+This is a plugin/extension model for SDXL, not a fine-tuned version of stabilityai/stable-diffusion-xl-base-1.0.

 EcomID aims to generate customized images from a single reference ID image, ensuring strong semantic consistency while being controlled by keypoints.
 
 This repository provides the EcomID method and model, combining the strengths of [PuLID](https://github.com/ToTheBeginning/PuLID) and [InstantID](https://github.com/instantX-research/InstantID) for better background consistency, facial keypoint control, and realistic facial representation with improved similarity.
