Choose an LLM

Pick the cheapest AI model that passes your tests

This skill helps you choose a model for one AI workflow with a small test set instead of by impression. You collect 20 to 50 real examples with correct answers, decide pass or fail rules first, run candidate models from smallest to largest, and record pass rate, cost per 100 runs and latency. It then picks the cheapest model within an agreed margin of the best and writes a routing rule, such as escalating to a larger model when confidence is low. You get a results table per workflow and a routing rule to re-test when models or prices change.
