How would you process documents containing tables, images, and scanned pages for RAG?

I would first define the outcome and acceptable error boundary. I would explicitly cover OCR, layout parsing, modality representation, provenance. I would select an approach only after comparing quality, latency, cost, safety, and operational complexity, then validate it with representative cases and production monitoring.

A second valid approach is to begin with the highest-risk assumption and test it cheaply. I would explicitly cover OCR, layout parsing, modality representation, provenance. I would select an approach only after comparing quality, latency, cost, safety, and operational complexity, then validate it with representative cases and production monitoring.
