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 key terms such as "algorithmic discrimination," "high-risk artificial intelligence system," and "deployer." Developers of these systems are required to exercise reasonable care to protect consumers from algorithmic discrimination and must provide detailed documentation on the intended uses, limitations, and performance evaluations of their AI systems. Additionally, developers must update disclosures following any significant modifications to their systems. The bill also outlines the responsibilities of deployers, mandating them to implement risk management policies and conduct impact assessments before deploying AI systems for consequential decisions.

Moreover, the bill requires comprehensive impact assessments that include disclosures about the system's purpose, potential risks, data processing details, performance metrics, and transparency measures. Deployers must inform consumers when they interact with an AI system, explaining its function and the nature of consequential decisions. A three-year record retention requirement for all impact assessments is established, along with provisions for protecting trade secrets and confidential information. The bill allows for civil action remedies for consumers against developers or deployers for violations, with defenses for those who promptly rectify issues. The act is set to take effect on January 1, 2027, aiming to enhance accountability and transparency in the use of high-risk AI technologies.
