# Privacy Levels

> The privacy score system Tyk AI Studio uses to control which LLMs, Tools, and Data Sources can be used together.

## Availability

| Edition | Deployment Type |
| :- | :- |
| [Community](/docs/ai-management/ai-studio/overview#community-edition) & [Enterprise](/docs/ai-management/ai-studio/overview#enterprise-edition) | Self-Managed, Hybrid |

Tyk AI Studio assigns a privacy score to LLM configurations, Tools, and Data Sources. This score controls which resources can be used together, so that sensitive data cannot reach a less trusted LLM.

## The Privacy Score Scale

AI Studio stores the privacy score as an integer from 0 to 100. From v2.2.0, the UI shows the score as one of four named levels, together with the number:

| Level | Score Range | Default Score | Typical Use |
| :- | :- | :- | :- |
| **Public** | 0 to 25 | 25 | Safe to share, for example blogs or press releases. |
| **Internal** | 26 to 50 | 50 | Limited to users within your organization, for example reports or policies. |
| **Confidential** | 51 to 75 | 75 | Sensitive business data, for example financials or strategies. |
| **Restricted** | 76 to 100 | 100 | PII or personal data, for example names, emails, or customer records. |

The create and edit forms for LLMs, Tools, and Data Sources have a level selector and a number field. When you select a level, the form sets its default score. You can also enter a different number in the range of the level. Lists, detail pages, the AI Portal, and submissions show the level and the number, for example **Internal · 50**. The API accepts only scores from 0 to 100. Other values return `400`.

## How the Comparison Works

A resource with a higher privacy score than the LLM it is used with cannot be attached to that LLM. For example:

* A **Restricted** (100) Data Source cannot be used with an LLM Configuration whose privacy score is only **Internal** (50).
* A **Public** (25) Tool can be used with any LLM Configuration, since 25 is the lowest score.

This check applies to:

* [Tools](/docs/ai-management/ai-studio/tools) used with an LLM Configuration.
* [Data Sources](/docs/ai-management/ai-studio/datasources-rag) used with an LLM Configuration in a RAG-enabled Chat.
* [Apps](/docs/ai-management/ai-studio/admin-apps), when a user creates an App or an admin edits its resources. The check includes the Tools of the App.
* [Model Routers](/docs/ai-management/ai-studio/model-router). A router has the lowest privacy score of the LLMs that it can reach. The router can send a request to any of these LLMs, so AI Studio treats the router as its least trusted LLM. For example, a router reaches an **Internal** (50) LLM and a **Restricted** (100) LLM. The score of this router is 50. An App with this router cannot have a **Restricted** data source. Otherwise, the router can send that data to the **Internal** LLM.

If a user tries to combine resources that fail this check, Tyk AI Studio blocks the action and shows an error.

## Where You Set a Privacy Score

You set a privacy score when you create or edit:

* An LLM Configuration, under [LLM Management](/docs/ai-management/ai-studio/llm-management).
* A Tool, under [Tools](/docs/ai-management/ai-studio/tools).
* A Data Source, under [Data Sources](/docs/ai-management/ai-studio/datasources-rag).

Community submissions to the [AI Portal](/docs/ai-management/ai-studio/ai-portal) also carry a suggested privacy score from the submitter, which an admin can change before approving the submission.
