Entity normalization
Correct means one canonical record, from any surface form
Names, codes and abbreviations arriving from a dozen upstream systems, all meant to resolve to the same thing. The failure mode is quiet — a near-match that reads as right and is not — so the scoring has to be stricter than a human skim.

Reasoning benchmarks
Correct means the final answer, after multi-step work
Competition math, logic chains, extra-hard tasks. The model can usually do the individual steps; the prompt decides whether it commits to the right ones and leaves enough work on the page to be checked.

Multi-hop QA
Correct means an answer no single passage contains
The evidence is split across documents, so the prompt has to make the model gather before it answers instead of settling for the first passage that looks relevant.

Custom pipelines
Correct means whatever your scorer says it is
Anything you can measure. Point a connector at the backend you already run, bring a labelled set, and the same loop optimizes against your own definition of a good answer.
