Researchers have introduced ControlRef, a new framework designed to improve the efficiency and precision of layout-guided multi-instance image generation within Multi-Modal Diffusion Transformers (MM-DiTs). This system addresses limitations of previous methods, such as high computational costs and spatial-frequency compromises, by employing a Unified Instance-Layout Control (UILC) attention mask and a novel Anchored 4D-RoPE positional encoding. Experiments show ControlRef significantly reduces inference latency and memory overhead while maintaining state-of-the-art visual fidelity and localization accuracy. AI
