cant use these models without it, still working on the comfyUI node for loader to pipe into core ksampler

WIP for W2A4 block-level rollout recovery

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. examples/download (1).png
