# Credits & Billing

AI Demo Agents consume **credits** based on usage. This page covers how credits work, session limits, and tips for managing costs.

***

### Credit Usage

| Usage Type          | Description                                                   |
| ------------------- | ------------------------------------------------------------- |
| **Agent responses** | Each AI-generated response (text/voice) consumes credits.     |
| **Voice playback**  | Voice interactions consume additional credits on top of text. |

Credits are tracked at the **workspace level**. Enterprise plans share a credit balance across all workspaces in the organization. Credits are applied and/or discounted based on the volume, which can be discussed over[ a scoping call](https://cal.com/team/supademo/ai-demo-agents), with pricing starting as low as **$0.51-0.70 per \~15 minute demo call.**

#### Grace Buffer

A grace buffer of **2,000 credits** prevents abrupt cutoffs mid-conversation. If your balance dips slightly below zero, active sessions continue until completion. New conversations are blocked once the buffer is exceeded.

### Session Limits

| Limit                      | Value                                       |
| -------------------------- | ------------------------------------------- |
| **Session limit**          | 20 minutes                                  |
| **Inactivity timeout**     | 10 minutes of no activity.                  |
| **Expiry warning**         | Shown 2 minutes before the session ends.    |
| **Daily conversation cap** | Configurable, 1 -- 10,000 (default: 5,000). |

The daily conversation cap is set in Security settings. Active sessions are never interrupted when the cap is reached -- only new conversations are blocked.

### Managing Costs

* **Set a daily cap** -- Use the Max conversations per day setting in Security to prevent runaway usage.
* **Monitor per-session credit usage** -- The Sessions table shows credits consumed by each conversation.
* **Track volume trends** -- Use the Insights dashboard to understand conversation volume over time and spot unexpected spikes.
* **Optimize your knowledge base** -- Better content means fewer back-and-forth messages, shorter conversations, and lower credit consumption per session.
* **Restrict embed domains** -- Limit where your agent can be embedded to prevent unauthorized usage on third-party sites.
