ByteDanceSeedNode - ComfyUI Built-in Node Documentation

Generate text responses using ByteDance’s Seed 2.0 models.

Generate text responses using ByteDance’s Seed 2.0 models. Provide a text prompt and optionally include images or videos for multimodal context.

Inputs

Common Inputs

Parameter	Description	Data Type	Required	Range
model	The Seed model used to generate the response.	DYNAMIC_COMBO	Yes	"Seed 2.0 Pro" "Seed 2.0 Lite" "Seed 2.0 Mini"
prompt	Text input to the model. (default: "")	STRING	Yes	N/A
seed	Seed controls whether the node should re-run; results are non-deterministic regardless of seed. (default: 0)	INT	Yes	0 to 2147483647
system_prompt	Foundational instructions that dictate the model’s behavior. (default: "")	STRING	No	N/A

Model Inputs (Shared by Seed 2.0 Pro, Seed 2.0 Lite, and Seed 2.0 Mini)

All three Seed models expose the same sub-parameters when selected.

Parameter	Description	Data Type	Required	Range
temperature	Controls randomness. 0.0 is deterministic, higher values are more random. (default: 1.0)	FLOAT	Yes	0.0 to 2.0 (step: 0.01)

Reference Inputs

Parameter	Description	Data Type	Required	Range
images	Optional image(s) to use as context for the model. Up to 20 images. Growable slot: connect 1..20 items, e.g. image_1 through image_20.	IMAGE	No	0 to 20 images
videos	Optional video(s) to use as context for the model. Up to 4 videos. Growable slot: connect 1..4 items, e.g. video_1 through video_4.	VIDEO	No	0 to 4 videos

Note: The model parameter is a dynamic combo that exposes the reference and temperature sub-parameters when a model is selected. You can connect image and video inputs to this parameter to provide multimodal context. A maximum of 20 images and 4 videos are supported per request, and prompt is required and must contain at least one non-whitespace character.

Outputs

Output Name	Description	Data Type
output	The generated text response from the Seed model.	STRING
