What are the benefits of using an LLM-as-Judge approach?

LLM-as-Judge allows you to automate qualitative assessments—such as tone, helpfulness, and nuance—by using a more capable model to grade outputs, providing a scalable alternative to manual human review.

How can I detect performance regressions in my LLM?

This skill includes a RegressionDetector that compares new evaluation scores against a baseline. It flags significant drops in performance based on a configurable threshold, helping you catch errors before they hit production.

Does this skill support statistical significance testing?

Yes, it includes an A/B testing framework that calculates p-values and Cohen's d effect sizes, allowing you to determine if a model improvement is statistically significant or just random noise.

Which metrics are best for evaluating RAG applications?

For RAG, you should focus on retrieval metrics like MRR and NDCG for the search component, and generation metrics like groundedness and faithfulness to ensure the AI stays within the provided context.
