# 🔍 Chain-of-Zoom VLM (8-bit Optimized)

Qwen2.5-VL-3B optimized with 8-bit quantization for Chain-of-Zoom super-resolution pipeline. Provides high-quality prompt generation for context-aware super-resolution.

## 🎯 Model Overview

This is a **8-bit quantized** version of the VLM component for the Chain-of-Zoom super-resolution pipeline, specifically optimized for production deployment while maintaining exceptional quality.

### ⚡ Key Features
- **Quantization**: 8-bit precision for optimal memory/quality balance
- **Memory Usage**: 3.0GB (reduced from 6.0GB)
- **Memory Reduction**: 50% size reduction
- **Quality Preservation**: High quality maintained
- **Hardware Compatibility**: Optimized for Google Colab T4 GPU (16GB)
- **Framework**: Transformers compatible

## 📊 Chain-of-Zoom Pipeline Architecture

Chain-of-Zoom achieves extreme super-resolution (8x-32x) through intelligent autoregressive scaling:

```
Input Image → VLM Analysis → Enhanced Prompts → Diffusion SR → Output Image
     ↑             ↓              ↓               ↓           ↑
     └─── RAM Tags ←─── LoRA Adapt ←─── Scale Chain ←─── Iterate
```

### 🔧 Component Roles:
1. **VLM (8-bit)**: Context-aware prompt generation
2. **Diffusion (8-bit)**: High-quality super-resolution
3. **RAM (4-bit)**: Image analysis and tagging
4. **LoRA (4-bit)**: Cross-component optimization

## 🚀 Quick Start

```python
# Install requirements
pip install transformers diffusers torch accelerate bitsandbytes

# Load VLM model
from transformers import AutoModel, BitsAndBytesConfig
import torch

# Configure quantization
quantization_config = BitsAndBytesConfig(
    load_in_8bit=True,
    llm_int8_threshold=6.0
)

# Load quantized model
model = AutoModel.from_pretrained(
    "humbleakh/qwen2.5-vl-3b-8bit-chain-of-zoom",
    quantization_config=quantization_config,
    device_map="auto",
    torch_dtype=torch.bfloat16
)
```

## 📈 Performance Metrics

| Metric | Original | 8-bit Quantized | Improvement |

from chain_of_zoom import ChainOfZoom8BitOptimal

# Initialize pipeline
pipeline = ChainOfZoom8BitOptimal()

# Load your image
from PIL import Image
image = Image.open("low_res_image.jpg")

# Run super-resolution
results = pipeline.chain_of_zoom(image, target_scale=8)
final_image = results[-1]['image']
final_image.save("super_resolved_8x.jpg")
```

## 🎯 Applications

- **Photo Enhancement**: Restore old or low-quality photos
