Report #93392

[research] Model answers from parametric memory instead of provided retrieved context, contradicting the context

Use strict prompt engineering \(e.g., 'Answer using ONLY the provided documents. If the documents do not contain the answer, state I don't know'\) and implement a faithfulness classifier or attention-based consistency check between the output and the context.

Journey Context:
When retrieved context conflicts with the model's pre-trained weights, the model often defaults to its parametric memory, especially if the context is complex or poorly formatted. Simply appending context doesn't guarantee grounding. Explicit negative constraints combined with automated faithfulness scoring \(like RAGAS faithfulness metric\) are required to enforce context adherence.
