How Much Do Legal RAG Systems Still Hallucinate?
This is a reality check on production RAG in a domain where mistakes have real consequences. The finding that no system is uniformly good, and that false-premise questions break even the best ones, matters if you're deploying legal AI. The lesson: RAG alone doesn't solve hallucination in law. You need a human loop or a classifier that catches the bad cases, and this paper gives you a baseline to test against.
