Photorealistic Text-to-Image Diffusion Models with Deep Language Understanding (Imagen)

Chitwan Saharia, William Chan, Saurabh Saxena, Mohammad Norouzi

Showed that conditioning an image-diffusion model on a large frozen text encoder yields high-fidelity, well-aligned text-to-image generation, highlighting the text encoder as the key lever.

Editorial record

Plain-language summary

Imagen pairs a frozen T5-XXL language-model text encoder with a cascade of diffusion models and finds that scaling the text encoder improves image-text alignment more than scaling the image model. It reached strong photorealism and prompt fidelity on standard evaluations. It clarified the role of language understanding in text-to-image systems.
