Your AI Evaluation Can Pass Every Test and Still Mislead You

Описание и применение

Passing тесты eval-кода не означают, что модель дает надежные ответы. Автор проекта OpenAI JS SDK документации learnt разделение тестированияipeline и проверки качества ответов. Теперь он четко разделяет pipeline-correctness и answer quality, точно标注 simulated и live результаты, рассматривает балки как证据, а не верду, и использует контрольный список для точного документирования выводов.

Задача

A passing test suite can tell you that your evaluation code works, but it cannot by itself tell you that your AI model produces reliable answers. Testing the evaluation pipeline is not the same as validating the model.

Результат

The author learned that testing the evaluation pipeline is not the same as validating the model. A passing test suite proves code correctness but does not prove answer quality. The author now separates pipeline correctness from answer quality, accurately labels simulated versus live results, treats scores as evidence rather than verdicts, and uses a checklist to make evaluation claims more precise.

Рабочий процесс

• Build an evaluation workflow including a rule-based baseline, pairwise comparisons, and an optional live-model judge runner
• Test whether the evaluation software processes inputs, applies comparison rules, produces results, and handles failures as expected
• Ask what behavior is being measured, what behavior is not being measured, whether a bad response could pass, whether a good response could fail, and whether examples represent user cases
• Label simulated comparison results separately from live-model judge results
• State what results do not prove when presenting evaluation evidence
• Use a checklist to separate: tested software behavior, explained evaluation criteria, identified result type (rule-based, simulated, or live model), stated what results do not prove, and avoided presenting unverified work as completed validation

Testing the evaluation pipeline is not the same as validating the model.

Источник

For example, a rule that checks whether a response contains a specific phrase might work perfectly in every test while still accepting an incorrect answer or rejecting a correct one written differently.

Источник

Before trusting an evaluation result, ask: What behavior is being measured? What behavior is not being measured? Could a bad response pass? Could a good response fail? Do the examples represent the cases users will encounter?

Источник

If the live evaluation has not been run and validated, the correct report is that live-model validation remains unverified—not that the system has passed a live benchmark.

Источник

Pairwise evaluation can identify which of two responses performs better under a given criterion. But a relative winner is not automatically correct, safe, or production-ready.

Источник

This checklist does not make an evaluation perfect. It makes the claims around it more precise.
