# GeminiNodeV2 - ComfyUI Built-in Node Documentation
> Generate text responses with Google's Gemini models.
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
### Common Inputs
| Parameter | Description | Data Type | Required | Range |
| --------------- | ------------------------------------------------------------------------------------------------------------------------------------------------ | -------------- | -------- | ----------------------------------------------------------------------------------------------------- |
| `model` | The Gemini model used to generate the response. | DYNAMIC\_COMBO | Yes | `"Gemini 3.7 Flash"`
`"Gemini 3.5 Flash"`
`"Gemini 3.1 Pro"`
`"Gemini 3.1 Flash-Lite"` |
| `prompt` | Text input to the model. Include detailed instructions, questions, or context. Must contain at least one non-whitespace character. (default: "") | STRING | Yes | |
| `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 | |
### Gemini 3.7 Flash Inputs
These inputs appear when `model` is set to `"Gemini 3.7 Flash"`.
| Parameter | Description | Data Type | Required | Range |
| ------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | ------------------------------------- |
| `thinking_level` | How hard the model reasons internally before answering. HIGH improves quality on difficult tasks but costs more (thinking) tokens and is slower. (default: "MEDIUM") | COMBO | Yes | `"LOW"`
`"MEDIUM"`
`"HIGH"` |
| `temperature` | Controls randomness. Lower is more focused/deterministic, higher is more creative. (default: 1.0) | FLOAT | Yes | 0.0 to 2.0 |
| `top_p` | Nucleus sampling: sample from the smallest token set whose cumulative probability reaches top\_p. (default: 0.95) | FLOAT | Yes | 0.0 to 1.0 |
| `max_output_tokens` | Maximum tokens to generate, including the model's internal thinking. With thinking\_level HIGH, a low value can leave no room for the answer; raise this if responses come back empty or truncated. The model stops early when finished, so a higher cap costs nothing extra for short replies. (default: 32768) | INT | Yes | 16 to 65536 |
### Gemini 3.5 Flash Inputs
These inputs appear when `model` is set to `"Gemini 3.5 Flash"`.
| Parameter | Description | Data Type | Required | Range |
| ------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | ------------------------------------------------------ |
| `thinking_level` | How hard the model reasons internally before answering. HIGH improves quality on difficult tasks but costs more (thinking) tokens and is slower. (default: "MEDIUM") | COMBO | Yes | `"MINIMAL"`
`"LOW"`
`"MEDIUM"`
`"HIGH"` |
| `temperature` | Controls randomness. Lower is more focused/deterministic, higher is more creative. (default: 1.0) | FLOAT | Yes | 0.0 to 2.0 |
| `top_p` | Nucleus sampling: sample from the smallest token set whose cumulative probability reaches top\_p. (default: 0.95) | FLOAT | Yes | 0.0 to 1.0 |
| `max_output_tokens` | Maximum tokens to generate, including the model's internal thinking. With thinking\_level HIGH, a low value can leave no room for the answer; raise this if responses come back empty or truncated. The model stops early when finished, so a higher cap costs nothing extra for short replies. (default: 32768) | INT | Yes | 16 to 65536 |
### Gemini 3.1 Pro Inputs
These inputs appear when `model` is set to `"Gemini 3.1 Pro"`.
| Parameter | Description | Data Type | Required | Range |
| ------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | --------------------- |
| `thinking_level` | How hard the model reasons internally before answering. HIGH improves quality on difficult tasks but costs more (thinking) tokens and is slower. (default: "HIGH") | COMBO | Yes | `"LOW"`
`"HIGH"` |
| `temperature` | Controls randomness. Lower is more focused/deterministic, higher is more creative. (default: 1.0) | FLOAT | Yes | 0.0 to 2.0 |

| `max_output_tokens` | Maximum tokens to generate, including the model's internal thinking. With thinking\_level HIGH, a low value can leave no room for the answer; raise this if responses come back empty or truncated. The model stops early when finished, so a higher cap costs nothing extra for short replies. (default: 32768) | INT | Yes | 16 to 65536 |
### Gemini 3.1 Flash-Lite Inputs
These inputs appear when `model` is set to `"Gemini 3.1 Flash-Lite"`.
| Parameter | Description | Data Type | Required | Range |
| ------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | --------------------- |
| `thinking_level` | How hard the model reasons internally before answering. HIGH improves quality on difficult tasks but costs more (thinking) tokens and is slower. (default: "LOW") | COMBO | Yes | `"LOW"`
`"HIGH"` |
| `temperature` | Controls randomness. Lower is more focused/deterministic, higher is more creative. (default: 1.0) | FLOAT | Yes | 0.0 to 2.0 |
| `top_p` | Nucleus sampling: sample from the smallest token set whose cumulative probability reaches top\_p. (default: 0.95) | FLOAT | Yes | 0.0 to 1.0 |
| `max_output_tokens` | Maximum tokens to generate, including the model's internal thinking. With thinking\_level HIGH, a low value can leave no room for the answer; raise this if responses come back empty or truncated. The model stops early when finished, so a higher cap costs nothing extra for short replies. (default: 32768) | INT | Yes | 16 to 65536 |
### Media and File Inputs
The following inputs are shared by all four models and appear alongside the model-specific inputs.
| Parameter | Description | Data Type | Required | Range |
| --------- | ------------------------------------------------------------------------------------------------------------------------------------- | -------------------- | -------- | -------------- |
| `images` | Growable slot: connect 1 to 16 images (`image_1` ... `image_16`). Optional image(s) to use as context for the model. Up to 16 images. | IMAGE | No | 0 to 16 images |
| `audio` | Growable slot: connect one audio clip (`audio_1`). Optional audio clip to use as context for the model. | AUDIO | No | 0 to 1 clip |
| `video` | Growable slot: connect one video clip (`video_1`). Optional video clip to use as context for the model. | VIDEO | No | 0 to 1 clip |
| `files` | Optional file(s) to use as context for the model. Accepts inputs from the Gemini Input Files node. | GEMINI\_INPUT\_FILES | No | |
**Note:** When media (images, audio, or video) is attached, the node uploads the first 10 media items to ComfyAPI storage and passes them as URLs; this URL budget is shared across all media types and is consumed in order (video first, then audio, then images). Any remaining media is encoded inline as base64 data, with a maximum combined inline payload of 18 MB. If the inline payload would exceed 18 MB, the node raises an error. The `prompt` parameter must contain at least one non-whitespace character. Setting `seed` to 0 requests a random seed.
## Outputs
| Output Name | Description | Data Type |
| ----------- | ----------------------------------------------------------------------------------------------------------------------------------------------- | --------- |
| `output` | The generated text response from the Gemini model. If the model produces no text, the string "Empty response from Gemini model..." is returned. | STRING |
