- 发生了什么
- Researchers propose exposure accounting to measure whether language models actually reason over retrieved knowledge or simply copy visible context.
- 为何重要
- Matters for engineers building retrieval-augmented generation systems who need honest evaluation of whether grounding actually improves reasoning.
- 注意
- The method identifies what was exposed in context but cannot definitively prove reasoning occurred; most grounded gains disappear when measured against copy baseline.
