Baidu releases Unlimited-OCR-2 for documents that span many pages
Baidu's October 27th release tackles document extraction with a bounded working memory and sliding attention rather than letting every page accumulate in an ever-growing context. It pairs the model with a long-document evaluation resource, MarathonDocBench.
The useful claim is that resource use can remain manageable across long documents while preserving references across pages. The name does not guarantee accurate extraction from arbitrarily long files. Tables, page boundaries and cross-page references still need testing on the documents a buyer actually uses. SourcesA
