Ideogram V1 - ComfyUI Native Node Documentation

Node for creating precise text rendering images using Ideogram API

The Ideogram V1 node allows you to generate images with high-quality text rendering capabilities using Ideogram’s text-to-image API.

Parameter Description

Required Parameters

Parameter	Type	Default	Description
prompt	string	""	Text prompt describing the content to generate
turbo	boolean	False	Whether to use turbo mode (faster but possibly lower quality)
aspect_ratio	select	”1:1”	Image aspect ratio
magic_prompt_option	select	”AUTO”	Determines whether to use MagicPrompt in generation, options: AUTO, ON, OFF
seed	integer	0	Random seed value (0-2147483647)
negative_prompt	string	""	Specifies elements you don’t want in the image
num_images	integer	1	Number of images to generate (1-8)

Output

Output	Type	Description
IMAGE	image	Generated image result
