Introduction

We introduce PaddleOCR-VL-1.6, an upgraded compact document parsing model built upon PaddleOCR-VL-1.5. PaddleOCR-VL-1.6 introduces a region-aware data optimization framework that identifies weak regions from the previous model, applies targeted enhancement to those regions, and improves the reliability of supervision signals. It further adopts a progressive post-training recipe based on curated data selection and reinforcement learning, pushing model performance to a higher level through staged optimization. PaddleOCR-VL-1.6 achieves a new state-of-the-art score of 96.33% on OmniDocBench v1.6, sets new records on OmniDocBench v1.5 and Real5-OmniDocBench as well, and demonstrates strong competitiveness against top-tier VLMs. The model architecture is fully compatible with PaddleOCR-VL-1.5, enabling zero-cost plug-and-play migration.

PaddleOCR-VL-1.6 Usage with llama.cpp

Install Dependencies

Install PaddlePaddle and PaddleOCR:

# The following command installs the PaddlePaddle version for CUDA 12.6. For other CUDA versions and the CPU version, please refer to https://www.paddlepaddle.org.cn/en/install/quick?docurl=/documentation/docs/en/develop/install/pip/linux-pip_en.html
python -m pip install paddlepaddle-gpu==3.2.1 -i https://www.paddlepaddle.org.cn/packages/stable/cu126/
python -m pip install -U "paddleocr[doc-parser]>=3.6.0"

> Please ensure that you install PaddlePaddle framework version 3.2.1 or above, along with the special version of safetensors. For macOS users, please use Docker to set up the environment.

Basic Usage

1. Start the VLM inference server:

```

llama-server \

-m /path/to/PaddleOCR-VL-1.6-GGUF.gguf \

--mmproj /path/to/PaddleOCR-VL-1.6-GGUF-mmproj.gguf \

--port 8080 \

--host 0.0.0.0 \

--temp 0

```

1. Call the PaddleOCR CLI or Python API:

```bash

paddleocr doc_parser \

-i https://paddle-model-ecology.bj.bcebos.com/paddlex/imgs/demo_image/paddleocr_vl_demo.png \

--pipeline_version v1.6 \

--vl_rec_backend llama-cpp-server \

--vl_rec_server_url http://127.0.0.1:8080/v1

```

```python

from paddleocr import PaddleOCRVL

pipeline = PaddleOCRVL(pipeline_version="v1.6", vl_rec_backend="llama-cpp-server", vl_rec_server_url="http://127.0.0.1:8080/v1")

output = pipeline.predict("https://paddle-model-ecology.bj.bcebos.com/paddlex/imgs/demo_image/paddleocr_vl_demo.png")

for res in output:

res.print()

res.save_to_json(save_path="output")

res.save_to_markdown(save_path="output")

```

For more usage details and parameter explanations, see the documentation.

PaddleOCR-VL-1.6-0.9B Usage with llama.cpp

Currently, the PaddleOCR-VL-1.6-0.9B model facilitates seamless inference via the transformers library, supporting comprehensive text spotting and the recognition of complex elements including formulas, tables, charts, and seals. Below is a simple script we provide to support inference using the PaddleOCR-VL-1.6-0.9B model with llama.cpp.

Usage Tips

We have six types of element-level recognition:

• Text recognition, indicated by the prompt OCR:.
• Formula recognition, indicated by the prompt Formula Recognition:.
• Table recognition, indicated by the prompt Table Recognition:.
• Chart recognition, indicated by the prompt Chart Recognition:.
• Seal recognition, indicated by the prompt Seal Recognition:.
• Spotting, indicated by the prompt Spotting:, and need to set image_max_pixels to 1605632:

```

git clone https://github.com/ggml-org/llama.cpp.git

cd llama.cpp

python -m pip install gguf

python ./gguf-py/gguf/scripts/gguf_set_metadata.py /path/to/PaddleOCR-VL-1.6-GGUF/PaddleOCR-VL-1.6-mmproj.gguf clip.vision.image_max_pixels 1605632 --force

# back to default value (1003520):

# python ./gguf-py/gguf/scripts/gguf_set_metadata.py /path/to/PaddleOCR-VL-1.6-GGUF/PaddleOCR-VL-1.6-mmproj.gguf clip.vision.image_max_pixels 1003520 --force

```

llama-cli Usage

llama-cli \
    -m /path/to/PaddleOCR-VL-1.6-GGUF/PaddleOCR-VL-1.6.gguf \
    --mmproj /path/to/PaddleOCR-VL-1.6-GGUF/PaddleOCR-VL-1.6-mmproj.gguf \
    -p 'OCR:' \
    --image 'test_image.jpg'

llama-server Usage

llama-server -m /path/to/PaddleOCR-VL-1.6.gguf --mmproj /path/to/PaddleOCR-VL-1.6-GGUF/PaddleOCR-VL-1.6-mmproj.gguf --temp 0
