Baidu releases MarathonDocBench, a benchmark for 100–300-page document parsing

Baidu releases MarathonDocBench, a benchmark for parsing Chinese and English documents of 100 to 300 pages, under an Apache-2.0 License, according to ModelScope's post on X. The benchmark contains about 18,000 pages and 205,000 annotated layout elements, with human-refined annotations for bounding boxes, heading hierarchy, reading order, and text and table continuations across pages.

Under the published whole-document protocol, which counts failed requests as empty predictions, listed general-purpose vision-language models score below 34 Overall.
