Nvidia has released an 8 billion parameter text-to-image diffusion model called NL-Diffusion-Image. This model utilizes a novel approach by encoding images into discrete tokens and employing a masked diffusion process, similar to diffusion LLMs. It builds upon Nvidia's Nemotron-Labs-Diffusion model and incorporates a token-editing mechanism for revising generated tokens and a Grouped Cross-Entropy objective for efficient training with large vocabularies.
