DeepSeek-OCR: Contexts Optical Compression

Explore the boundaries of visual-text compression.

Release

• [2026/01/27]🚀🚀🚀🚀🚀🚀 We present DeepSeek-OCR2
• [2025/10/23]🚀🚀🚀 DeepSeek-OCR is now officially supported in upstream vLLM. Thanks to the 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

git clone https://github.com/deepseek-ai/DeepSeek-OCR.git

2. Conda

conda create -n deepseek-ocr python=3.12.9 -y
conda activate deepseek-ocr

3. Packages

• download the vllm-0.8.5 whl

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

vLLM-Inference

• VLLM:

>Note: change the INPUT_PATH/OUTPUT_PATH and other settings in the DeepSeek-OCR-master/DeepSeek-OCR-vllm/config.py

cd DeepSeek-OCR-master/DeepSeek-OCR-vllm

1. image: streaming output

python run_dpsk_ocr_image.py

2. pdf: concurrency ~2500tokens/s(an A100-40G)

python run_dpsk_ocr_pdf.py

3. batch eval for benchmarks

python run_dpsk_ocr_eval_batch.py

[2025/10/23] The version of upstream [vLLM](https://docs.vllm.ai/projects/recipes/en/latest/DeepSeek/DeepSeek-OCR.html#installing-vllm):

uv venv
source .venv/bin/activate
# Until v0.11.1 release, you need to install vLLM from nightly build
uv pip install -U vllm --pre --extra-index-url https://wheels.vllm.ai/nightly

Transformers-Inference

• Transformers

from transformers import AutoModel, AutoTokenizer
import torch

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 = "\nFree OCR. "
prompt = "\nConvert 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

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

# document: \nConvert the document to markdown.
# other image: \nOCR this image.
# without layouts: \nFree OCR.
# figures in document: \nParse the figure.
# general: \nDescribe this image in detail.
# rec: \nLocate xxxx in the image.
# '先天下之忧而忧'
