Summary

China released Unlimited-OCR, a 3-billion-parameter open-source optical character recognition model that can process entire 100-page PDFs in a single pass with 32K context window, eliminating the page-by-page limitations of traditional OCR tools. The model achieves 93% accuracy on parsing benchmarks, runs entirely locally for free, and supports multiple languages, positioning it as a free alternative to expensive cloud-based OCR services like AWS Textract and Google Vision.

    China open-sourced a peanut-sized OCR that parses entire 100-page PDFs in one shot.. It's called Unlimited-OCR. Only 3B params. Runs locally. Every other OCR tool chops your doc into pages and loses the thread. this one reads the whole thing in a single pass. → One-shot "long-horizon" parsing (32K context window) → Multilingual, out of the box → 93% on the standard parsing benchmark (+6 over baseline) → <0.11 error rate past 40 pages → Runs 100% locally on your own hardware → Works with Transformers, vLLM, SGLang, Docker, Ollama, llama.cpp Traditional cloud OCR (Textract, Google Vision, Azure Doc Intelligence) costs $1.50–$15 per 1,000 pages. This runs on your machine. For free. Forever. Baidu built it explicitly to push DeepSeek-OCR one step further. Already at 1.9M downloads on Hugging Face and most people have no idea it exists yet. 100% open source.
