Ask HN: Best on device LLM tooling for PDFs?
I've got very used to using the "big" LLMs for analysing PDFs Now llama.cpp has vision support; I tried out PDFs with it locally (via LM Studio) but the results weren't as good as I hoped for. One time it insisted it couldn't do "OCR", but gave me an example of what the data _could_ look like - which was the data. The other major problem is sometimes PDFs are actually made up of images; and it got super confused on those as well. Given this is so new I'm struggling to find any tools which make this easier. 1 comments on Hacker News.
