Embedding Prediction Helps Image Generation

Sihan Xu, Ji Xie, Zilin Wang et al.1 min readarXivOct 1, 2026

Key Takeaway for Students

In diffusion transformers, a class label or a text prompt is embedded once, and the same condition is reused at every denoising step. We ask whether predicted embeddings can serve as this condition instead. Next-Embedding Predictive Autoregression (NEPA) trains a AI architecture to predict the next continuous embedding in a sequence. In generation, the clean image follows the n

Why it matters

This paper introduces a novel conditioning mechanism for diffusion transformers, adapting the conditioning signal dynamically during generation. This could lead to more precise and higher-quality image generation, especially in complex scenarios, by allowing the model to react to the evolving noisy image state. For ML engineers, understanding this adaptive conditioning opens doors to developing more sophisticated generative models and optimizing their performance.
