Beginning February 1, 2027, the Washington attorney general can sue to enforce this law. The AG can act for the state or on behalf of residents. Any violation counts as an unfair or deceptive act under the Consumer Protection Act. Only the AG may bring Consumer Protection Act cases to enforce this chapter.
Beginning February 1, 2027, any government agency must tell you when you are interacting with an AI system. The notice must be clear, in plain language, and shown before or at the time of the interaction. It cannot use tricks or dark patterns to hide the notice. A link to a web page is allowed. The notice is required even if it seems obvious.
Beginning February 1, 2027, large AI providers must add provenance data to images, video, or audio they create or materially change. The label lets users see if the content was created or changed by their AI. They must do this when it is commercially and technically reasonable, and make the label hard to remove using common standards like C2PA. Providers do not include information about identified people. Minor edits like brightness changes, resizing, or noise removal do not count as material changes.
Beginning February 1, 2027, these AI disclosure rules do not apply to some products and uses. They do not cover business-to-business uses, sales, licensing, or distribution of generative AI. They also do not cover products, services, websites, or apps that provide only video games or other interactive experiences, including virtual storefront browsing and buying. Systems used only for upscaling, noise reduction, or compression are also exempt.
Beginning February 1, 2027, the law does not force companies to reveal trade secrets or confidential, proprietary details about AI design or use. This protects business secrets but limits how much technical detail the public can see about how a system works.
