China has open-sourced a peanut-sized OCR that can parse an entire 100-page PDF at once.
It’s called ‘Unlimited-OCR’. Only 3B parameters. Runs locally.
Other OCR tools split documents page by page, easily losing context. This one reads the entire document in one go.
→ Single ‘long-vision’ parsing (32K context window)
→ Out-of-the-box multilingual support
→ 93% accuracy on standard benchmarks (+6 above baseline)
→ <0.11 error rate on 40+ pages
→ 100% local execution
→ Supports Transformers, vLLM, SGLang, Docker, Ollama, llama.cpp
Traditional cloud OCR (Textract, Google Vision, Azure) costs 1.5–15 per thousand pages.
This runs on your machine. Free forever.
Developed by Baidu to advance ‘DeepSeek-OCR’. Already 1.9 million downloads on Hugging Face, but most people still don’t know about it.
100% open-source.
