               We introduce a new Autoencoder (AE) that aggressively increases the scaling factor to 32.
               Compared with AE-F8, our AE-F32 outputs 16× fewer latent tokens, which is crucial for efficient training
               and generating ultra-high-resolution images, such as 4K resolution.<br>
