New OCR benchmark reveals accuracy doesn't guarantee RAG performance

A new benchmark has been developed to evaluate the robustness of Optical Character Recognition (OCR) systems specifically for Retrieval-Augmented Generation (RAG) applications. Current OCR benchmarks using character-level metrics fail to capture how OCR errors impact downstream RAG performance in real-world industrial scenarios. The benchmark includes 11 challenging document types and reveals that high OCR accuracy does not guarantee effective RAG, as structural and semantic errors can lead to significant retrieval failures.
