Hosted compute is prepaid. Top up your organization's balance, then OpenResearch deducts instance usage at the underlying provider rate with no OpenResearch markup.
Open the organization's Billing tab. It shows the current balance, in-flight compute charges, and recent activity. Click Top up to add funds.
The In flight tile on the billing page shows an estimate of charges accumulating on currently running instances since their last billed tick.
The Recent activity section shows top-ups, compute and storage charges, refunds, and manual adjustments. Positive entries add to your balance; negative entries deduct from it.
A non-positive balance blocks new hosted instances. Billing continues to check running hosted instances and terminates them after the balance reaches zero, so top up before starting long workloads. Self-managed machines are unaffected; stop those with the provider or through your own tooling.
