# Chat with an agent

> Test agents in Agent Chat.

Use Agent Chat to interact with agents and test their behavior before integrating them into your applications.

## Start a conversation

<Steps>
  <Step>
    Navigate to **Playground > Agent Chat** in the sidebar.
  </Step>

  <Step>
    Select an agent from the dropdown. Only active agents appear in the list.
  </Step>

  <Step>
    Type a message and press **Send**.
  </Step>
</Steps>

The agent processes your message and returns a response. If the agent has tools configured, you can see which tools were called during the response.

## Manage threads

Each conversation with an agent creates a thread. Previous threads are saved and accessible from the thread list on the left. To start a new conversation, click the **+** button.

## Model parameters

Use the model parameters panel to adjust how the agent generates responses:

| Parameter         | Description                                                                                                                 |
| ----------------- | --------------------------------------------------------------------------------------------------------------------------- |
| Temperature       | Controls response randomness. Lower values produce more predictable responses; higher values produce more varied responses. |
| Top P             | Controls the range of tokens the model considers. Lower values narrow the selection to more likely tokens.                  |
| Frequency Penalty | Reduces repetition of tokens based on how often they have appeared in the response so far.                                  |
| Presence Penalty  | Reduces repetition of tokens that have already appeared in the response, regardless of frequency.                           |

Click **Reset All to Default** to restore all parameters to their default values.
