ByteDanceImageNode - ComfyUI Built-in Node Documentation

The ByteDance Image node generates images using ByteDance models through an API based on text prompts. It allows you to select a model, specify image dimensions, and control various generation parameters like seed and guidance scale. The node connects to ByteDance’s image generation service and returns the created image.

Inputs

Parameter	Description	Data Type	Required	Range
`model`	The ByteDance model to use for image generation. Currently only one model option is available.	STRING	Yes	`"seedream-3-0-t2i-250415"`
`prompt`	The text prompt used to generate the image. Must be at least 1 character long after stripping whitespace.	STRING	Yes	-
`size_preset`	Pick a recommended size. Select Custom to use the width and height below. Available presets are defined by the `RECOMMENDED_PRESETS` list.	STRING	Yes	See description
`width`	Custom width for the image. This value is only used when `size_preset` is set to `Custom`. Default: 1024.	INT	Yes	512 to 2048 (step 64)
`height`	Custom height for the image. This value is only used when `size_preset` is set to `Custom`. Default: 1024.	INT	Yes	512 to 2048 (step 64)
`seed`	Seed to use for generation. Default: 0.	INT	No	0 to 2147483647 (step 1)
`guidance_scale`	Higher value makes the image follow the prompt more closely. Default: 2.5.	FLOAT	No	1.0 to 10.0 (step 0.01)
`watermark`	Whether to add an “AI generated” watermark to the image. Default: False. This is an advanced parameter.	BOOLEAN	No	True / False

Note on size parameters: The width and height parameters are only used when size_preset is set to Custom. If a preset size is selected, the preset’s dimensions override the custom width and height values. Both width and height must be between 512 and 2048 pixels when using custom dimensions.

Outputs
