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

​
Feature availability

The following table shows features that vary by plan. Features not listed here are available on all plans without restrictions.
Legacy plans: If you signed up before March 16, 2026, you may retain access to features you created even if they’re not listed as available on your current plan tier. See Legacy plans FAQ for details.

​
Support

All plans include community support.

​
Model credits

Monthly model credits cover built-in models, which you can use without providing your own API key, as well as AI features like Topics. After your monthly credits are exhausted, the on-demand token rates below apply.
Model credits do not roll over month-to-month. On Starter, if you exhaust your credits and have not enabled 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 to learn more.

​
System limits

These limits apply to all users regardless of plan. They ensure platform stability, prevent timeouts, and maintain performance for everyone.
Self-hosted customers can adjust some of these limits. Contact Braintrust for details.
