# 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, each tool call is surfaced as it begins running, and tools that run in parallel are surfaced as running in parallel. When an agent delegates to a sub-agent, the sub-agent's execution is surfaced while it runs.

## 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.
