# Model Card for VRoid Diffusion Unconditional
<!-- Provide a quick summary of what the model is/does. -->
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](https://huggingface.co/Mitsua/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](https://huggingface.co/datasets/Mitsua/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](https://huggingface.co/Mitsua/vroid-diffusion-test)
- 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")
```
