Baidu's Unlimited-OCR reads a 100-page PDF in one pass without exploding VRAM (github.com)
Baidu open-sourced Unlimited-OCR, which parses long documents in one pass instead of chopping them into pages and gluing the text back. The trick (R-SWA): keep the full document image always in view, but cap memory of the model's own output to a small sliding window so the KV cache stops growing.
It openly credits DeepSeek-OCR and PaddleOCR for the ideas. The thread's skeptics ask the obvious thing: how is this better than just feeding one page at a time?
