Building LLM’s. In my mind those engineers are the ones that have more intimate knowledge of the data and input, and can create the LLM’s for their specific tasks. Everyone else is a customer to them.

I can tell you how a house is built, that doesn’t make me a builder that makes me informed and opinionated. I can decorate my house however I like but im not a painter/decorator or a tradesman. I can assemble some ikea furniture, but I’m not a carpenter. I’m a consumer and I can tweak something to my liking but I can’t do anything significant.
