Skywork/Unipic3-Consistency-Model

🌌 Unipic3-Consistency-Model

📖 Introduction

UniPic3-Consistency-Model is a few-step image editing and multi-image composition model based on Consistency Flow Matching (CM). The model learns a trajectory-consistent mapping from noisy latent states to clean images, enabling stable generation with strong structural consistency.
It is distilled from UniPic-3 to support fast inference (≤8 steps) while preserving composition correctness.The model is especially suitable for scenarios requiring geometric alignment and semantic coherence, such as multi-image composition and human–object interaction (HOI).
