Yes, i have. The problem with using just an LLM is that while it reads and understands text, but it cannot reproduce it accurately. Additionaly the textbooks I've mentioned have many diagrams and illustrations in them (e.g. books on anatomy or biochemistry). I don't really care about extracting text from them, I just need them extracted as images alongside the text, and no LLM does that.
Great progress, but unfortunately, for our use case (converting medical textbooks from PDF to MD), the results are not as good as those by MinerU/PDF-Extract-Kit [1].
Also the collab link in the article is broken, found a functional one [2] in the docs.
