Mitsua/vroid-diffusion-test-unconditional

Model Card for VRoid Diffusion Unconditional

This is a latent unconditional diffusion model to demonstrate how U-Net training affects the generated images.

• Pretrained Text Encoder (OpenCLIP) is removed, but an empty text encoder is included for compatibility with StableDiffusionPipeline.
• VAE is from Mitsua Diffusion One, Mitsua Open RAIL-M License, Training Data: Public Domain/CC0 + Licensed
• U-Net is trained from scratch using full version of VRoid Image Dataset Lite with some modifications.
  • The architecture of the U-Net model was modified to conform to unconditional image generation. Cross-attention blocks are replaced by self-attention blocks.
• VRoid is a trademark or registered trademark of Pixiv inc. in Japan and other regions.

Model variant

• VRoid Diffusion
  • This is conditional text-to-image generator using OpenCLIP.

Note

• This model works only on diffusers StableDiffusionPipeline. This model will not work on A1111 WebUI.

from diffusers import StableDiffusionPipeline
pipeline = StableDiffusionPipeline.from_pretrained("Mitsua/vroid-diffusion-test-unconditional")

Model Description
