# Anthropic is endorsing SB 53

# Claim

Anthropic is endorsing SB 53 , the California bill that governs powerful AI systems built by frontier AI developers like Anthropic. We’ve long advocated for thoughtful AI regulation and our support for this bill comes after careful consideration of the lessons learned from California's previous attempt at AI regulation ( SB 1047 ). While we believe that.

# Oracle Verdict
