# Google Generative AI

> Configure Google Gemini models in AI Gateway for language generation, embeddings, and multi-modal AI capabilities.

## Overview

Google Generative AI provides access to Google's powerful Gemini family of models through the Google AI Studio API. These models offer advanced language understanding, multi-modal capabilities, and high-quality text generation.

## Configuration

To use Google Generative AI, configure it in the Plugin settings page under the `AI Gateway` section:

| Field        | Description                                    | Example                                           |
| ------------ | ---------------------------------------------- | ------------------------------------------------- |
| **API Key**  | Your Google API key                            | `your-google-api-key`                             |
| **Base URL** | Optional, to point at a gateway                | `https://ai-gateway.example.com/google`           |
| **Headers**  | Optional, e.g. for authentication with gateway | Key: `X-Custom-Header`<br />Value: `custom-value` |

Then set the default language model (or configure it per-plugin):

```
Language Model: google|gemini-2.5-flash
```
