as somewhat ai curious person, in my experience, with at least small local llm (40-80b) they are absolutely shit at working with large texts, at best they can make a passable summary, contradictory information is ignored (if it’s in two documents), document citations are pulled from the ass 1/3rd of the time (and the pulled info is equally dodgy, if it’s pass/fail type on exactness), is copilot better than this?
