Colorado's AI law watered down, drops explanation mandate for companies

Two years of intense debate in Colorado over AI regulation ended quietly early Tuesday when the legislature passed a compromise measure, SB 189, that significantly weakens the state's first-in-the-nation law governing the technology. Originally passed in 2024 as SB 205, the law had never taken effect due to concerns from the tech industry and a failed special session. Governor Jared Polis formed a working group that produced the new framework. SB 189 passed the House 57-6 and the Senate 34-1 with broad bipartisan support, and now awaits the governor's signature.

Instead of requiring companies, governments, and other groups to disclose how their AI systems help make decisions on hiring, loans, and housing, SB 189 only mandates that consumers be notified when AI is used for such consequential decisions and be given an opportunity to appeal. The law's start date is pushed back from June 2026 to January 2027. Reactions are mixed: proponents like the Colorado Technology Association call it "a more balanced path forward," while consumer advocates say it's a good first step but still lacks transparency. Critics note that even developers often don't understand how their AI works.
