Model Card

Qianfan OCR Fast is a document intelligence model from Baidu's Qianfan team, purpose-built for optical character recognition tasks. It is an upgraded variant of the base Qianfan-OCR, trained on specialized OCR data while retaining general multimodal capabilities.

The underlying Qianfan-OCR architecture is a 4B-parameter end-to-end vision-language model that replaces traditional multi-stage OCR pipelines with a single model handling document parsing, layout analysis, table extraction, chart understanding, key information extraction, and document QA. It performs direct image-to-Markdown conversion and supports 192 languages. The base model scored 93.12 on OmniDocBench v1.5 and 79.8 on OlmOCR Bench, leading all end-to-end models on both.

Qianfan OCR Fast offers a 65K-token context window and is well suited for developers building document processing pipelines — invoice parsing, report extraction, exam grading, or RAG over scanned documents.
