Slightly off topic: what’s the reasonably smallest LLM model i can use to do language processing and rewriting of a large library of word documents? For the purposes of querying information and regurgitating out summaries or detailed information? My use case is very simple: take 1000 word documents filled with two to three pages of information and pictures. And then output a set of requested information via prompting. Is there something off the shelf? Or do I have to make this?
