AI cost calculatoron-premise · cloud · API

Not all AI spending looks the same. On-premise hardware has a fixed upfront cost but near-zero marginal cost. Cloud compute scales with hours used. API pricing scales with tokens consumed. Adjust your daily usage and token throughput to see which model wins for your workload — and where the break-even points are.
