Since the encoding is performed by a Variational Autoencoder, the VAE encoder must output some mean and log variance that we can use to sample a latent vector of shape (latent_dim,). But then how does Stable Diffusion use a vector of shape 64x64x3?

Why Latent Spacedoes the latent space in Stable Diffusion hashave a shape of 64x64x3?

I am wondering why the dimensionality of Latent Space in Stable Diffusion is 64x64x3. Since the encoding is performed by Variational Autoencoder ita Variational Autoencoder, the VAE encoder must output some mean and log variance that we can use to sample a latent vectorlatent vector of shape (latent_dim, ).
