Deep Dive into the Mechanism Differences Between Diffusion and Autoregressive Models

Developer kalomaze and other researchers recently provided a deep comparison of the fundamental mechanism differences between diffusion and discrete autoregressive (AR) models. They highlighted diffusion's advantages in handling i.i.d. training batches and suggested that AR models can maintain precision in higher-dimensional semantic modeling by parameterizing a larger joint probability space.
