I’d have to hunt, but there is evidence that using the vocabulary of an expert versus a layman will produce better results. Which makes sense since places where people talk “normally” in spaces are more likely to be incorrect. Whereas in places where people speak in the in the professional vernacular they are more likely to be correct. And the training will associate them together in their spaces.
At their heart, these are still just document-completion machines. Very clever ones, but still inherently trying to find a continuation that matches the part that came before.
This seems right to me. I often ask questions in two phases to take advantage of this (1) How would a professional in the field ask this question? Then (2) paste that question into a new chat.
