# π Chain-of-Zoom DIFFUSION (8-bit Optimized)
|
44 |
+
|
45 |
+
High-quality diffusion model optimized with 8-bit quantization for Chain-of-Zoom super-resolution. Core component for generating detailed super-resolved images.
|
46 |
+
|
47 |
+
## π― Model Overview
|
48 |
+
|
49 |
+
This is a **8-bit quantized** version of the DIFFUSION component for the Chain-of-Zoom super-resolution pipeline, specifically optimized for production deployment while maintaining exceptional quality.
|
50 |
+
|
51 |
+

|
53 |
+
- **Memory Usage**: 2.6GB (reduced from 5.2GB)
|
54 |
+
- **Memory Reduction**: 50% size reduction
|
55 |
+
- **Quality Preservation**: High quality maintained
|
56 |
+
- **Hardware Compatibility**: Optimized for Google Colab T4 GPU (16GB)
|

|
58 |
+
|
59 |
+
## π Chain-of-Zoom Pipeline Architecture
|
60 |
+
|
61 |
+
Chain-of-Zoom achieves extreme super-resolution (8x-32x) through intelligent autoregressive scaling:

|
67 |
+
```
|
68 |
+
|
69 |
+
### π§ 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 |
+
