# Structural Cloud LLM configuration

## Models used on Structural Cloud <a href="#cloud-ai-models" id="cloud-ai-models"></a>

For its AI-enhanced features, Structural Cloud uses Opus 5, Sonnet 5, and Haiku 4.5 from Anthropic deployed on Amazon Bedrock.

## Configuring AI-based Structural functionality <a href="#cloud-config-ai-features" id="cloud-config-ai-features"></a>

### Opting out of all Structural AI features <a href="#cloud-llm-opt-out" id="cloud-llm-opt-out"></a>

Cloud organizations can choose not to use any Structural AI features.

On the [**Organization Settings** page](/app/admin/environment-variables-setting/structural-cloud.md) of **Structural Settings**, toggle `TONIC_LLM_PROVIDER` to the off position.

### Excluding sample data from LLM-based sensitivity detection <a href="#cloud-ai-exclude-data-llm-detection" id="cloud-ai-exclude-data-llm-detection"></a>

By default, LLM-based sensitivity detection sends both the database schema and sample source data values to the LLM.

To exclude the contextual source data, and only send the schema, on the **Organization Settings** tab of **Structural Settings**, set `TONIC_LLM_ENABLE_ENHANCED_RECOMMENDATIONS_SAMPLE_DATA` to false.

### Disabling LLM-based sensitivity detection in a workspace <a href="#cloud-disable-workspace-llm-detection" id="cloud-disable-workspace-llm-detection"></a>

On Structural Cloud, LLM-based sensitivity detection is enabled by default.

You can disable LLM-based sensitivity detection within individual workspaces.

To do this, in the [advanced workspace overrides](/app/workspace/workspace-configuration-settings/advanced-overrides.md), set `TONIC_LLM_ENABLE_ENHANCED_RECOMMENDATIONS` to false.

LLM-based sensitivity detection also processes LLM-based sensitivity rules. If you disable LLM-based sensitivity detection, then the sensitivity scan does not process any LLM-based sensitivity rules.

### Excluding sample data from all LLM-based Structural features

To configure Structural to not send sample data for any LLM-based features at all, on the **Organization Settings** tab of **Structural Settings**, set `TONIC_LLM_ENABLE_SAMPLE_DATA` to `false`.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.tonic.ai/app/structural-ai-and-agent/structural-ai-use/structural-cloud-llm-configuration.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
