Furthermore, Transformers revolutionize language processing through mechanisms such as attention, which weigh the significance of various words in a prompt. This approach is vital for context retention and generating images that are coherent and contextually accurate.
The image generation prowess of Imagen 4 is vested in its use of cascaded diffusion models, integral in producing high-fidelity photos. This pipeline begins with a base diffusion model that generates a low-resolution image (e.g., 64x64 pixels) conditioned on the text embedding from the Transformer. This initial image captures the core composition and content of the prompt.
Following this, the model employs a series of super-resolution diffusion models that intelligently upsample the image, first to 256x256 pixels and finally to a high-definition 1024x1024 image or even larger. Each stage of this diffusion process allows for precise detail enhancement, securing a realistic and intricate final image. This advancement not only positions Imagen 4 as a frontrunner in rendering photorealistic imagery from text but also establishes new industry standards, as demonstrated when the original Imagen achieved a state-of-the-art Fréchet Inception Distance (FID) score of 7.27 on the challenging COCO dataset.
