Evaluating changes in large language models (LLMs) and prompts often relies on subjective assessments rather than rigorous statistical methods. Teams should adopt practices like bootstrap confidence intervals and paired significance testing to determine if changes are genuinely improvements or merely random variations. Integrating deterministic checks with LLM-as-judge scoring, alongside treating prompts as versioned code with regression tests, can ensure more reliable and reproducible results in production settings.
