Original title: Transparency in Frontier Artificial Intelligence Act

SB 53

Summary

The law, signed by Governor Newsom, sets transparency and safety requirements for frontier AI developers. Large frontier developers must publish a framework on their website describing how they incorporate national and international standards and industry best practices. It creates a mechanism to report critical safety incidents, protects whistleblowers, sets a civil penalty enforceable by the Attorney General, and establishes CalCompute, a consortium within the Government Operations Agency to develop a public computing cluster framework.

Who it applies to

It also covers whistleblowers disclosing health and safety risks posed by frontier models, and involves state bodies such as the Office of Emergency Services and the California Department of Technology.
