ComfyUI-V-Prediction-Node

Node to set v-prediction sampling when using SDXL and other models that may not have the necessary metadata to identify it as a v-prediction model. This node is useful for quantized models since they lack the necessary metadata.

The basic workflow

The workflow is simple.

1. Add the "AddParam" node to your ComfyUI workflow.

2. Connect the "AddParam" node to the model loader node (e.g., the UNetLoader).

3. Select "epsilon" or "v_prediction" from the dropdown menu.

Installation

Use GIT:

1. Navigate to the custom_nodes folder inside the ComfyUI directory.

   cd ComfyUI/custom_nodes

2. Git-clone this repository

   git clone https://github.com/magekinnarus/ComfyUI-V-Prediction-Node.git

3. Restart ComfyUI after installing, and the node will be available for you to use.
