The Ideogram V2 node allows you to generate more refined images using Ideogram’s second-generation AI model, with significant improvements in text rendering, image quality, and overall aesthetics.

Parameters

Required Parameters

ParameterTypeDefaultDescription
promptstring""Text prompt describing the content to generate
turbobooleanFalseWhether to use turbo mode (faster generation, possibly lower quality)

Optional Parameters

ParameterTypeDefaultDescription
aspect_ratiodropdown”1:1”Image aspect ratio, effective when resolution is set to “Auto”
resolutiondropdown”Auto”Output image resolution, if not set to “Auto”, it will override the aspect_ratio setting
magic_prompt_optiondropdown”AUTO”Determines whether to use MagicPrompt feature during generation, options are [“AUTO”, “ON”, “OFF”]
seedinteger0Random seed value, range 0-2147483647
style_typedropdown”NONE”Generation style type (V2 only), options are [“AUTO”, “GENERAL”, “REALISTIC”, “DESIGN”, “RENDER_3D”, “ANIME”]
negative_promptstring""Specifies elements you don’t want to appear in the image
num_imagesinteger1Number of images to generate, range 1-8

Output

OutputTypeDescription
