Logics-Parsing is a powerful, end-to-end document parsing model built upon a general Vision-Language Model (VLM) through Supervised Fine-Tuning (SFT) and Reinforcement Learning (RL). It excels at accurately analyzing and structuring highly complex documents. ## Key Features * **Effortless End-to-End Processing** * Our single-model architecture eliminates the need for complex, multi-stage pipelines. Deployment and inference are straightforward, going directly from a document image to structured output. * It demonstrates exceptional performance on documents with challenging layouts. * **Advanced Content Recognition** * It accurately recognizes and structures difficult content, including intricate scientific formulas. * Chemical structures are intelligently identified and can be represented in the standard **SMILES** format. * **Rich, Structured HTML Output** * The model generates a clean HTML representation of the document, preserving its logical structure. * Each content block (e.g., paragraph, table, figure, formula) is tagged with its **category**, **bounding box coordinates**, and **OCR text**. * It automatically identifies and filters out irrelevant elements like headers and footers, focusing only on the core content. * **State-of-the-Art Performance** * Logics-Parsing achieves the best performance on our in-house benchmark, which is specifically designed to comprehensively evaluate a model’s parsing capability on complex-layout documents and STEM content. ## Benchmark Existing document-parsing benchmarks often provide limited coverage of complex layouts and STEM content. To address this, we constructed an in-house benchmark comprising 1,078 page-level images across nine major categories and over twenty sub-categories. Our model achieves the best performance on this benchmark.
