New NEPA method enhances image generation in diffusion transformers

Researchers have developed a new method called Next-Embedding Predictive Autoregression (NEPA) for image generation using diffusion transformers. This approach trains a transformer to predict continuous embeddings sequentially, allowing the conditioning signal to adapt dynamically during the denoising process. Experiments on ImageNet demonstrated that NEPA-DiT-XL, a model incorporating this technique, achieved a competitive FID score with significantly reduced training compute compared to previous methods.
