Researchers have introduced Delta-K, a novel inference framework designed to enhance the generation of complex multi-instance scenes in diffusion models. This plug-and-play method operates by augmenting the cross-attention Key space, specifically targeting and injecting the semantic signature of missing concepts. By utilizing a lightweight Vision-Language Model, Delta-K isolates a differential key ($\Delta K$) that is then integrated early in the generation process, grounding noise into stable structures without altering existing concepts. Experiments show Delta-K improves compositional alignment across various diffusion model architectures like DiT and U-Net without needing spatial masks or additional training. AI
