# Agents overview

> What an agent is in Calibrate, the two ways to set one up, and the tabs on an agent page

<video controls src="https://mintcdn.com/amandalmia/eC2smNZTZjZjvk8E/videos/app-agents-overview.mp4?fit=max&auto=format&n=eC2smNZTZjZjvk8E&q=85&s=bfd23cbc874e8ee513b8da23312791ce" />

An agent is the AI you want to test. In these docs the agent is a maths tutor for class 6 students. It explains one step at a time and replies in English or Hindi.

You add the agent to Calibrate once. Then you write tests for it, run them, compare models, and run simulated conversations with it.

## Open your agents

From the sidebar, click **Agents**. The list shows every agent in your workspace.

The **Type** column shows how each agent was set up. **Agent** means it was built in Calibrate. **Connection** means Calibrate calls your own agent at its URL.

## Two ways to set up an agent

Click **New agent**. Give the agent a name, then pick one of the two options under **Setup**.

> You write the instructions, pick the LLM, speech-to-text and text-to-speech models, and add tools. All of it lives in Calibrate.

> Your agent already runs somewhere else. You give Calibrate its URL, and Calibrate sends it messages to run tests, model comparisons and simulations.

>
> See [Connect your own agent](https://docs.calibrate.artpark.ai/core-concepts/agent-connections.md).

Click **Next**. Then choose what your agent does:

* **Conversation**: your agent has a conversation with a user. The maths tutor is this kind.
* **Basic**: the agent takes an input and gives back an output.

Click **Create** to open the agent page.

## Tabs on an agent page

Each agent page has a row of tabs. Which tabs you see depends on how the agent was set up.

| Tab | Build in Calibrate | Connect your own | What it is for |
| - | - | - | - |
| **Agent** | Yes | No | The system prompt and the models. See [Build an agent in Calibrate](https://docs.calibrate.artpark.ai/core-concepts/agents.md). |
| **Connection** | No | Yes | Your agent's URL, headers and the connection check. See [Connect your own agent](https://docs.calibrate.artpark.ai/core-concepts/agent-connections.md). |
| **Tools** | Yes | Yes | The tools the agent can call. See [Add tools to an agent](https://docs.calibrate.artpark.ai/core-concepts/tools.md). |
| **Tests** | Yes | Yes | The tests for this agent. See [Evaluate your agent with unit tests](https://docs.calibrate.artpark.ai/app/agents/tests.md). |
| **Evaluations** | Yes | Yes | Past test runs and model comparisons. It appears after your first run. See [Run unit tests](https://docs.calibrate.artpark.ai/app/agents/tests.md#run-unit-tests). |
| **Evaluators** | Yes | Yes | The evaluators that score this agent's replies. See [Evaluators overview](https://docs.calibrate.artpark.ai/app/evaluators/overview.md). |
| **Monitoring** | Yes | Yes | What your agent does in production. See [Monitor your agent in production](https://docs.calibrate.artpark.ai/app/agents/monitoring.md). |
| **Settings** | Yes | Yes | Who speaks first, the turn limit, and monitoring. |

Click **Save** at the top right of the agent page to keep your changes.
