What is Unlimited-OCR-2?

Baidu’s Unlimited-OCR 2 reads any length of scanned text, from a single page to hundreds of pages, without slowing down. It uses Sparse Reference Sliding Window Attention to keep memory use and latency fixed regardless of document size.

Who it is for

Developers building document-processing pipelines can now run OCR on ultra-long PDFs without hitting hardware limits.
