# Structural AI features

{% hint style="info" %}
AI features are currently only available on:

* The United States deployment of Structural Cloud.
* On self-hosted instances that [connect to a Structural-supported LLM](https://docs.tonic.ai/app/admin/structural-ai-use/connecting-a-self-hosted-instance-to-an-llm).

They are not yet available on the European deployment of Structural Cloud.
{% endhint %}

Tonic Structural currently offers the following AI features.

## Structural Agent

The [Structural Agent](https://docs.tonic.ai/app/structural-agent/agent-about) is a chat-based AI assistant that helps you to configure your workspace for data generation.

## LLM-based sensitivity detection

During sensitivity detection, the [LLM-based detection process](https://docs.tonic.ai/app/generation/identify-sensitive-data/running-the-structural-sensitivity-scan#llm-based-sensitivity-detection-medium-confidence) sends the following information to an LLM:

* Database schema
* Sample source data values. You can [opt to exclude the source data values](#llm-detection-exclude-sample-data).

On a self-hosted instance, the process first retrieves the provider configuration.

## Custom Categorical value creation

For the [Custom Categorical](https://docs.tonic.ai/app/generation/generators/generator-reference/custom-categorical) generator, you can provide a prompt for the LLM to use to create the available values.

For example, `1,000 common pharmaceuticals`.
