+ # πŸ” Chain-of-Zoom LORA (4-bit Optimized)
44
+
45
+ Specialized LoRA adapters with 4-bit quantization designed for Chain-of-Zoom pipeline fine-tuning and cross-component optimization.
46
+
47
+ ## 🎯 Model Overview
48
+
49
+ This is a **4-bit quantized** version of the LORA component for the Chain-of-Zoom super-resolution pipeline, specifically optimized for production deployment while maintaining exceptional quality.
50
+
51
+ ### ⚑ Key Features
52
+ - **Quantization**: 4-bit precision for optimal memory/quality balance
53
+ - **Memory Usage**: 25MB (reduced from 100MB)
54
+ - **Memory Reduction**: 75% size reduction
55
+ - **Quality Preservation**: Good quality maintained
56
+ - **Hardware Compatibility**: Optimized for Google Colab T4 GPU (16GB)
57
+ - **Framework**: PEFT compatible
58
+
59
+ ## πŸ“Š Chain-of-Zoom Pipeline Architecture
60
+
61
+ Chain-of-Zoom achieves extreme super-resolution (8x-32x) through intelligent autoregressive scaling:
62
+
63
+ ```
64
+ Input Image β†’ VLM Analysis β†’ Enhanced Prompts β†’ Diffusion SR β†’ Output Image
65
+ ↑ ↓ ↓ ↓ ↑
66
+ └─── RAM Tags ←─── LoRA Adapt ←─── Scale Chain ←─── Iterate
67
+ ```
68
+
69
+ ### πŸ”§ Component Roles:
70
+ 1. **VLM (8-bit)**: Context-aware prompt generation
71
+ 2. **Diffusion (8-bit)**: High-quality super-resolution
72
+ 3. **RAM (4-bit)**: Image analysis and tagging
73
+ 4. **LoRA (4-bit)**: Cross-component optimization
74
+
75
+ ## πŸš€ Quick Start
76
+
77
+ ```python
78
+ # Install requirements
79
+ pip install transformers diffusers torch accelerate bitsandbytes
80
+
81
+ # Load LORA model
82
+ from transformers import AutoModel, BitsAndBytesConfig
83
+ import torch
84
+
85
+ # Configure quantization
86
+ quantization_config = BitsAndBytesConfig(
87
+ load_in_4bit=True,
88
+ bnb_4bit_quant_type="nf4"
89
+ )
90
+
91
+ # Load quantized model
92
+ model = AutoModel.from_pretrained(
93
+ "humbleakh/lora-adapters-4bit-chain-of-zoom",
94
+ quantization_config=quantization_config,
95
+ device_map="auto",
96
+ torch_dtype=torch.bfloat16
97
+ )
98
+ ```

+ ## πŸ’» Integration Example
122
+
123
+ ```python
124
+ # LoRA Integration
125
+ from chain_of_zoom import ChainOfZoom8BitOptimal
126
+
127
+ # Initialize pipeline
128
+ pipeline = ChainOfZoom8BitOptimal()
129
+
130
+ # Load your image
131
+ from PIL import Image
132
+ image = Image.open("low_res_image.jpg")
133
+
134
+ # Run super-resolution
135
+ results = pipeline.chain_of_zoom(image, target_scale=8)
136
+ final_image = results[-1]['image']
137
+ final_image.save("super_resolved_8x.jpg")
138
+ ```
139
+
