2707 questions of the kind that actually get asked — in interviews, in architecture review boards, and by the person who has to run the thing at 3 AM. Every answer states the trade-off rather than the slogan, and says when the obvious choice is the wrong one.

A product embeds model calls in several features and spend is growing unpredictably. What controls actually bound it?

A travel platform's AI feature costs vary enormously between interactions and the total is growing faster than usage. Which levers apply, in what order?

An AI feature launched two months ago now costs more per month than the rest of the platform. What do you investigate?

An AI feature was modelled at £0.02 per interaction. Production shows £0.11. Where did the difference come from?

An inference platform receives a burst of expensive long-context requests that would starve short interactive ones. Design admission control, priority classes, token-based limits and batching so interactive latency SLOs hold.
