## Release
|
||||
- [2026/01/27]🚀🚀🚀🚀🚀🚀 We present [DeepSeek-OCR2](https://github.com/deepseek-ai/DeepSeek-OCR-2)
|
||||
- [2025/10/23]🚀🚀🚀 DeepSeek-OCR is now officially supported in upstream [vLLM](https://docs.vllm.ai/projects/recipes/en/latest/DeepSeek/DeepSeek-OCR.html#installing-vllm). Thanks to the [vLLM](https://github.com/vllm-project/vllm) team for their help.
|
||||
- [2025/10/20]🚀🚀🚀 We release DeepSeek-OCR, a model to investigate the role of vision encoders from an LLM-centric viewpoint.

## Contents
|
||||
- [Install](#install)
|
||||
- [vLLM Inference](#vllm-inference)
|
||||
- [Transformers Inference](#transformers-inference)
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
## Install
|
||||
>Our environment is cuda11.8+torch2.6.0.
|
||||
1. Clone this repository and navigate to the DeepSeek-OCR folder
|
||||
```bash
|
||||
git clone https://github.com/deepseek-ai/DeepSeek-OCR.git
|
||||
```
|
||||
2. Conda
|
||||
```Shell
|
||||
conda create -n deepseek-ocr python=3.12.9 -y
|
||||
conda activate deepseek-ocr
|
||||
```
|
||||
3. Packages
|
||||
|
||||
- download the vllm-0.8.5 [whl](https://github.com/vllm-project/vllm/releases/tag/v0.8.5)
|
||||
```Shell
|
||||
pip install torch==2.6.0 torchvision==0.21.0 torchaudio==2.6.0 --index-url https://download.pytorch.org/whl/cu118
|
||||
pip install vllm-0.8.5+cu118-cp38-abi3-manylinux1_x86_64.whl
|
||||
pip install -r requirements.txt
|
||||
pip install flash-attn==2.7.3 --no-build-isolation
|
||||
```
|
||||
**Note:** if you want vLLM and transformers codes to run in the same environment, you don't need to worry about this installation error like: vllm 0.8.5+cu118 requires transformers>=4.51.1

|
||||
|
||||
```shell
|
||||
uv venv
|

## Transformers-Inference
|

- Transformers
|
||||
```python
|

from transformers import AutoModel, AutoTokenizer
|
||||
import torch
|
||||
import os
|
||||
os.environ["CUDA_VISIBLE_DEVICES"] = '0'
|
||||
model_name = 'deepseek-ai/DeepSeek-OCR'
|
||||
|
||||
tokenizer = AutoTokenizer.from_pretrained(model_name, trust_remote_code=True)
|
||||
model = AutoModel.from_pretrained(model_name, _attn_implementation='flash_attention_2', trust_remote_code=True, use_safetensors=True)
|
||||
model = model.eval().cuda().to(torch.bfloat16)
|
||||
|
||||
# prompt = "<image>\nFree OCR. "
|
||||
prompt = "<image>\n<|grounding|>Convert the document to markdown. "
|
||||
image_file = 'your_image.jpg'
|
||||
output_path = 'your/output/dir'
|
||||
|
||||
res = model.infer(tokenizer, prompt=prompt, image_file=image_file, output_path = output_path, base_size = 1024, image_size = 640, crop_mode=True, save_results = True, test_compress = True)
|
||||
```
|
||||
or you can
|
||||
```Shell
|
||||
cd DeepSeek-OCR-master/DeepSeek-OCR-hf
|
||||
python run_dpsk_ocr.py
|
||||
```
|
||||
## Support-Modes
|
||||
The current open-source model supports the following modes:
|
||||
- Native resolution:
|
||||
- Tiny: 512×512 (64 vision tokens)✅
|
||||
- Small: 640×640 (100 vision tokens)✅
|
||||
- Base: 1024×1024 (256 vision tokens)✅
|
||||
- Large: 1280×1280 (400 vision tokens)✅
|
||||
- Dynamic resolution
|
||||
- Gundam: n×640×640 + 1×1024×1024 ✅
|
||||
|
||||
## Prompts examples
|
||||
```python
|
||||
# document: <image>\n<|grounding|>Convert the document to markdown.
|
||||
# other image: <image>\n<|grounding|>OCR this image.
|
||||
# without layouts: <image>\nFree OCR.
|
||||
# figures in document: <image>\nParse the figure.
|
||||
# general: <image>\nDescribe this image in detail.
|
||||
# rec: <image>\nLocate <|ref|>xxxx<|/ref|> in the image.
|
||||
# '先天下之忧而忧'
