sarcastictofu/UltraFlux VAE (Mirrored from Hugging Face Repo)
UltraFlux VAE is a high-performance Variational Autoencoder specifically engineered to solve the "softness" and memory bottlenecks associated with native 4K image generation in the Flux ecosystem. While standard Flux models typically utilize an F8 VAE that results in massive latent grids and slow processing times at high resolutions, UltraFlux adopts a more efficient F16 (16x downsampling) architecture. This significantly reduces the computational load and increases throughput, but because aggressive compression often risks losing micro-details, the developers implemented a specialized non-adv
