## Quick Reference

The Colorado AI Act (SB24-205) is the first comprehensive state AI law in the US. It requires developers and deployers of "high-risk" AI systems to use reasonable care to avoid algorithmic discrimination, and mandates disclosure when AI interacts with consumers.

**Q: Do I need to tell Colorado consumers they're interacting with an AI?**
**A:** Yes. Any AI system intended to interact with consumers must disclose this, unless it's obvious to a reasonable person [§ 6-1-1704].

**Key rule (§ 6-1-1704):** AI systems must disclose to each consumer that they are interacting with an AI system.

**Rule:** Developers and deployers of high-risk AI must use reasonable care to protect consumers from algorithmic discrimination.

**Applies to:** Developers and deployers of high-risk AI systems doing business in Colorado

**Effective date:** June 30, 2026

**Key rules:**
- Developers must document and disclose AI system risks [§ 6-1-1702]
- Deployers must implement risk management programs [§ 6-1-1703]
- Must disclose to consumers when AI is making consequential decisions [§ 6-1-1703(4)]
- Must disclose when any AI interacts with consumers [§ 6-1-1704]
- Notify AG within 90 days of discovering algorithmic discrimination [§ 6-1-1702(5)]
