Qwen-Image-Edit Face Generation Image Model

Model Introduction

This model is based on the Qwen-Image-Edit face-controlled image generation model. Given a cropped facial image as input, it generates full portrait images of the same person.

Result Demonstration

Face	Generated Image 1	Generated Image 2	Generated Image 3	Generated Image 4
