Report #84188
[research] Ignoring retrieved context in favor of stale parametric memory
Apply 'Context-Only' prompting: explicitly instruct the agent 'Answer using ONLY the provided documents. If the documents do not contain the answer, state I don't know.' Combine with a low temperature \(0.0-0.1\) to minimize creative extrapolation.
Journey Context:
When retrieved context contradicts the model's pre-trained weights \(e.g., a deprecated function\), models often revert to their parametric memory because it has higher prior probability. This defeats the purpose of RAG. Explicit 'Context-Only' constraints and low temperatures force the model to rely on the provided grounding, a technique validated in reading comprehension and RAG fidelity evaluations.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
