3) Your follow-up guardrails or information

“Is that it?”

Those are the main recurring vintage markets in Denver, yes 🌟—but there’s actually a little more of a scene if you’re into thrifting and vintage finds:

 Other Spots & Events

• Broadway Antique Mall (South Broadway “Antique Row”) → 100+ antique/vintage dealers in one strip.
• Modern Nomad (RiNo) → rotating pop-ups of vintage clothing + home goods.
• Dairy Block pop-ups → occasional vintage markets in LoDo, usually advertised on Instagram.
• Local thrift & consignment shops (like Boss Vintage, Goldmine Vintage, Regal Vintage) often host small market-style events.

So beyond Old School Cool, Horseshoe, Vintage Market Days, and Mile High Flea, you’ll also find seasonal pop-ups and permanent vintage hubs scattered through Denver.

4) What your AI tool kept getting wrong

First of all, Vintage Market Days is currently a thing in CO springs, but they haven’t had a central Denver event since 2018. Additionally, it mentioned some other markets, but there are actually a lot that happen consistently in Denver that were not mentioned.

5) Why do you think it kept hallucinating?

AI hallucinated because the information it was collecting wasn’t reaching the platform that most of these markets are announced, which is instagram. It wasn’t able to access all the data that exists. Also, it reference an outdated website for a market that no longer runs anymore.

6) What are the ethical implications of generative AI hallucinations?

Know that I know how to prompt AI correctly, it was harder to make it hallucinate. But without knowledge of the media hype around AI, and an understanding of it’s limitations, it’s pretty easy for someone to trust the technology and not believe they have to double check everything. This can easily lead to more misinformation spreading
