[N] Google's 'Imagen' Text-To-Image Beats Dalle-2 With Unprecedented Photorealism and Deep Level of Language Understanding

Imagen is a text-to-image diffusion model that builds on the power of large transformer language models in understanding text and hinges on the strength of diffusion models in high-fidelity image generation. Our key discovery is that generic large language models, pretrained on text-only corpora, are surprisingly effective at encoding text for image synthesis: increasing the size of the language model in Imagen boosts both sample fidelity and image-text alignment much more than increasing the size of the image diffusion model. …
