Report #12352

[research] LLM ignores provided retrieval context and answers using outdated or incorrect parametric memory

Enforce strict context adherence by using prompting constraints \('Answer using ONLY the provided documents. If the documents do not contain the answer, state I don't know'\) combined with low-temperature sampling \(e.g., 0.0 - 0.1\) to reduce creative deviation.

Journey Context:
Even with context provided, LLMs often fall back to pre-trained weights if the context contradicts their training data or if the context is long. High temperatures exacerbate this by encouraging novel token paths. Low temperature forces the model to stick closely to the high-probability tokens derived from the immediate context window, though it may make the output less fluent if the context is poorly written.
