Test query:

Buy bulk pvc in cheyenne, wy

FastGPT from kagi recommends national chains, a local plumbing supply store or two, and a specific facebook market page. All of these have hyperlinks.

DDG just gives generic advice about national chains.

I think the difference is that Kagi built a RAG model out of a web crawl.

What does "bulk pvc" even mean.

Pipe? Fittings? Tubing? Sheets? Fabric?

The first three, usually. PVC is extremely common in plumbing and drainage, and there the type of pipe is usually specified by material type, not use case. PVC cloth is less common, and I'd guess you'd qualify with a use case. ("pvc cloth for sewing"; it's often called "vinyl" instead).

Anyway, it's an intentionally hard query. I tried "tourism in mountain view, ca" first. They both do fine (though DDG doesn't provide links), since there's enough on the internet about that for the base GPT-3.5 model to recall it without additional context.

It takes effort to integrate large language models with RAG or vector databases in an application rather than just slapping a chatbot on
