LLM evaluations can start with simple test cases, not complex platforms

Developing robust evaluation methods for Large Language Models (LLMs) is crucial for preventing regressions and ensuring consistent performance. Instead of relying on complex platforms, a practical approach involves creating a curated set of real-world failure cases. This set, built from bug reports and past issues, should include expected properties rather than exact outputs. Simple code-based checks for parsing, missing fields, or incorrect categories can catch many common errors, while more subjective qualities like tone or faithfulness can be assessed using LLM-as-judge techniques.

    LLM Evals Start as Thirty Test Cases, Not a Platform

    <p>You tweak a system prompt to fix one bad answer a user reported. You try it on that example, it looks great, you ship. Two days later someone notices the feature now ignores the output format half the time, or started apologizing in every reply, or quietly stopped handling a w…
