California enacts first-in-nation AI safety regulations

California Governor Gavin Newsom signed a new law establishing AI safety measures for large-scale models. The legislation aims to prevent catastrophic misuse of advanced AI technologies. The law requires companies to implement and disclose safety protocols for AI systems exceeding a "frontier" computing power threshold. It defines catastrophic risk as causing over $1 billion in damage or more than 50 injuries/deaths. This bill follows Newsom's previous veto of broader regulations and incorporates expert recommendations. It includes whistleblower protections and fines for violations, seeking to balance innovation with public safety.
