Frequently asked questions
Are playground tests billed?
Yes. Tests use the signed-in account's balance. The estimated hold is shown before submission, and the final amount is calculated from actual usage and effective pricing.
What happens if a test fails or stops?
Requests rejected before generation have no model usage. Failures, cancellations and interrupted streams are settled or released by the shared ledger. Check the run record for any billable usage already produced.
Where can I see results and charges?
Recent results and actual charges are available in the test history. Open the usage record using its request ID. Download large results promptly.
Pricing
These are standard model prices. Signed-in estimates account for your billing identity and parameters; final charges use actual usage.
