Qwen3 VL OCR Script (MLX)

Purpose

Batch caption every image in an input directory using a local MLX vision-language model (Qwen3-VL-30B). Auto-downloads model weights. Fully offline OCR and image understanding.

Architecture

Single script (src/run_ocr.py):

1. Scans input directory for images
2. Auto-downloads Qwen3-VL-30B weights via huggingface-hub
3. Loads MLX model
4. Generates captions per image
5. Writes individual JSON files + combined captions.json

Output Format

• Individual JSON files per image with caption metadata
• Combined captions.json for batch analysis

Key Technologies

• Vision-Language Model: Qwen3-VL-30B via mlx-vlm
• Image Processing: OpenCV, Pillow, torchvision
• MLX Framework: Apple Silicon optimized

Dependencies

mlx, mlx-lm, Pillow, huggingface-hub, mlx-vlm, torch, torchvision, opencv-python, numpy
