California’s 2024 legislative session has been marked with exciting developments and a clear focus on setting the rules of the road for artificial intelligence (AI), with some measures becoming law and others stalling out along the way. Last month, Governor Newsom signed 17 bills regulating AI in the Golden State. Notably, Governor Newsom vetoed SB 1047, which would have imposed safety requirements on developers of large models to avoid certain harms. In vetoing the bill, Governor Newsom noted that it was not comprehensive or precise enough, improperly focused on large models even though small ones could present similar risks, and did not take into account whether an Al system is deployed in high-risk environments, involves critical decision-making, or uses sensitive data. Newsom’s veto also represents a big win for the numerous industry members, politicians, and academics who lobbied against the bill, arguing that its passage would stifle innovation in the space. Nevertheless, the AI bills Newsom did sign are expected to have wide-ranging impacts on the AI industry. A summary of those bills is below.
