GeminiNodeV2 - ComfyUI Built-in Node Documentation

Generate text responses with Google’s Gemini models. Provide a text prompt and, optionally, one or more images, audio clips, videos, or files as multimodal context.

Inputs

Parameter	Description	Data Type	Required	Range
`prompt`	Text input to the model. Include detailed instructions, questions, or context.	STRING	Yes
`model`	The Gemini model used to generate the response.	COMBO	Yes	`"Gemini 3.1 Pro"` `"Gemini 3.1 Flash-Lite"`
`seed`	Seed for sampling. Set to 0 for a random seed. Deterministic output isn’t guaranteed. (default: 42)	INT	Yes	0 to 2147483647
`system_prompt`	Foundational instructions that dictate the model’s behavior. (default: "")	STRING	No

Note: When providing images, audio, or video as multimodal context, the node uploads media as URLs for the first 10 inputs. Any additional media is sent inline as base64 data, with a maximum inline payload of 18 MB. If the inline payload exceeds this limit, an error is raised.

Outputs

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