Imagen uses a large pre-trained language model (T5-XXL) as a text encoder, and a cascade of diffusion models for 1024x1024 image generation. Imagen outperforms all existing techniques on MS-COCO benchmark by a considerable margin. Image
We introduce DrawBench, a comprehensive and challenging benchmark dataset to evaluate text-to-image model. Imagen outperforms all recent techniques on DrawBench. Image

A small thread on analysing text rendering capability of #imagen.

Starting with a simple example, Imagen is able to reliably render text without any need for rigorous cherrypicking. e.g. these are non-cherry picked examples for writing "Text-to-Image" on a storefront. Image
Imagen is also capable of writing text in a variety of
interesting settings. Here are some examples (1 sample picked out of 8 for each prompt). ImageImageImageImage
Some more examples of interesting settings... ImageImageImageImage
