OpenBMB open-sources the MiniCPM-OCR suite: a 1.3B parser scoring 93.68 on Real5-OmniDocBench, plus a 2B judge model that flags OCR errors
On Oct 27 OpenBMB (ModelBest) open-sourced the MiniCPM-OCR suite with two models: MiniCPM-OCR 1.0, a 1.3B-parameter document parser that scores 93.68 on Real5-OmniDocBench and 54.7 on OCRBench v2 (vendor-reported), and MiniCPM-OCR Jev, a 2B OCR quality judge that scores any parser's output region by region from 0 to 1 and flags content that needs human review. Code and weights are Apache 2.0, with day-one support for vLLM, SGLang, llama.cpp, Ollama and multiple chip platforms.

Key Takeaways
- MiniCPM-OCR 1.0 has just 1.3B parameters and scores 93.68 on Real5-OmniDocBench and 54.7 on OCRBench v2 (vendor-reported, both claimed SOTA)
- The 2B MiniCPM-OCR Jev judge reaches 93.6 AUROC on JevOCRBench, above JEV-35B-A3B at 90.1 and close to Qwen3.5-397B-A17B at 93.8 (vendor-reported)
- Jev is parser-agnostic: AUROC stays between 91.9 and 93.4 on outputs from MiniCPM-OCR, GLM-OCR, PaddleOCR-VL-1.6 and Xiaomi-OCR-0
- Throughput is about 1.49x PaddleOCR-VL-1.6 and 3.62x MinerU2.5 Pro, reaching up to about 128 pages per minute with SDK concurrency (vendor-reported)
- Code and weights on GitHub are all Apache 2.0, with GGUF/AWQ/GPTQ quantized builds and a SKILL.md for coding agents
