OpenAI urges California to strengthen AI safety bill it once opposed

OpenAI is calling on California to strengthen SB 53, a state AI safety law requiring frontier-model transparency and safety disclosures. OpenAI had previously opposed the bill before it passed.

Why it matters: OpenAI's reversal signals a broader industry recalibration toward state-level AI regulation as federal rulemaking stalls, and it raises the bar other labs may face as California's law becomes a de facto national standard. It also puts pressure on rivals to state clearly where they stand on binding safety disclosure requirements.
