# Concurrency & Quotas

> Concurrency and usage limits that apply to your Beyond Presence plan.

Your plan determines how many sessions you can run at the same time and how many minutes are included each month. Both limits are enforced when a session or call is created.

## Concurrent Sessions

A concurrent session is any agent call or speech-to-video session that is currently running. The limit applies across your whole account, regardless of which avatars or agents are involved.

| Plan       | Concurrent sessions |
| ---------- | ------------------- |
| Free       | 1                   |
| Starter    | 10                  |
| Growth     | 25                  |
| Scale      | 50                  |
| Enterprise | Custom              |

Requests that would exceed your limit are rejected with [`429 Too Many Requests`](/concepts/api/errors#status-codes). Wait for a running session to end, or upgrade to a plan with a higher limit.

## Usage Limits

Each plan includes a monthly allowance of conversation minutes. Beyond that allowance, usage is billed at your plan's overage rate if usage-based billing is enabled.

| Plan       | Included minutes | Overage rate  | Avatar slots |
| ---------- | ---------------- | ------------- | ------------ |
| Free       | 40               | Not available | 0            |
| Starter    | 280              | €0.175 / min  | 1            |
| Growth     | 1,490            | €0.10 / min   | 3            |
| Scale      | 4,000            | €0.0875 / min | 10           |
| Enterprise | Custom           | Custom        | Custom       |

When your allowance is exhausted and usage-based billing is not enabled, requests are rejected with [`402 Payment Required`](/concepts/api/errors#status-codes). Upgrade your plan or enable usage-based billing to proceed.

Each plan also includes a fixed number of avatar slots. If you have reached the limit of your plan, you need to delete an existing custom avatar or upgrade your plan in order to create new avatars.

On the Free plan, individual sessions are additionally capped at 3 minutes.

See the [pricing page](https://www.beyondpresence.ai/pricing) for the current plans, credit allowances, and custom avatar limits.
