RAG drift detection method isolates generator swaps from other system changes

A technical blog post details a method for detecting drift in Retrieval-Augmented Generation (RAG) systems when switching between large language models. The author proposes using the `ragvitals` library to monitor five independent drift dimensions: QueryDistribution, EmbeddingDrift, RetrievalRelevance, ResponseQuality, and JudgeDrift. By carefully separating live traffic from reference probes, the system can accurately identify that only ResponseQuality changed when the generator was swapped from Claude Sonnet to Gemma 4 9B, avoiding false alarms on other dimensions.
