I compared MinerU, Granite-Docling, and PaddleOCR-VL on 12 PDF-parsing capabilities using 6 document types

What it means

This is a user-conducted benchmark on Reddit comparing three open-source PDF parsing tools: MinerU (by OpenDataLab), Granite-Docling (IBM's document understanding toolkit), and PaddleOCR-VL (Baidu's vision-language OCR model). The test covers 12 specific parsing capabilities (e.g., table extraction, layout detection, OCR accuracy) across 6 document types (e.g., scientific papers, invoices, forms). The post likely presents raw performance metrics and qualitative observations, but the exact results are not detailed here.

Accuracy & sources

The claim is a first-person report from the Reddit user who ran the comparison, making it a primary source for that user's own findings. However, there is no independent verification or peer review; the methodology, dataset, and reproducibility are not confirmed from this snippet. The provenance tier is correctly labeled as primary source, but the reliability depends on the user's rigor.
