Alibaba has open-sourced Logics-Parsing-V3, a 0.8B VLM for structured long-document parsing.
Instead of resetting at every page, it carries a compact structural state forward as it reads — preserving context across pages without putting the entire document into one context window.
This lets it recover document hierarchy, merge content split across pages, and link visual elements to related text in a single end-to-end model.
It also handles complex layouts, scientific formulas, and chemical notation.
On MPDocBench-Parse, it scores 85.26, ranking #
