How do you design an offline LLM eval harness so the numbers are reproducible and comparable?

The same model can score ten points apart on MMLU depending on prompt format and scoring method. The signal is knowing the knobs (log-prob vs generation, few-shot, normalization) that make evals reproducible.

Applied AI Engineering·EvaluationSign in14mBuilding a set of examples worth trustingYour evaluation is only as good as the examples in it, and most sets are quietly useless because of how they were assembled. This lesson covers where to get examples, what proportion should be awkward, and the maintenance nobody plans for.Applied AI Engineering·EvaluationSign in12mWhat to do with a number once you have oneMost teams that build evaluation stop at producing scores. This lesson is the part that makes them useful: reading a change honestly, deciding what would make you revert, and turning a set into something that runs without anyone remembering to.
