--- tags: - Sampling --- # ModelSamplingStableCascade ## Documentation - Class name: `ModelSamplingStableCascade` - Category: `advanced/model` - Output node: `False` This node is designed to enhance the sampling process of models by applying a stable cascade patch. It clones the input model and integrates advanced sampling techniques, thereby potentially improving the model's performance or altering its behavior in a specified manner. ## Input types ### Required - **`model`** - The model to which the stable cascade sampling patch will be applied. This parameter is crucial as it determines the base model that will undergo modification. - Comfy dtype: `MODEL` - Python dtype: `comfy.model_base.BaseModel` - **`shift`** - A floating-point value that specifies the degree of shift to be applied during the sampling process. This parameter influences how the model's behavior is altered by the patch. - Comfy dtype: `FLOAT` - Python dtype: `float` ## Output types - **`model`** - Comfy dtype: `MODEL` - The modified model with the stable cascade sampling patch applied. This output reflects the enhanced or altered version of the input model. - Python dtype: `comfy.model_base.BaseModel` ## Usage tips - Infra type: `CPU` - Common nodes: unknown ## Source code ```python class ModelSamplingStableCascade: @classmethod def INPUT_TYPES(s): return {"required": { "model": ("MODEL",), "shift": ("FLOAT", {"default": 2.0, "min": 0.0, "max": 100.0, "step":0.01}), }} RETURN_TYPES = ("MODEL",) FUNCTION = "patch" CATEGORY = "advanced/model" def patch(self, model, shift): m = model.clone() sampling_base = comfy.model_sampling.StableCascadeSampling sampling_type = comfy.model_sampling.EPS class ModelSamplingAdvanced(sampling_base, sampling_type): pass model_sampling = ModelSamplingAdvanced(model.model.model_config) model_sampling.set_parameters(shift) m.add_object_patch("model_sampling", model_sampling) return (m, ) ```
