VAE for creating pixel art with perfectly square pixels. This creates 4x4 pixels, see my older model for 8x8 pixels.
Since this is a VAE it will not affect the image generation in any way and will work with all models using the standard SDXL VAE, such as Pony, Illustrious, NoobXL, etc.. While this model does bias the image towards a pixel art style, you should use prompting and/or Lora's to push it to a specific pixel art style for best results.
If you want to use this VAE for Lora training, you should disable the caching of image latents since I have only trained the decoder, the encoder is stock.
