About Ideogram v4.5

Ideogram v4.5 is a text-to-image model focused on accurate typography, posters, logos, and graphic design.

It generates realistic and stylized images with low, medium, and high quality tiers and optional prompt expansion. Output is available at 1K (about 1024 to 1440 pixels on the long edge) or 2K (about 2048 to 2880 pixels) in square, portrait, landscape, 2:1 banner, and 16:10 aspect ratios, and Ideogram prices each image by quality tier only, so both resolutions cost the same.
