# 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.
