Diffusion Cocktail: Fused Generation from Diffusion Models
Haoming Liu Yuanhe Guo Shengjie Wang Hongyi Wen
Diffusion models excel at generating high-quality images and are easy to
extend, making them extremely popular among active users who have created an
extensive collection of diffusion models with various styles by fine-tuning
base models such as Stable Diffusion. Recent work has focused on uncovering
semantic and visual information encoded in various components of a diffusion
model, enabling better generation quality and more fine-grained control.
However, those methods target improving a single model and overlook the vastly
available collection of fine-tuned diffusion models. In this work, we study the
combinations of diffusion models. We propose Diffusion Cocktail (Ditail), a
training-free method that can accurately transfer content information between
two diffusion models. This allows us to perform diverse generations using a set
of diffusion models, resulting in novel images that are unlikely to be obtained
by a single model alone. We also explore utilizing Ditail for style transfer,
with the target style set by a diffusion model instead of an image. Ditail
offers a more detailed manipulation of the diffusion generation, thereby
enabling the vast community to integrate various styles and contents seamlessly
and generate any content of any style.
