Ideogram v4.5 - Oxen.ai

Try Ideogram v4.5 in the Workbench

Run this model interactively, tune parameters, and compare outputs.

Model ID: 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.

Request parameters

Required parameters

Field	Type	Default	Description
`prompt`	`string`	—	Describe the image to generate, including any text and its placement.

Optional parameters

Field	Type	Default	Description
`aspect_ratio`	`string`	`"1:1"`	Aspect Ratio One of: 1:1, 16:9, 9:16, 4:3, 3:4, 3:2, 2:3, 5:4, 4:5, 16:10, 10:16, 2:1, 1:2.
`resolution`	`string`	`"1K"`	Resolution One of: 1K, 2K.
`image_size`	`object`	—	Pixel dimensions sent to fal, looked up from aspect_ratio and resolution in the size table below.
`quality`	`string`	`"medium"`	Image quality tier. Low costs $0.03, medium$ 0.06, and high $0.22 per image, independent of image size. One of: low, medium, high.
