Convert document images to markdown using HunyuanOCR with vLLM.

HunyuanOCR is a lightweight 1B parameter VLM from Tencent designed for complex
multilingual document parsing. This script uses vLLM for processing.

Features:
- 📝 Full document parsing to markdown
- 📊 Table extraction (HTML format)
- 📐 Formula recognition (LaTeX format)
- 📍 Text spotting with coordinates
- 🔍 Information extraction (key-value, fields, subtitles)
- 🌐 Photo translation
- 🎯 Compact model (1B parameters)

Model: tencent/HunyuanOCR
vLLM: Requires nightly build (trust_remote_code=True)

Note: Due to vLLM V1 engine batching issues with HunyuanOCR, batch_size defaults to 1.

import json

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

# 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](https://huggingface.co/datasets/uv-scripts/ocr) HunyuanOCR script:

```bash
uv run https://huggingface.co/datasets/uv-scripts/ocr/raw/main/hunyuan-ocr.py \\
    {source_dataset} \\
    <output-dataset> \\
    --image-column {image_column} \\
    --batch-size {batch_size} \\
    --prompt-mode {prompt_mode} \\
    --max-model-len {max_model_len} \\
    --max-tokens {max_tokens} \\
    --gpu-memory-utilization {gpu_memory_utilization}

Prompt Modes (official HunyuanOCR prompts):
  parse-document   - Full document parsing to markdown (default)
  parse-formula    - LaTeX formula extraction
  parse-table      - HTML table extraction
  parse-chart      - Chart/flowchart parsing (Mermaid/Markdown)
  spot             - Text detection with coordinates
  extract-key      - Extract specific key value (requires --key)
  extract-fields   - Extract multiple fields as JSON (requires --fields)
  extract-subtitles - Subtitle extraction
  translate        - Document translation (requires --target-language)

Examples:
  # Basic document OCR (default)
  uv run hunyuan-ocr.py my-docs analyzed-docs

  # Extract formulas as LaTeX
  uv run hunyuan-ocr.py math-papers formulas --prompt-mode parse-formula

  # Extract tables as HTML
  uv run hunyuan-ocr.py reports tables --prompt-mode parse-table

  # Text spotting with coordinates
  uv run hunyuan-ocr.py images spotted --prompt-mode spot

  # Extract specific key from forms
  uv run hunyuan-ocr.py invoices amounts --prompt-mode extract-key --key "Total"

  # Extract multiple fields as JSON
  uv run hunyuan-ocr.py forms data --prompt-mode extract-fields --fields "name,date,amount"

  # Translate Chinese documents to English
  uv run hunyuan-ocr.py cn-docs translated --prompt-mode translate --target-language English

  # Use Chinese prompts
  uv run hunyuan-ocr.py docs output --use-chinese-prompts

  # Random sampling for testing
  uv run hunyuan-ocr.py large-dataset test --max-samples 50 --shuffle
