Sage_ModelShifts
Model Shifts
Configures model shift parameters and FreeU v2 settings for advanced model modifications.
Inputs
Required
- shift_type (STRING): The type of shift to apply to the model - "None", "x1", or "x1000" (x1 for most models, x1000 for Auraflow and Lumina2)
- shift (FLOAT): The shift value to apply (default: 3.0, range: 0.0-100.0)
- freeu_v2 (BOOLEAN): Whether to enable FreeU v2 (default: False)
- b1 (FLOAT): FreeU v2 backbone factor 1 (default: 1.3, range: 0.0-10.0)
- b2 (FLOAT): FreeU v2 backbone factor 2 (default: 1.4, range: 0.0-10.0)
- s1 (FLOAT): FreeU v2 skip factor 1 (default: 0.9, range: 0.0-10.0)
- s2 (FLOAT): FreeU v2 skip factor 2 (default: 0.2, range: 0.0-10.0)
Outputs
- model_shifts (MODEL_SHIFTS): Configuration object containing all shift and FreeU settings
Usage
Use in workflows that require dynamic model parameter adjustment. Connect to LoRA Stack Loader or Model LoRA Stack Loader nodes.
Notes
- Model shifts adjust sampling parameters for different model architectures
- x1 shift type uses 1000.0 multiplier (for most models)
- x1000 shift type uses 1.0 multiplier (for Auraflow and Lumina2)
- FreeU v2 can improve generation quality with proper parameter tuning
- Settings are passed to model loader nodes for application
- "None" shift type disables model shifting
- Used by the model loader node for advanced model modifications
- Part of the "Sage Utils/model" category despite being in lora.py
