AI cost and latency trade-offs

Cost-and-latency trade-offs are the choices between model size, prompt length, caching, fine-tuning, and routing that determine the per-request cost and response time of an AI feature.

Why interviewers test it

AI features that work in the prototype break in production when the math meets real traffic. Interviewers test whether you've thought about token cost, p95 latency, and tier routing.
