SoMark released OXR, an open-source 1.3B document parsing model that ranks #1 on olmOCR-Bench, OmniDocBench, and DocParsingBench. It converts PDFs and document images into Markdown/JSON with layout coordinates, handling tables, stamps, and 11 other element types for agent-friendly output. It's the first doc parser to use a recursive self-improvement (RSI) loop in post-training, and its layout module is replaceable. Benchmarked on a single RTX PRO 6000, it parsed 100 OmniDocBench pages in 101s versus MinerU2.5-Pro's 254.7s — the fastest among open-source parsers tested. Offers an online demo and free API.
