問題文
A requirement states that the assistant must not state anything the retrieved passages do not support, and must remain useful. Which set of measures implements the requirement so that it can be verified?
選択肢
- Raise the number of retrieved passages so the coverage is always sufficient.
- Add an output check that blocks any answer containing a sentence not present in the retrieved passages, because a requirement about support is satisfied exactly when every sentence appears in the sources.
- Fine-tune on grounded examples only and report the unsupported-claim rate.
- Instruct and fine-tune the model to answer only from the passages and to say so when they do not cover the question, add an output check for unsupported claims, and track both the unsupported-claim rate and the rate of declines.
