# Rate limits

LLM Gateway is rate limited per model, measured as requests within a 60-second window.

| Account type | Rate limit (requests/min, per model) |
| ------------ | ------------------------------------ |
| Free         | Not available                        |
| Paid         | 30                                   |

<Note>
  **Need a higher rate limit?**

  If you need a higher rate limit, [contact our support team](mailto:support@assemblyai.com).
</Note>

## Response headers

If you exceed the limit, the API responds with a `429` status code. To see your remaining quota, check the following response headers:

| Header                  | Description                                                                                |
| ----------------------- | ------------------------------------------------------------------------------------------ |
| `X-RateLimit-Limit`     | Maximum number of allowed requests in a 60 second window.                                  |
| `X-RateLimit-Remaining` | Number of remaining requests in the current time window.                                   |
| `X-RateLimit-Reset`     | Number of seconds until the remaining requests resets to the value of `X-RateLimit-Limit`. |
| `X-RateLimit-Model`     | The model the rate limit applies to. Same as "model" param in the request.                 |
| `X-RateLimit-Service`   | Denotes the service used, LLM Gateway or Speech Understanding.                             |

If the response doesn't include `X-RateLimit` headers, the endpoint doesn't have rate limits.
