Governor Newsom signs SB 53, advancing California’s world-leading artificial intelligence industry - Governor Gavin Newsom

Governor Newsom today signed into law Senate Bill 53, the Transparency in Frontier Artificial Intelligence Act (TFAIA), authored by Senator Scott Wiener (D-San Francisco) – legislation carefully designed to enhance online safety by installing commonsense guardrails on the development of frontier artificial intelligence models, helping build public trust while also continuing to spur innovation in these new technologies. The new law builds on recommendations from California’s first-in-the-nation report, called for by Governor Newsom and published earlier this year — and helps advance California’s position as a national leader in responsible and ethical AI, the world’s fourth-largest economy, the birthplace of new technology, and the top pipeline for tech talent.
