The proposed bill establishes comprehensive regulations for the development, deployment, and use of high-risk artificial intelligence (AI) systems in Washington State. It introduces key definitions, including "algorithmic discrimination," "high-risk artificial intelligence system," and "consequential decision." Developers are required to take reasonable care to protect consumers from algorithmic discrimination and must provide detailed documentation on the intended uses, limitations, and risk management measures of their systems. Additionally, outputs from generative AI systems must be identifiable and accessible to consumers. Deployers are mandated to implement a risk management policy aligned with recognized standards to mitigate foreseeable risks when making consequential decisions.

The bill also requires deployers to conduct an impact assessment before the initial deployment and significant updates of high-risk AI systems, detailing the system's purpose, potential risks, data processing, performance metrics, and transparency measures. It includes provisions for civil actions against developers and deployers, establishing a rebuttable presumption of reasonable care for those who comply with the outlined requirements. Exemptions are provided for compliance with existing laws, cooperation with law enforcement, and internal research. The act aims to enhance accountability and transparency in AI technologies while protecting consumer rights, with provisions taking effect on January 1, 2027.
