🚀 Introduction

Since its initial release, PaddleOCR has gained widespread acclaim across academia, industry, and research communities, thanks to its cutting-edge algorithms and proven performance in real-world applications. It’s already powering popular open-source projects like Umi-OCR, OmniParser, MinerU, and RAGFlow, making it the go-to OCR toolkit for developers worldwide.

On May 20, 2025, the PaddlePaddle team unveiled PaddleOCR 3.0, fully compatible with the official release of the PaddlePaddle 3.0 framework. This update further boosts text-recognition accuracy, adds support for multiple text-type recognition and handwriting recognition, and meets the growing demand from large-model applications for high-precision parsing of complex documents. When combined with the ERNIE 4.5T, it significantly enhances key-information extraction accuracy. PaddleOCR 3.0 also introduces support for domestic hardware platforms such as KUNLUNXIN and Ascend. For the complete usage documentation, please refer to the PaddleOCR 3.0 Documentation.

Three Major New Features in PaddleOCR 3.0:

• Universal-Scene Text Recognition Model PP-OCRv5: A single model that handles five different text types plus complex handwriting. Overall recognition accuracy has increased by 13 percentage points over the previous generation. Online Demo

• General Document-Parsing Solution PP-StructureV3: Delivers high-precision parsing of multi-layout, multi-scene PDFs, outperforming many open- and closed-source solutions on public benchmarks. Online Demo

• Intelligent Document-Understanding Solution PP-ChatOCRv4: Natively powered by the WenXin large model 4.5T, achieving 15 percentage points higher accuracy than its predecessor. Online Demo

In addition to providing an outstanding model library, PaddleOCR 3.0 also offers user-friendly tools covering model training, inference, and service deployment, so developers can rapidly bring AI applications to production.

📣 Recent updates

🔥🔥 2025.06.05: Release of PaddleOCR 3.0.1, includes:

• Optimisation of certain models and model configurations:

  • Updated the default model configuration for PP-OCRv5, changing both detection and recognition from mobile to server models. To improve default performance in most scenarios, the parameter limit_side_len in the configuration has been changed from 736 to 64.
  • Added a new text line orientation classification model PP-LCNet_x1_0_textline_ori with an accuracy of 99.42%. The default text line orientation classifier for OCR, PP-StructureV3, and PP-ChatOCRv4 pipelines has been updated to this model.
  • Optimised the text line orientation classification model PP-LCNet_x0_25_textline_ori, improving accuracy by 3.3 percentage points to a current accuracy of 98.85%.

• Optimizations and fixes for some issues in version 3.0.0, details

  2. 🧠 Specialized capabilities include seal recognition, chart-to-table conversion, table recognition with nested formulas/images, vertical text document parsing, and complex table structure analysis.

• PP-ChatOCRv4: Intelligent Document Understanding – Extract Key Information, not just text from Images/PDFs.

  1. 🔥 15-point accuracy gain in key-information extraction on PDF/PNG/JPG files over the previous generation.
  2. 💻 Native support for ERINE4.5 Turbo, with compatibility for large-model deployments via PaddleNLP, Ollama, vLLM, and more.
  3. 🤝 Integrated PP-DocBee2, enabling extraction and understanding of printed text, handwriting, seals, tables, charts, and other common elements in complex documents.

The history of updates

• 🔥🔥2025.03.07: Release of PaddleOCR v2.10, including:

  • 12 new self-developed models:
    • Layout Detection series(3 models): PP-DocLayout-L, M, and S -- capable of detecting 23 common layout types across diverse document formats(papers, reports, exams, books, magazines, contracts, etc.) in English and Chinese. Achieves up to 90.4% mAP@0.5 , and lightweight features can process over 100 pages per second.
    • Formula Recognition series(2 models): PP-FormulaNet-L and S -- supports recognition of 50,000+ LaTeX expressions, handling both printed and handwritten formulas. PP-FormulaNet-L offers 6% higher accuracy than comparable models; PP-FormulaNet-S is 16x faster while maintaining similar accuracy.
    • Table Structure Recognition series(2 models): SLANeXt_wired and SLANeXt_wireless -- newly developed models with 6% accuracy improvement over SLANet_plus in complex table recognition.
    • Table Classification(1 model): PP-LCNet_x1_0_table_cls -- an ultra-lightweight classifier for wired and wireless tables.
