+The Abstract of the paper:
+>Diffusion models are the _de-facto_ approach for generating high-quality images and videos but learning high-dimensional models remains a formidable task due to computational and optimization challenges. Existing methods often resort to training cascaded models in pixel space, or using a downsampled latent space of a separately trained auto-encoder. In this paper, we introduce Matryoshka Diffusion (MDM), **a novel framework for high-resolution image and video synthesis**. We propose a diffusion process that denoises inputs at multiple resolutions jointly and uses a **NestedUNet** architecture where features and parameters for small scale inputs are nested within those of the large scales. In addition, MDM enables a progressive training schedule from lower to higher resolutions which leads to significant improvements in optimization for high-resolution generation. We demonstrate the effectiveness of our approach on various benchmarks, including class-conditioned image generation, high-resolution text-to-image, and text-to-video applications. Remarkably, we can train a **_single pixel-space model_ at resolutions of up to 1024 × 1024 pixels**, demonstrating strong zero shot generalization using the **CC12M dataset, which contains only 12 million images**. Code and pre-trained checkpoints are released at https://github.com/apple/ml-mdm.
