  "llmSummary": "California's SB 1047 required safety testing, shutdown capabilities, and third-party audits for AI models exceeding 10^26 FLOP or \\$100M training cost; it passed the legislature (Assembly 45-11, Senate 32-1) but was vetoed September 29, 2024, with Governor Newsom citing concerns about size-based rather than risk-based regulation. The bill's legislative success demonstrated political feasibility of frontier AI regulation while its veto revealed formidable industry opposition (from OpenAI, Anthropic, Google, Meta) and preference for federal approaches.",
