Frequently asked questions
Practical answers for applying this calculator to a production API billing or usage plan.
What traffic should go to a lower-cost model?
Common candidates include classification, extraction, formatting, simple retrieval, routing decisions, and low-risk drafts that pass quality checks.
How should routing quality be measured?
Use task-specific evaluations, escalation rate, retry rate, latency, and customer outcomes rather than assuming every request needs the strongest model.
Can routing increase cost?
Yes. Poor routing can cause retries, premium fallbacks, or quality failures. Include fallback traffic and evaluation overhead in production forecasts.
