## PP-OCRv6 Overview
PP-OCRv6 is a lightweight OCR system that combines architectural innovation with data-centric optimization. It redesigns the backbone, detection neck, and recognition neck around a unified MetaFormer-style building block with structural reparameterization. Three model tiers (medium, small, tiny) share the same block primitives, covering deployment scenarios from server to edge.
### Key Features
1. **Unified and Scalable Model Family:** A three-tier OCR model family spanning 1.5M to 34.5M parameters. PP-OCRv6_medium achieves 86.2% detection Hmean and 83.2% recognition accuracy, outperforming PP-OCRv5_server by +4.6% and +5.1% respectively.
2. **Lightweight Architectural Innovations:** (i) LCNetV4, a MetaFormer-style lightweight backbone with structural reparameterization; (ii) RepLKFPN, a detection neck with dilated reparameterizable depthwise convolutions; (iii) EncoderWithLightSVTR, a recognition neck with local-global attention and additive skip connections.
3. **Multi-Language and Scenario Support:** Supports 50 languages and diverse industrial scenes (digital displays, dot-matrix characters, tire prints, etc.), surpassing Qwen3-VL-235B, GPT-5.5, and Gemini-3.1-Pro with orders of magnitude fewer parameters.

PP-OCRv6 text recognition architecture overview
</div>
PP-OCRv6_medium_rec is the largest recognition model in the PP-OCRv6 series. It uses LCNetV4 as the backbone and EncoderWithLightSVTR as the recognition neck, with a CTC+NRTR multi-head decoder. The model supports 50 languages and contains 19M parameters. The key accuracy metrics are as follows:

## Quick Start
### Installation
1. PaddleOCR
```bash
# Install the basic version
pip install paddleocr
# Install the full version (includes all features)
pip install "paddleocr[all]"
```
2. Transformers environment (required for safetensors models)
```bash
pip install transformers torch
```
### Model Usage
You can quickly experience the functionality with a single command:
```bash
paddleocr text_recognition \
--model_name PP-OCRv6_medium_rec \
--engine transformers \
-i https://cdn-uploads.huggingface.co/production/uploads/681c1ecd9539bdde5ae1733c/2PZfbirjfxA88695lRmgk.jpeg
```
You can also integrate the model inference of the text recognition module into your project. Before running the following code, please download the sample image to your local machine.
```python
from paddleocr import TextRecognition
model = TextRecognition(model_name="PP-OCRv6_medium_rec", engine="transformers")
output = model.predict(input="2PZfbirjfxA88695lRmgk.jpeg", batch_size=1)
for res in output:
res.print()
res.save_to_json(save_path="./output/res.json")
```
After running, the obtained result is as follows:
```json
{'res': {'input_path': '2PZfbirjfxA88695lRmgk.jpeg', 'page_index': None, 'rec_text': 'day as a reminder of the', 'rec_score': 0.9857}}
```

For details about usage command and descriptions of parameters, please refer to the [Document](https://paddlepaddle.github.io/PaddleOCR/latest/en/version3.x/module_usage/text_recognition.html).
### Pipeline Usage
The general OCR pipeline is used to solve text recognition tasks by extracting text information from images. The pipeline consists of several modules:
* Document Image Orientation Classification Module (Optional)
* Text Image Unwarping Module (Optional)
* Text Line Orientation Classification Module (Optional)
* Text Detection Module
* Text Recognition Module
Run a single command to quickly experience the OCR pipeline:
```bash
paddleocr ocr -i https://cdn-uploads.huggingface.co/production/uploads/681c1ecd9539bdde5ae1733c/3ul2Rq4Sk5Cn-l69D695U.png \
--text_detection_model_name PP-OCRv6_medium_det \
--text_recognition_model_name PP-OCRv6_medium_rec \
--engine transformers \
--use_doc_orientation_classify False \
--use_doc_unwarping False \
--use_textline_orientation True \
--save_path ./output \
--device gpu:0
```
If save_path is specified, the visualization results will be saved under `save_path`. The visualization output is shown below:
For project integration:
```python
from paddleocr import PaddleOCR
ocr = PaddleOCR(
text_detection_model_name="PP-OCRv6_medium_det",
text_recognition_model_name="PP-OCRv6_medium_rec",
engine="transformers",
use_doc_orientation_classify=False,
use_doc_unwarping=False,
use_textline_orientation=True,
)
result = ocr.predict("./3ul2Rq4Sk5Cn-l69D695U.png")
for res in result:
res.print()
res.save_to_img("output")
res.save_to_json("output")
```
