📖 Introduction

<div align="center"> <img src="unipic3.png" alt="Model Teaser" width="720"> </div>

UniPic3-DMD-Model is a few-step image editing and multi-image composition model trained using Distribution Matching Distillation (DMD). The model directly matches the output distribution of a high-quality teacher model, enabling sharp, visually detailed generations in very few inference steps. It is designed to maximize perceptual quality and realism, closely imitating strong proprietary or large teacher models. This model is initialized from a consistency-trained checkpoint and further refined via distribution-level distillation.
