Usage
Advanced GGUF pipeline loader with full control over quantization and loading parameters. Use dequant_dtype
and patch_dtype to balance precision and VRAM usage during dequantization. Supports up to 4 simultaneous
LoRAs applied at load time. Enable "Flux Shift" to apply resolution-aware sampling shift — adjust
base_sampling_shift, max_sampling_shift, and the reference resolution to tune the shift curve.
Use advanced device options to offload components as needed.
