I've been confused by this with many LLM products in general. Sometimes infrastructure is part of it so there's that, but often it seems like the product is a magic incantation of markdown files.
Here I'm mostly considering the seemingly countless services that are little more than some markdown files and their own API passing data to/from the LLM procider's API.
By no means is that every AI product today, and I wasn't saying the OP QA service falls into that bucket though.
More of a general comment related to the GP, maybe too off topic here though?
