### Usage limits

Usage limits determine how much data you can log, score, and retain, and how much built-in model usage is included with your plan. On-demand rates apply once you exceed the included limits.

<Tip>
  Pro plan on-demand usage rates are lower and provide better economics as your usage scales.

## Model credits

Monthly [model credits](#usage-limits) cover [built-in models](/docs/admin/ai-providers#manage-built-in-models), which you can use without providing your own API key, as well as AI features like [Topics](/docs/observe/topics). After your monthly credits are exhausted, the on-demand token rates below apply.

| Feature                                                                                                                                                                                                                                                                  | Input tokens  | Cached input tokens | Output tokens |

<Note>
  Model credits do not roll over month-to-month. On Starter, if you exhaust your credits and have not [enabled on-demand usage](/docs/admin/billing/change-plan#enable-on-demand-usage), Topics and built-in model usage are paused until the next monthly cycle or until you add a card. Enterprise plans have custom model credits and discounted token rates. [Contact Braintrust](https://www.braintrust.dev/contact) to learn more.
</Note>

## System limits

These limits apply to all users regardless of plan. They ensure platform stability, prevent timeouts, and maintain performance for everyone.

<Note>
  [Self-hosted customers](/docs/admin/self-hosting) can adjust some of these limits. [Contact Braintrust](mailto:support@braintrust.dev) for details.
