Baidu releases Unlimited-OCR 2 for unbounded document parsing
Baidu released Unlimited-OCR 2, built on Sparse Reference Sliding Window Attention (SR-SWA), which compresses text-visual attention into a fixed-size reference set (e.g., 512 tokens) so decoding latency and memory stay nearly constant regardless of document length. It claims state-of-the-art results on benchmarks such as MPDocBench and the hundred-page MarathonDocBench.
