Datalab's Marker 2 Hits 76.0 on olmOCR-Bench at 5x MinerU's Throughput

Datalab has released Marker 2, a document parsing tool that scores 76.0 on the olmOCR-bench and processes documents at five times the throughput of MinerU, outperforming competitors including Docling and LiteParse. This positions Marker 2 as a leading open-source option for high-volume document ingestion pipelines, a common bottleneck in RAG and enterprise AI workflows. The benchmark results matter because olmOCR-bench tests real-world document understanding across complex layouts, making the score a meaningful signal of production-readiness. Developers building document-heavy applications — legal, finance, healthcare, or general knowledge base construction — should benchmark Marker 2 against their current stack. The throughput advantage in particular is significant for teams processing large document corpora where latency and cost are constraints.
