# Pricing

> Simple credit-based plans. Unlimited users on every tier.

Plans are priced on AI usage, not seats — invite your whole team on any tier. **1 credit = \$1 of AI compute at cost**: what the model providers charge is what's deducted, with no markup.

## How usage works

* Credits reset monthly on your subscription anniversary; unused credits don't roll over.
* **Free** stops at its cap. **Pro** and **Max** can opt into overage with a spending limit you set in **Settings → Billing**; overage is billed at cost.
* Sandbox compute is included in every plan — credits only meter AI usage.
* With [BYOK](/agent-config/byok) (Max), model usage goes on your provider bill and consumes no credits.
