Evaluation Set
A set of test samples with reference answers or expected results, used to quantitatively evaluate the performance of an AI model or application. It typically contains from several dozen to several hundred samples covering core scenarios.
Timeline (last 90 days)
For AI products with probabilistic outputs, establishing a small-scale (tens to hundreds of entries) but stable evaluation set covering core scenarios drives iteration better than blindly pursuing larger models.
Skills such as designing evaluation sets, hallucination detection, and building regression tests to monitor model behavior are extremely scarce in engineering teams.
The Judge-driven quality loop consists of five steps: calibrate the Judge with human annotations, flag low-scoring outputs, confirm real failures, add them to the evaluation set, and fix and rerun.
OpenAI is building both the evaluation set and optimizing the model this time, aiming to break the vicious cycle of low-resource languages lacking benchmarks so that improvements have a basis.
The PM's prompt modifications must first pass on the evaluation set before going live, including several complete Agent runs to detect tool selection drift.
The advice for engineers is: before tuning any RAG parameters, first write a good evaluation set, use the research work the law firm's team has already done by hand as a benchmark, measure precision and recall, and add an audit of missed cases.
When many teams use standard evaluation sets, they only care about whether the model can answer correctly, not about where the answer is located in the context, which is a high-incidence area for problems in production environments.
