Model Card for Qianfan-OCR-4B-GGUF

This repository contains GGUF format quantizations (Q4_K_M, Q5_K_M, Q6_K, Q8_0) of Qianfan-OCR, a 4B-parameter end-to-end document intelligence model developed by the Baidu Qianfan Team. It unifies document parsing, layout analysis, and document understanding within a single vision-language architecture.

Model Details

Model Description

Qianfan-OCR is designed to replace traditional multi-stage OCR pipelines. Instead of chaining separate layout detection and text recognition modules, it performs direct image-to-Markdown conversion. It introduces Layout-as-Thought, an optional thinking phase where the model generates structured layout representations before producing the final output.

Uses

Direct Use

• Document Parsing: High-fidelity Image-to-Markdown conversion.
• Table/Formula Recognition: Extracting complex tables (merged cells) and LaTeX formulas.
• Key Information Extraction (KIE): Structured data extraction from receipts, invoices, and IDs.
• Visual Question Answering (DocVQA): Reasoning over charts, graphs, and structured documents.

Out-of-Scope Use

• The model is not intended for generating creative fiction or conversational roleplay; it is optimized for high-accuracy document intelligence and visual grounding.

How to Get Started with the Model

1. Requirements

You need both a Quantized Model File (.gguf) and the Vision Projector (qianfan-ocr-mmproj.gguf).
