What is PaddleOCR-VL?
PaddleOCR-VL-0.9B is an ultra-lightweight Vision-Language Model released by Baidu's PaddlePaddle team in October 2025, specifically optimized for document parsing scenarios. It is one of the most powerful derivative models in the ERNIE-4.5 series.
Core Features
1. Extreme Parameter Efficiency
- Only 0.9B (900 million) parameters
- Can run on regular CPUs
- Supports browser plugin-level deployment
- Extremely low memory footprint
2. SOTA-Level Performance
- Ranked #1 globally on OmniBenchDoc V1.5
- Leads comprehensively in four core capabilities (text, tables, formulas, reading order)
- Surpasses 72B-level large models
3. True Document Understanding
- Not just text recognition, but document structure comprehension
- Intelligently handles multi-column layouts, complex tables, mathematical formulas
- Supports handwritten note recognition
- Can extract special elements (QR codes, stamps, charts)
π‘ Why Can a Small Model Surpass Large Models?
PaddleOCR-VL adopts an architecture specifically optimized for OCR tasks rather than pursuing general capabilities. This "specialization" strategy enables it to achieve extreme efficiency and accuracy in the document parsing domain.
Core Technical Architecture
Technical Components
PaddleOCR-VL consists of three core components:
Component | Technical Solution | Function |
---|---|---|
Vision Encoder | NaViT Dynamic Resolution Encoder | Processes document images of different sizes while maintaining high-resolution details |
Language Model | ERNIE-4.5-0.3B | Lightweight yet powerful language understanding capability |
Fusion Mechanism | Vision-Language Cross-modal Alignment | Converts image information into structured text |
Advantages of NaViT Dynamic Vision Encoder
- Adaptive Resolution: Dynamically adjusts processing precision based on document complexity
- Detail Preservation: Doesn't lose small text or complex symbols due to scaling
- Efficient Inference: Saves 30% computational resources compared to fixed-resolution solutions
β Technical Highlight
The integration of ERNIE-4.5-0.3B is the key to success β both intelligent and scalable.

Special Scenario: Invoice Recognition
According to testing by Chinese community user @karminski3:
"I threw in an invoice to test it! Holy crap, SOTA! Not only is the OCR recognition accurate, it can even extract QR codes and stamps separately! Table reconstruction is also very accurate!"
Invoice Recognition Capabilities:
- β Accurately recognizes invoice numbers, dates, amounts
- β Extracts tabular line items

Selected Community Feedback
International Developer Community
Reddit r/LocalLLaMA Hot Discussion
u/Few_Painter_5588: "PaddleOCR is probably the best OCR framework. It's shocking how no other OCR framework comes close."
Important Note on Image Resolution: "As long as your image is around 1080p, it works pretty well. I was running it on 4k and 1440p images and it was missing most of the text. When I resized it to 1080p, worked like a charm."
u/the__storm: "Vertical text support should be pretty good - I believe it's explicitly addressed in the paper. (This is a model from Baidu (Chinese) so support for vertical writing was definitely a consideration.)"
u/Briskfall: "Wait, Paddle beat Gemini and Qwen?! Urgh- time to test them again..."
X (Twitter) Community Response
@karminski3 (Chinese Developer): "Baidu! Baidu is standing tall! Come check out PaddleOCR-VL! I had zero expectations seeing it was just a 0.9B model, but I threw in an invoice to test it! Holy crap, SOTA! Not only is the OCR recognition accurate, it can even extract QR codes and stamps separately! Table reconstruction is also very accurate! Most importantly, this thing is only 0.9B! Can be directly embedded in browsers as a plugin!"
@manish Kumar Shah: "Document understanding just reached a new level. ERNIE-4.5-0.3B integration seems to be the secret sauce here β smart and scalable."
@Parul_Gautam7: "#1 globally on the OmniBenchDoc V1.5 leaderboard with a composite score of 90.67. Built for the real world, PaddleOCR-VL handles the messiness of real-world documents with ease."
Chinese User Real-World Feedback: "Our company has been using PaddleOCR for text recognition for several years, very stable! Just compared PaddleOCR-VL with ChatGPT, Gemini, and Doubao, took a super blurry photo with my phone and had them recognize it, PaddleOCR-VL crushed them directly, total win!"
Key Evaluation Summary
Consensus on Advantages:
- β Achieves SOTA level in the OCR domain
- β Big capabilities in a small model, deployment-friendly

π€ Frequently Asked Questions
Q1: What languages does PaddleOCR-VL support?
A: Supports 109 languages, including Chinese, English, Japanese, Korean, French, German, Spanish, Russian, Arabic, Hindi, Thai, and other major languages, as well as many minority languages.
Q2: Can it run on CPU?
A: Yes! PaddleOCR-VL-0.9B has an extremely small parameter count and can run on regular CPUs, although it will be slower than GPU but still usable.
Q3: How to handle ultra-high resolution images?
A: Based on community feedback, it's recommended to scale 4K or higher resolution images to the 1080p-2K range for optimal recognition results.
Q4: Can it recognize handwritten content?
A: Yes, it can recognize handwritten content, but for very messy handwriting, large VLMs (like GPT-4o) may perform better as they can "guess" hard-to-read words through context.
Q5: What are the advantages compared to GPT-4o?
A: Main advantages include:
- Local deployment possible, no API calls needed
- Faster inference speed
- Free and open source
- Higher accuracy in document parsing tasks
- But GPT-4o is more powerful for general tasks
Q6: How to integrate with existing projects?
A: PaddleOCR-VL has been adopted by several well-known open source projects, including RAGFlow, MinerU, Umi-OCR, OmniParser, etc. You can refer to these projects' integration methods or use the Python API directly.
Q7: Does the model hallucinate?
A: Yes. Like all modern OCR systems, PaddleOCR-VL may also hallucinate (recognize non-existent content), but this is relatively rare.
Q8: Does it support vertical text recognition?
A: Yes. Since this is a model developed by Baidu (China), support for vertical writing (such as vertical Chinese and Japanese) is an explicitly considered feature.
