A recent comparison of PDF parsing capabilities revealed that Chandra, an OCR model from Datalab, outperformed all other tested parsers, successfully handling merged-cell HTML tables, LaTeX, and even difficult cursive text. While LightOnOCR-1B showed impressive speed and accuracy for its size, it struggled with handwriting and hallucinated content. The comparison included several other parsers like MinerU, Granite-Docling, and PaddleOCR-VL, with varying degrees of success across different document types and challenges. AI
IMPACT Chandra's superior performance sets a new benchmark for PDF parsing, potentially influencing the development and adoption of document understanding tools.
