence and science.” (page 2)
