Read our Guide How to: Run & Fine-tune DeepSeek-OCR 2.
- Fine-tune DeepSeek-OCR 2 for free using our Google Colab notebook
- View the rest of our notebooks in our docs here.
Usage
Inference using Huggingface transformers on NVIDIA GPUs. Requirements tested on python 3.12.9 + CUDA11.8：
torch==2.6.0
transformers==4.46.3
tokenizers==0.20.3

Support-Modes
- Dynamic resolution
- Default: (0-6)×768×768 + 1×1024×1024 — (0-6)×144 + 256 visual tokens ✅
Prompts examples
# 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.
