The ComfyUI Plus repo is a fork of ComfyUI with the addition of custom nodes to provide enhanced image generation quality.
All workflows make use of the linked ComfyUI node layout but have custom hyperparameters as described under the Comfy Wrapper API page.

We make use of UltralyticsDetectorProvider and FaceDetailer from the ComfyUI impact pack to detect when faces are present in the image and to enhance details on the face as humans are very sensitive to irregularities in faces and this is somewhere many AI image models struggle.
