Baidu open-sources Unlimited OCR 2 for parsing documents of any length

AIBaidu releases Unlimited OCR 2 as an open-source model that parses documents of virtually any length within a finite context window. Its SR-SWA mechanism condenses text-visual attention into a fixed-size set of working references, keeping per-step decoding latency and memory nearly constant as documents grow.

Unlimited OCR 2 is here, and it's open source. 📖 ✨

Longer documents can mean a lot more attention computation. Our new SR-SWA mechanism keeps that in check by condensing text-visual attention interactions into a fixed-size set of working references.

Here's what it delivers:
- Document parsing at virtually any length, within a finite context window
- Nearly constant per-step decoding latency and memory footprint as documents grow longer
- State-of-the-art performance on MPDocBench and MarathonDocBench, covering documents from dozens to hundreds of pages
