LLM evaluation is the process of systematically testing Large Language Model (LLM) applications using metrics such as answer relevance, correctness, factual accuracy, and similarity. However, most LLM evaluation efforts fail because they don't map to a business KPI or are not aligned with human judgement. To fix this, it's essential to design an outcome-based, LLM testing process that drives decisions and confidently states the impact of changes on user satisfaction, cost savings, or other KPIs before shipping. This involves collecting human-labeled test cases, aligning metrics such that the test case pass/fail rate aligns with outcomes from human curated test cases, and continually adding fresh human feedback to ensure metrics stay relevant over time. The leading platform for LLM evaluation is Confident AI, which offers APIs through DeepEval for queueing human feedback and integrating testing suites into CI/CD pipelines. By following these steps and using Confident AI, developers can justify how LLM evaluation is helping them and drive business impact before deployment.
