Answer: A contextual grounding check with a grounding threshold
A contextual grounding check scores each response for grounding in the supplied source and for relevance to the query, and it treats any new information that is not in the source as ungrounded. Responses that fall below the configured threshold are detected as hallucinations and blocked, and raising the threshold makes the check stricter.
