# AI and models

Product: AI Universe
Source: https://docs.fortytwo.io/ai-universe/control-panel/ai/

The **AI** tab decides which AI your agents may use, and the rules every question and reply passes through.

## Models

*The AI your agents may use* lists the models deployed in your Microsoft Foundry. Each model has its own price and speed, and every app can use the models added here.

Until at least one model is added, agents have nothing to run on. To add one, turn on **Technical details** in the account menu (see [First sign-in](https://docs.fortytwo.io/ai-universe/get-started/first-sign-in/#the-account-menu)) or ask whoever runs the platform.

**Gateway settings** holds the technical side of the AI gateway: the models it serves, token limits and how long records are kept.

## Safety rules

Every question and reply is checked for four kinds of harmful content: hate, violence, sexual content and self-harm. Choose how strict the check is:

| Level | What it blocks |
|-|-|
| **Strict** | Anything mildly harmful and up. Fewest surprises, most false alarms. |
| **Balanced** | Clearly harmful content. What most organisations run. |
| **Relaxed** | Only the severe cases. For teams whose work involves difficult material. |

To set the four kinds to different levels, choose **Set each kind separately**.

The page also counts the replies blocked in the last thirty days. Each one is a question the rules stopped, not a fault.

## Pause all AI

**Pause all AI** is the platform's off switch. While AI is paused:

- agents stop responding in every app
- app tools stop running

Nothing is deleted and nothing is changed. You are asked to confirm first.

While paused, the page shows *AI is paused*. **Turn AI back on** restores everything as it was.

:::warning[It applies to every app]
Pausing is meant for incidents, for example if you suspect misuse. It stops AI in every app at once. To stop one app's agent, change that app's [Agents](https://docs.fortytwo.io/ai-universe/apps/agents/) settings instead.
