TencentHyNode - ComfyUI Built-in Node Documentation - ComfyUI

This node generates text responses with Tencent’s Hy4 model. It sends a text prompt, plus optionally one or more images as context, and returns the model’s answer as text.

Inputs

Parameter	Description	Data Type	Required	Range
`model`	The model used to generate the answer. Selecting it reveals its inputs below. Default: `"Hy4"`.	DYNAMIC_COMBO	Yes	`"Hy4"`

Hy4 Inputs

These inputs appear when model is set to "Hy4".

Parameter	Description	Data Type	Required	Range
`prompt`	The message to send to the model. Must not be empty. Default: "" (empty string).	STRING	Yes	At least 1 character
`images`	Up to 20 images. Each image in a batch counts. Default: no images.	AUTOGROW	No	0 to 20 images
`seed`	Seed controls whether the node should re-run; results are non-deterministic regardless of seed. Default: 42.	INT	Yes	0 to 2147483647
`system_prompt`	Foundational instructions that dictate the model’s behavior. Default: "" (empty string).	STRING	No	-
`reasoning`	The model thinks before answering. Answers take longer and use more tokens, and very hard tasks can time out. Default: False.	BOOLEAN	Yes	true false
`temperature`	Controls randomness. Results still vary at 0. Default: 1.0.	FLOAT	Yes	0.0 to 1.4 (step: 0.01)
`max_tokens`	Maximum number of tokens to generate, including reasoning tokens when `reasoning` is on. Very long answers can time out. Default: 32000.	INT	Yes	1 to 64000

Constraints:

At most 20 images are accepted per request, counting each image of a batch.
Tencent’s content filter can block a request, which raises an error.
If max_tokens runs out before the answer finishes, the node raises an error: raise max_tokens or turn reasoning off.

Outputs

Output Name	Description	Data Type
`STRING`	The text answer from the Hy4 model.	STRING
