問題文

Your relevance scores dropped after you changed the retrieval configuration, but the groundedness scores stayed the same. Interpret this pattern.

選択肢

1. The evaluator's threshold changed for relevance but not groundedness, so the same responses now fall on the other side of the boundary for one metric while the other keeps reporting the same aggregate as before
2. The context column stopped being passed to the evaluator
3. The application still stays within the context it receives, but that context now addresses the query less well, so the retrieval change made the retrieved material less on-point
4. The generation model was silently updated to a different version
