Enter output length, generation speed and time-to-first-token to see how long a response takes and how many responses per minute a single stream can produce.

How this is calculated

This calculator uses the infrastructure formulas described in our methodology. All figures are estimates for planning; verify current pricing with each provider before relying on them.

Frequently asked questions

What is time to first token?+

The delay before the first output token appears. It matters a lot for perceived responsiveness in chat UIs.

How do I get more throughput?+

Batch requests, use faster/smaller models, or add more replicas. See our concurrency planner.
