California SB 1047 — Safe and Secure Innovation for Frontier AI Models Act (VETOED)
CA · Cal. SB 1047 (2023-24 Reg. Sess.) — vetoed Sept. 29, 2024
California SB 1047 would have required safety testing, kill-switches, and developer liability for frontier AI models trained above compute/cost thresholds. Governor Newsom vetoed it on September 29, 2024 — a landmark veto that reshaped the U.S. frontier-AI policy debate.
Technical detail
SB 1047 (Wiener) — would have imposed safety-testing, shutdown-capability, third-party-audit, and incident-reporting duties on developers of 'covered models' (≥$100M training cost or ≥10^26 FLOPS), with whistleblower protections and AG enforcement. Vetoed Sept. 29, 2024; veto message cited risk that the bill would burden smaller models without targeting genuine frontier risks.
Who is protected: Public at large — would have addressed catastrophic-risk scenarios from frontier AI models
Who must comply: Developers of covered AI models (would have)
