Personalized text-to-image generation has emerged as a powerful and
sought-after tool, empowering users to create customized images based on their
specific concepts and prompts. However, existing approaches to personalization
encounter multiple challenges, including long tuning times, large storage
requirements, the necessity for multiple input images per identity, and
limitations in preserving identity and editability. To address these obstacles,
we present PhotoVerse, an innovative methodology that incorporates a
dual-branch conditioning mechanism in both text and image domains, providing
effective control over the image generation process. Furthermore, we introduce
facial identity loss as a novel component to enhance the preservation of
identity during training. Remarkably, our proposed PhotoVerse eliminates the
need for test time tuning and relies solely on a single facial photo of the
target identity, significantly reducing the resource cost associated with image
generation. After a single training phase, our approach enables generating
high-quality images within only a few seconds. Moreover, our method can produce
diverse images that encompass various scenes and styles. The extensive
evaluation demonstrates the superior performance of our approach, which
achieves the dual objectives of preserving identity and facilitating
editability. Project page: https://photoverse2d.github.io/
