<Icon name="Blocks" aria-hidden="true" /> [**Bundles**](/components-bundle-components) contain custom components that support specific third-party integrations with Langflow.

This page describes the components that are available in the **Google** bundle.

## BigQuery

Langflow integrates with [Google BigQuery](https://cloud.google.com/bigquery) through the **BigQuery** component in the [**Google** bundle](/bundles-google), allowing you to execute SQL queries and retrieve data from your BigQuery datasets.

### Use the BigQuery component in a flow

To use the **BigQuery** component in a flow, you need the following:

* A [Google Cloud project](https://developers.google.com/workspace/guides/create-project) with the BigQuery API enabled
* A [service account](https://developers.google.com/workspace/guides/create-credentials#service-account) with the **BigQuery Job User** role
* A [BigQuery dataset and table](https://cloud.google.com/bigquery/docs/datasets-intro)
* A [running Langflow server](/get-started-installation)

#### Create a service account with BigQuery access

1. Select and enable your Google Cloud project.
For more information, see [Create a Google Cloud project](https://developers.google.com/workspace/guides/create-project).
2. Create a service account in your Google Cloud project.
For more information, see [Create a service account](https://developers.google.com/workspace/guides/create-credentials#service-account).
3. Assign the **BigQuery Job User** role to your new account.
This role allows Langflow to access BigQuery resources with the service account.
You may also need to allow access to your BigQuery dataset.
For more information, see [BigQuery access control with IAM](https://cloud.google.com/bigquery/docs/access-control).
4. To generate a new JSON key for the service account, navigate to your service account.
5. Click **Add Key**, and then click **Create new key**.
6. Under **Key type**, select **JSON**, and then click **Create**.
A JSON private key file is downloaded to your machine.
Now that you have a service account and a JSON private key, you need to configure the credentials in the Langflow **BigQuery** component.

#### Configure credentials in the Langflow component

With your service account configured and your credentials JSON file created, follow these steps to authenticate the Langflow application.

1. Create a new flow in Langflow.
2. In <Icon name="Blocks" aria-hidden="true" /> **Bundles**, find the Google **BigQuery** component, and then add it to your flow.
3. In the **BigQuery** component's **Upload Service Account JSON** field, click **Select file**.
4. In the **My Files** pane, select **Click or drag files here**.
Your file browser opens.
5. In your file browser, select the service account JSON file, and then click **Open**.
6. In the **My Files** pane, select your service account JSON file, and then click **Select files**.
The **BigQuery** component can now query your datasets and tables using your service account JSON file.

#### Query a BigQuery dataset

With your component credentials configured, query your BigQuery datasets and tables to confirm connectivity.

1. Connect **Chat Input** and **Chat Output** components to the **BigQuery** component.

    ![BigQuery component connected to chat input and output](/img/integrations-bigquery.png)

2. Open the **Playground**, and then submit a valid SQL query.

    This example queries a table of Oscar winners stored within a BigQuery dataset called `the_oscar_award`:

    ```sql
    SELECT film, category, year_film
    FROM `big-query-langflow-project.the_oscar_award.oscar_winners`
    WHERE winner = TRUE
    LIMIT 10
    ```

    <details>
    <summary>Result</summary>

    ```text
    film	category	year_film
    The Last Command	ACTOR	1927
    7th Heaven	ACTRESS	1927
    The Dove;	ART DIRECTION	1927
    Sunrise	CINEMATOGRAPHY	1927
    Sunrise	CINEMATOGRAPHY	1927
    Two Arabian Knights	DIRECTING (Comedy Picture)	1927
    7th Heaven	DIRECTING (Dramatic Picture)	1927
    Wings	ENGINEERING EFFECTS	1927
    Wings	OUTSTANDING PICTURE	1927
    Sunrise	UNIQUE AND ARTISTIC PICTURE	1927
    ```

    </details>

    A successful chat confirms the component can access the BigQuery table.

## Google Generative AI

This component generates text using [Google Generative AI models](https://cloud.google.com/vertex-ai/docs/).

Supported models include the Gemini 1.5, 2.0, 2.5, and 3.0 series. The latest Gemini 3.0 models (`gemini-3-pro-preview`, `gemini-3-flash-preview`, and `gemini-3-pro-image-preview`) offer advanced reasoning and multimodal capabilities.

### Google Generative AI parameters

| Name | Type | Description |
|------|------|-------------|
| Google API Key | SecretString | Input parameter. Your Google API key to use for the Google Generative AI. |
| Model | String | Input parameter. The name of the model to use, such as `"gemini-2.5-flash"` or `"gemini-3-pro-preview"`. |
| Max Output Tokens | Integer | Input parameter. The maximum number of tokens to generate. |
| Temperature | Float | Input parameter. Run inference with this temperature. |
| Top K | Integer | Input parameter. Consider the set of top K most probable tokens. |

| N | Integer | Input parameter. Number of chat completions to generate for each prompt. |
| model | LanguageModel | Output parameter. An instance of ChatGoogleGenerativeAI configured with the specified parameters. |

## Google Generative AI Embeddings

The **Google Generative AI Embeddings** component connects to Google's generative AI embedding service using the GoogleGenerativeAIEmbeddings class from the `langchain-google-genai` package.
