  • RAG-Anything: Multimodal Document Retrieval Is Not Just Text Conversion

    Intermediate Retrieval, memory, and production RAG
    RAG-Anything Deep Dive · Part 1 · Note · Mar 23, 2026 · Paper · 2025 · NLP

    A source-grounded reading of RAG-Anything's dual graph, experimental evidence, failure cases, artifact status, and engineering adoption boundary.

    Understand it in 90 seconds
    Problem
    Traditional approaches often collapse figures and tables into captions, losing cells, panels, axes, and cross-page relationships.
    Core insight
    Use textual proxies for retrieval while preserving dereferenceable raw artifacts; combine explicit graph relations with dense similarity to find evidence.
    Strongest evidence
    Tables 2–4 and Figure 2 show an overall lead, attribute most of the gain to graph construction, and show a larger gap on long-document slices.
    Main boundary
    Abstention, parser errors, entity alignment, cost, and latency are not solved by aggregate accuracy.
