OpenBMB open-sources MiniCPM-OCR: 1.3B model parses 128 pages per minute

haider1 · x · 2026-10-31

OpenBMB released MiniCPM-OCR, an open-source (Apache-2.0) OCR model family with two components. MiniCPM-OCR 1.0 (1.3B) parses Chinese and English documents and PDFs, handling scans, photos, curved pages, and recaptured documents at up to 128 pages per minute with its optimized SDK. MiniCPM-OCR Jev (2B) evaluates OCR results at the region level, flagging unreliable regions for review and working alongside different parsing models. The author's test—running OCR through 1.0 and verifying accuracy with Jev—showed impressive results for models this size, supporting the thesis that small specialized models will take over tasks once requiring much larger systems. Free API, web demo, and local deployment are available; the repo has 640 stars.
