Credit
A credit is a vendor-defined billing unit. Its relationship to prompts, targets and repeat collections depends on the service and contract. Nostimates pricing and limits are discussed during manual onboarding.
For a simple per-collection model, estimate volume as prompts × targets × samples × runs per month; this is a planning model, not a published Nostimates billing rule.
Because sample count multiplies directly into cost, sampling depth is a budget decision as much as a statistical one.
