Idk I earnestly tried using LLMs to find me the smallest by volume regular ATX PC case 3 months ago and it was a nightmare. That info is out there, but it could not avoid mentioning ITX, mini atx (sometimes because Reddit posters messed up) and just missed a bunch of cases. And letting in any mistakes meant I had to double check every volume calculation it did.

I found the Jonsbo D41 without the help of LLM despite trying. (There might be a few smaller but they are 3x the price)

LLMs don’t weigh and surveil the options well. They find some texts like from Reddit in this case that mention a bunch subset of cases and that text will heavily shape the answer. Which is not what you want a commerce agent to do, you don’t want text prediction. I doubt that gives the obscure but optimal option in most cases.
