# 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.

Expected files:

- `creaprompt_UNet_OrbitQuant_W4A4_projio.safetensors`
- `creaprompt_UNet_OrbitQuant_W3A4_projio.safetensors`
- `creaprompt_UNet_OrbitQuant_W2A4_projio.safetensors`

The VAE and CLIP/text encoders are not included.
