Bill Summary

CONCERNING MEASURES EFFECTIVE NO LATER THAN JUNE 30, 2026, TO INCREASE TRANSPARENCY FOR ALGORITHMIC SYSTEMS.

AI Summary

This bill aims to increase transparency and accountability for artificial intelligence (AI) systems in Colorado by establishing new requirements for developers and deployers of high-risk AI systems. The bill, which will take effect on June 30, 2026, requires developers to use reasonable care to protect consumers from potential algorithmic discrimination, including making documentation and impact assessments available to deployers. Developers must also disclose known risks of algorithmic discrimination to the attorney general and deployers within 90 days of discovery. Similarly, deployers must implement a risk management policy and program to identify and mitigate potential discriminatory risks, complete annual impact assessments, and provide clear disclosures about their AI systems. The bill mandates that consumers be informed when they are interacting with an AI system and requires detailed reporting and documentation to help prevent unintended discriminatory outcomes. Notably, the bill provides a rebuttable presumption of compliance if developers and deployers follow the specified guidelines and any additional rules adopted by the attorney general, with protections for proprietary information and trade secrets. The overall goal is to create more transparent, accountable, and fair AI systems that minimize the risk of discriminatory practices across various applications.
