# Sharing our compliance framework for California's Transparency in Frontier AI Act

# Claim

On January 1, California's Transparency in Frontier AI Act ( SB 53 ) will go into effect. It establishes the nation’s first frontier AI safety and transparency requirements for catastrophic risks. While we have long advocated for a federal framework, Anthropic endorsed SB 53 because we believe frontier AI developers like ourselves should be transparent.

# Relevance

Appendix III, section two: vendor threshold and platform capability evidence

# Oracle Verdict

This is a low-signal vendor radar item. Keep it as context only unless a later benchmark, deployment, procurement change, or labour-market datapoint turns it into direct Appendix III evidence.
