RAG & Retrieval
Faithfulness (RAG Metric)
A RAG evaluation metric that measures how factually consistent a generated answer is with the retrieved context.
In depth
A RAG evaluation metric that measures how factually consistent a generated answer is with the retrieved context. Ragas computes it by splitting the answer into individual claims, checking whether each claim can be inferred from the context, and dividing supported claims by total claims for a score from 0 to 1. A low score means the model added facts the retrieved documents do not support, which is a direct measure of hallucination in a RAG pipeline.
