Document Parsing and Visual Retrieval for Production RAG: Architecture, Benchmarks, and Serving Trade-Offs for Docling, Marker, MinerU, and ColPali

Document Parsing and Visual Retrieval for Production RAG: Architecture, Benchmarks, and Serving Trade-Offs for Docling, Marker, MinerU, and ColPali The retrieval quality of a Retrieval-Augmented Generation (RAG) system is strictly bounded by the fidelity of its document ingestion pipeline. In enterprise environments, the vast majority of domain knowledge remains locked in unstructured Portable Document Format (PDF) files, scanned reports, technical manuals, and multi-column research papers.
