## 📖 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.
