Billing & usage page
Usage and Billing are managed in Settings. Usage shows what you have consumed; Billing manages the plan behind it.
Where to find them
Both are tabs in Settings: Usage and Billing. The tabs you see depend on your role: Usage is open to owners, admins and members; Billing is shown to the owner and, read-only, to admins.
Usage
The Usage tab shows your workspace consumption at a high level — for example the number of prompts used, with a daily breakdown over a recent period that you can export.
Usage helps you keep an eye on activity and stay within your plan.
Billing
The Billing tab shows your current plan and subscription and is where the workspace owner manages or upgrades it. Managing billing is limited to the workspace owner; an admin can read it.
Limits and pricing
Exact allowances and prices depend on your plan. For current numbers, see the in-app Pricing page. The Billing & Limits section covers quotas, over-quota behavior, and upgrades in more detail.
