# Session Duration

> Control how long persona sessions last and configure greeting behavior

## Duration limit

Control how long a session stays active with `maxSessionLengthSeconds`. The countdown begins when the persona starts streaming.

```javascript theme={"system"}
const personaConfig = {
  name: "Cara",
  avatarId: "30fa96d0-26c4-4e55-94a0-517025942e18",
  voiceId: "6bfbe25a-979d-40f3-a92b-5394170af54b",
  llmId: "a7cf662c-2ace-4de1-a21e-ef0fbf144bb7",
  systemPrompt: "You are Cara, a helpful customer service representative.",
  maxSessionLengthSeconds: 300,
};
```

<Info>
  If you don't set `maxSessionLengthSeconds`, the session continues until manually ended or until it reaches your plan's conversation limit: 3 minutes on Free, 5 minutes on Starter, 10 minutes on Explorer, and unlimited on Growth and above.

### Recommended durations

| Use case         | Duration      | Reason                                       |
| ---------------- | ------------- | -------------------------------------------- |
| Trial / demo     | 2–5 minutes   | Gives users a taste without running up usage |
| Product demo     | 5–15 minutes  | Enough to showcase key features              |
| Customer support | 10–30 minutes | Room for complex issues                      |

### Tips

* Allow enough time for the conversation to conclude naturally — abrupt endings frustrate users.
* Consider showing users a countdown timer so the cutoff isn't a surprise.
* Track actual session lengths to find the right limit for your use case.
