Tencent's WeVisDoc-4B converts a page image into structured Markdown, with LaTeX formulas and HTML tables. Its model card reports 69.08 on the real-degraded-document track of PureDocBench, compared with 65.60 for the 2B version. On the cleaner OmniDocBench v1.6 the gap is small, 95.38 against 95.06, so the larger model's reported advantage is clearest on degraded pages. Document-processing teams whose inputs are damaged have a concrete reason to test the larger model. These are developer-reported scores.
