Open-source OCR from Baidu eliminates the GPU memory wall that limits long-document parsing. Unlimited OCR uses a constant KV cache to process entire books on a single GPU in one forward pass, scoring approximately 93 on OmniDocBench and 35 percent faster than DeepSeek OCR at long output lengths. Developers should note Baidu is subject to China's National Intelligence Law.
