A word-overlap check beat a DeBERTa NLI model at spotting RAG hallucinations
I expected the neural entailment model to win. It didn't. I wanted to know how far the cheap, no-API-call hallucination checks get on real RAG output before you need an LLM judge or a human. So I built three small detectors, ran them on RAGTruth , and compared them. The one that costs microseconds…
