One RAG Pipeline, Four Very Different PDFs: Same Four Bricks, Every Answer Typed and Cited

An enterprise RAG pipeline can be constructed from four upgraded components wired into a single, powerful function. These four "bricks" systematically handle document parsing, question parsing, information retrieval, and final answer generation to deliver a typed, cited answer. The true test of the system's power is its ability to process vastly different PDF documents, from research papers to reports with broken tables of contents, using the exact same code. This advanced pipeline also incorporates sophisticated side channels, including a feedback loop from generation back to retrieval, to continuously refine results and improve accuracy.
