Release [2026/10/27] 🚀 We release Unlimited OCR 2 , achieving unlimited-horizon parsing with SR-SWA.What's New in 2 Sparse Reference Sliding Window Attention (SR-SWA): Compresses text-visual attention interactions from ultra-long sequences down to a fixed-size set of working references (e.g., 512 tokens).

This bounds computational complexity, keeping per-step decoding latency and memory footprint nearly constant regardless of document length.From Long- to Unlimited-Horizon Parsing: Powered by SR-SWA, Unlimited-OCR 2 achieves true, unbounded document parsing within a finite context window—effectively eliminating quadratic attention scaling and memory bottlenecks as documents grow.

Ultra-Long Document Parsing SOTA: Achieves state-of-the-art performance across both dozens-of-pages benchmarks (e.g., MPDocBench) and extreme hundred-page benchmarks (e.g., MarathonDocBench).submitted by /u/pmttyji [link] [comments]
