If you patch 4 the latent, you end up with 8x at 16 channels, the same as most modern VAEs, without the need for deep compression. The DiT does the patching, like it already does, and the VAE stays small. The latent is trained to keep its norm in line with noise, so there is no scaling factor, no shift factor, and no latent…
What people said about primal_vae on X
Today I am releasing Primal VAE in 2 variants, 2x1 and 2x2 (compression)x(channels). It only has a 2x compression and 1-2 channels, but with patching, it matches the compression of the FLUX 1 & 2 VAEs and beats FLUX2 VAE on reconstruction. More in README. https://huggingface.co/ostris/primal_vae

First experiment with Primal VAE: Training MOSS Image to use the 2x1 with a spatial compression of 64x. These are the current results from an overnight run. With this compression, it generates natively at 4096x4096 for same compute of 1024x1024 on MOSS Image.
