It’s the big unsolved problem and nobody’s talking about it. I’ve had some decent success asking an expensive model to generate the chunks and combining that with document location, and my next plan for an upcoming project is to do that hierarchically, but there’s no generally accepted solution yet. RAG’s big problem is turning PDFs into chunks, both as a parsing problem and as the chunking problem. I paid someone to do the parsing part into markdown for a project recently (including table data summaries) and it worked well. MathPix has an good API for this, but it only works sensibly for PDFs that don’t have insane layouts, and many do.
