export const largeLanguageModelId_0 = undefined

<a href="/release-notes/2026.9"><Badge className="version-badge" color="blue">Added in 2026.9</Badge></a>

To start using a Google GenAI model with Cognigy.AI features, follow these steps:

1. [Add a Model](#add-models)
2. [Apply the Model](#apply-the-model)

## Add Models

You can add a model using one of the following interfaces:

* [GUI](#add-models-via-gui)
* [API](#add-models-via-the-api)

### Add Models via GUI

You can add a model provided by Google GenAI to Cognigy.AI in **Build > LLM**. To add the model, you will need the following parameters:

If you have previously used a key for the Google Vertex AI or Google Gemini connection, you can reuse this key for Google GenAI. If you're setting up the connection for the first time, go to the Google Cloud console and find Vertex AI via the search bar. On the **Vertex AI** page, click the **Enable All Recommended APIs** button to activate an API connection, if it is not activated. Ensure that the Vertex AI API is enabled. In the left-side menu, go to the **IAM & Admin > Service Accounts**. Select **Actions** and click **Manage Keys**. On the **Keys** page, select **Add Key** and click **Create new Key**. In the appeared window, select the **JSON** key type and click **Create**. The file will be downloaded. |

### Add Models via the API

You can add either a standard or custom model using the [Cognigy.AI API POST /v2.0/largelanguagemodels](https://api-trial.cognigy.ai/openapi#post-/v2.0/largelanguagemodels) request.
Then, test your connection for the created model via the [Cognigy.AI API POST /v2.0/largelanguagemodels/{largeLanguageModelId_0}/test](https://api-trial.cognigy.ai/openapi#post-/v2.0/largelanguagemodels/-largeLanguageModelId-/test).

## Apply the Model

To apply a model, follow these steps:

1. In the left-side menu of the Project, go to **Manage > Settings**.
2. Go to the section based on your use case for using a model:
   * **Generative AI Settings**. In the **Generative AI Settings** section, activate **Enable Generative AI Features**. This setting is toggled on by default if you have previously set up the Generative AI credentials.
   * **Knowledge AI Settings**. Use this section if you need to add a model for Knowledge AI. Select a model for the **Knowledge Search** and **Answer Extraction** features. Refer to the [list of standard models](https://docs.cognigy.com/ai/empower/llms/model-support-by-feature/) and find the models that support these features.
3. Navigate to the desired feature and select a model from the list. If there are no models available for the selected feature, the system will automatically select **None**. Save changes.
