From inputs to a decision
Map your RPS and tokens-per-request to provider RPM/TPM caps so you know headroom before throttle errors hit production.
- 01
Enter expected RPS and tokens per request.
- 02
Add provider RPM and TPM limits if known.
- 03
Run to see utilization, headroom, and suggested max RPS.
Tips for better results
- Plan for burst peaks, not only steady-state averages.
- Use the same prompt pack and RPS when comparing models.
- Estimates use list prices — negotiate enterprise rates separately.
Frequently asked questions
- What does headroom mean here?
- Headroom is unused capacity under the tighter of your RPM or TPM limits at the traffic you entered.
