Model Information

DeepSeek-OCR is a state-of-the-art document OCR model that excels at:

• 📐 LaTeX equations - Mathematical formulas preserved in LaTeX format
• 📊 Tables - Extracted and formatted as HTML/markdown
• 📝 Document structure - Headers, lists, and formatting maintained
• 🖼️ Image grounding - Spatial layout and bounding box information
• 🔍 Complex layouts - Multi-column and hierarchical structures
• 🌍 Multilingual - Supports multiple languages

Resolution Modes

• Tiny (512×512): Fast processing, 64 vision tokens
• Small (640×640): Balanced speed/quality, 100 vision tokens
• Base (1024×1024): High quality, 256 vision tokens
• Large (1280×1280): Maximum quality, 400 vision tokens
• Gundam (dynamic): Adaptive multi-tile processing for large documents

Dataset Structure

The dataset contains all original columns plus:

• markdown: The extracted text in markdown format with preserved structure
• inference_info: JSON list tracking all OCR models applied to this dataset

Usage

from datasets import load_dataset
import json

# Load the dataset
dataset = load_dataset("{{output_dataset_id}}", split="train")

# Access the markdown text
for example in dataset:
    print(example["markdown"])
    break

# View all OCR models applied to this dataset
inference_info = json.loads(dataset[0]["inference_info"])
for info in inference_info:
    print(f"Column: {{info['column_name']}} - Model: {{info['model_id']}}")

Reproduction

This dataset was generated using the uv-scripts/ocr DeepSeek OCR vLLM script:

uv run https://huggingface.co/datasets/uv-scripts/ocr/raw/main/deepseek-ocr-vllm.py \\
    davanstrien/ency-test \\
    <output-dataset> \\
    --resolution-mode large \\
    --image-column image

Performance

• Processing Speed: ~0.2 images/second
• Processing Method: Batch processing with vLLM (2-3x speedup over sequential)
