# OrbitQuant SDXL UNet Exports
|
| 16 |
+
|
| 17 |
+
Custom UNet-only OrbitQuant exports for CreaPrompt Lightning Hyper-SDXL.
|
| 18 |
+
|
| 19 |
+
These files are **not normal SDXL checkpoints**. They contain only `model.diffusion_model.*`
|
| 20 |
+
UNet tensors plus `__orbitquant__` metadata/codebooks/rotations. They require a custom
|
| 21 |
+
runtime that supports packed OrbitQuant weights and A4 activation quantization.
|
| 22 |
+
|
| 23 |
+
Expected files:
|
| 24 |
+
|
| 25 |
+
- `creaprompt_UNet_OrbitQuant_W4A4_projio.safetensors`
|
| 26 |
+
- `creaprompt_UNet_OrbitQuant_W3A4_projio.safetensors`
|
| 27 |
+
- `creaprompt_UNet_OrbitQuant_W2A4_projio.safetensors`
|
| 28 |
+
|
| 29 |
+
The VAE and CLIP/text encoders are not included.
