English(EN) Baidu Open-Sources Unlimited OCR 2 for Hundred-Page Document Parsing

百度发布Unlimited OCR 2，用于长文档解析

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-27 05:26

百度发布了Unlimited OCR 2，这是一个开源的光学字符识别模型，专为解析长文档而设计。这个拥有33.4亿参数的模型单次请求即可处理数百页文档，并在MarathonDocBench等基准测试中取得了顶尖性能。其关键创新是SR-SWA，一种稀疏注意力机制，无论文档长度如何都能保持一致的解码成本，从而实现近乎无限的上下文解析。 AI

影响为长文档OCR树立了新标准，有望加速需要大量文本分析的领域的研究和应用开发。

本文如何被排名

Signal score: 34 / 100; Composite score across the factors below. Higher = stronger signal that this story matters right now.
Newsworthiness bucket: Significant; 百度发布前沿模型，附带系统卡和基准测试结果。[lever_c_降级自frontier_release: ic=1 ai=1.0]
Source corroboration: Single-source cluster; Only one publisher covered this so far. Single-source stories can still rank when the publisher is high-authority, but they lack cross-source corroboration.
Topics: model release, product; Editorial topic classification. Feeds into how the story surfaces on /topic/<slug> hub pages and into the per-entity coverage mix.
AI-industry relevance: High; Clearly on-topic for AI-industry coverage.
Story freshness: Breaking (< 6h); Fresh story with cross-source coverage still developing. Ranking may shift as more sources report.
