[ICLR 2025] Deep Compression Autoencoder for Efficient High-Resolution Diffusion Models [paper] [readme] [poster]

Deep Compression Autoencoder (DC-AE) is a new family of high-spatial compression autoencoders with a spatial compression ratio of up to 128 while maintaining reconstruction quality. It accelerates all latent diffusion models regardless of the diffusion model architecture.

Demo

Figure 1: We address the reconstruction accuracy drop of high spatial-compression autoencoders.

Figure 2: DC-AE speeds up latent diffusion models.

Figure 3: DC-AE enables efficient text-to-image generation on the laptop: SANA.
