LUA Latent Upscale Adapter Open-Sourced, Speeds Up Diffusion Nearly 3x

LUA, an ECCV 2026 latent upscale adapter for diffusion models, performs x2/x4 super-resolution in latent space before VAE decoding, skipping pixel upsampling and speeding up generation nearly 3x. Its official implementation is now open-sourced, supporting SDXL, SD3 and FLUX.
