The billing page in your workspace settings has two new capabilities: a model usage dashboard and invoice history panel.
Your model usage dashboard breaks down the billable time and total cost of each active model in your workspace. Usage is tracked by version for models with multiple versions, including deleted versions.
If your account has credits, they will be applied against your bill automatically and shown in the model usage dashboard.
For previous billing periods, use the invoices panel to track and download prior invoices. Total bills shown are net of free credits.
