Frontier AI governance statutory and regulator sources
This archive packet preserves California's enacted SB 53 text and the European Commission's current GPAI Code of Practice page. It distinguishes California statutory duties from the EU code's voluntary compliance pathway and does not determine whether OpenAI or any other developer is covered, compliant, or independently effective.
Official enacted California bill text; coverage and duties remain jurisdiction- and definition-specific.
