# Chain-of-Zoom Complete 4-bit Quantized Pipeline
|
18 |
+
|
19 |
+
## π Model Description
|
20 |
+
|
21 |
+
Complete 4-bit quantized Chain-of-Zoom pipeline with all models
|
22 |
+
|
23 |
+
This model is part of the **Chain-of-Zoom 4-bit Quantized Pipeline** - a memory-optimized version of the original Chain-of-Zoom super-resolution framework.
|
24 |
+
|
25 |
+
## π― Key Features
|
26 |
+
|
27 |
+
- **4-bit Quantization**: Uses BitsAndBytes NF4 quantization for 75% memory reduction
|
28 |
+
- **Maintained Quality**: Comparable performance to full precision models
|
29 |
+
- **Google Colab Compatible**: Runs on T4 GPU (16GB VRAM)
|
30 |
+
- **Memory Efficient**: Optimized for low-resource environments
|
31 |
+
|
32 |
+
## π Quantization Details
|
33 |
+
|
34 |
+
- **Method**: BitsAndBytes NF4 4-bit quantization
|
35 |
+
- **Compute dtype**: bfloat16/float16
|
36 |
+
- **Double quantization**: Enabled
|
37 |
+
- **Memory reduction**: ~75% compared to original
|
38 |
+
- **Original memory**: ~12GB β **Quantized**: ~3GB
|
39 |
+
|
40 |
+
