CreatiLayout is an innovative layout-to-image generation technology that employs the Siamese Multimodal Diffusion Transformer to achieve high-quality, finely controlled image outputs. This technology can accurately render complex attributes such as color, texture, shape, quantity, and text, making it suitable for applications that demand precise layout and image generation. Its primary benefits include efficient layout-guided integration, powerful image generation capabilities, and support for large-scale datasets. CreatiLayout is jointly developed by Fudan University and ByteDance, aimed at promoting the application of image generation technology in the creative design field.
