  # Mitsua Diffusion CC0 Model Card
  Mitsua Diffusion CC0 is a latent text-to-image diffusion model, whose U-Net is **trained from scratch using only public domain/CC0 or copyright images with permission for use**. 
  
  Text Encoder and VAE are borrowed from [Stable Diffusion v2.1 base](https://huggingface.co/stabilityai/stable-diffusion-2-1-base/). 
  
  This will be used as a base model for [**AI VTuber Elan Mitsua🖌️**](https://elanmitsua.com/en/)’s activity. 
  
  ❗❗ **Currently the model has super low visual quality and limited diversity** ❗❗
  
  Yes, the visual quality is not so good. Most of modern artistic concept is lost completely. However, since she is a growing AI in an ethical fashion, it would be good starting point for Mitsua-chan!
  
  You can join [her training on Twitter](https://twitter.com/elanmitsua)! Please support Mitsua-chan!🎉 
  
  Further training will be done in a fully opt-in basis. If you are interested in, [please click here to submit an opt-in application](https://forms.gle/Nk3M7UyqSgYAqdpA6).
  
  We are active on [a Discord server for opt-in participants only](https://discord.com/invite/7VTGRweTUg). Communication is currently in Japanese.
