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.
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.
