Disclaimer: this VAE is not intended to be a replacement for SD3's VAE since the latent spaces are entirely different.
A fully open source 16ch VAE reproduction for the SD3. Useful for people who are building their own image generation models and need an off-the-shelf VAE. Natively trained in fp16.
