The proposed bill seeks to regulate high-risk artificial intelligence (AI) systems in Washington State by introducing a new chapter to Title 19 RCW. It defines essential terms such as "algorithmic discrimination," "high-risk artificial intelligence system," and "deployer." The legislation requires developers and deployers to take reasonable care to protect consumers from algorithmic discrimination, mandating that developers provide comprehensive documentation on their AI systems and deployers implement risk management policies and conduct impact assessments prior to using these systems for significant decisions. Specific provisions are included for high-risk generative AI systems, ensuring that synthetic content outputs are identifiable to consumers.

Additionally, the bill outlines the requirements for impact assessments, which must cover the system's purpose, potential risks, data processing categories, and performance metrics, and mandates that deployers inform consumers about their interactions with AI systems. It also establishes exemptions for compliance with existing laws and internal research, while providing a civil action remedy for consumers against violations. The act emphasizes consumer rights and transparency in AI deployment, with a broad interpretation of protections and a narrow interpretation of exemptions, set to take effect on January 1, 2027.
