Executive summary: SB 53 is a proposed California bill that would require only the wealthiest and most advanced AI companies—currently just OpenAI and xAI—to adopt transparency and safety practices for frontier AI models, drawing on expert recommendations to improve oversight without burdening startups or the open-source community.
Key points:
Limited scope targeting frontier developers: SB 53 only applies to “large developers” that both train models exceeding 10²⁶ FLOPs and earn over $100 million annually—criteria met so far only by OpenAI and xAI—ensuring early-stage startups and smaller open-source projects remain unaffected.
Transparency-focused obligations: Covered companies must publish safety policies, model cards, and report critical safety incidents, but they retain discretion to redact sensitive security or proprietary information.
Influence of the California Report: SB 53 operationalizes principles from the 2025 California Report on Frontier AI Policy, including public transparency, post-deployment incident monitoring, and whistleblower protections extended to contractors and advisors.
No expansion of liability or regulatory scope: The bill does not create a new agency, expand AI companies’ legal liability for harms, or permit private lawsuits over transparency failures—only the California Attorney General may enforce it via civil action.
Alignment with other state and international laws: SB 53 complements emerging AI legislation in New York and Michigan and in some respects goes further than the EU AI Act, especially in requiring public—not just regulator-facing—transparency.
Designed to avoid regulatory fragmentation: Because its obligations mirror those in other major jurisdictions and only affect billion-dollar companies, SB 53 is unlikely to contribute to a harmful regulatory patchwork or stifle innovation.
