Baidu drops Unlimited OCR 2 to read entire books at once
Baidu just open-sourced Unlimited OCR 2, a 3B document-parsing model that can ingest thousands of pages in a single request. By revamping attention with SR-SWA, it keeps memory and latency stable over massive documents, automatically stitching together cross-page tables and split text. It easily fits on consumer GPUs, meaning you no longer have to chop books into pieces just to digitize them.
