| # OrbitQuant SDXL UNet Exports |
|
|
| Custom UNet-only OrbitQuant exports for CreaPrompt Lightning Hyper-SDXL. |
|
|
| These files are not normal SDXL checkpoints. They contain only `model.diffusion_model.*` |
| UNet tensors plus `__orbitquant__` metadata/codebooks/rotations. They require a custom |
| runtime that supports packed OrbitQuant weights and A4 activation quantization. |
