Free tool · The Tradeoff Calculator

Fast, cheap, good. Pick two, and name the third.

Set your priorities for an AI system. The calculator tells you which dimension must give way, what that usually means in practice, and which questions to settle before anything is built.

The calculator

Set your priorities. See the price.

A value of 70 or more counts as a strong priority. At most two can be strong at once.

Start from an example:
Position of your priorities inside the fast, cheap, good triangle Fast50 Cheap50 Good50
50

Response time. High means answers in well under a second.

50

Cost per request and infrastructure. High means a tight budget.

50

Accuracy and reliability. High means errors are expensive.

Where it fits

Settle before you build

    A planning aid, not a benchmark. Real latency, cost and accuracy depend on your data and workload, so measure them before you commit.

    Why it matters

    Most AI failures are expectation failures.

    A system that is fast and accurate costs more. One that is cheap and accurate takes longer. One that is fast and cheap gives up some quality. None of this is a defect. It becomes a problem only when nobody said it out loud.

    Writing the constrained dimension down, before the build, lets everyone agree on what the system will and will not do. That is how TERA products are built.
