Report #3399

[research] RAG still hallucinates because the generator drifts away from retrieved evidence

Use context-aware decoding to up-weight tokens supported by retrieved context, and require the model to quote or closely paraphrase the evidence rather than relying on parametric memory.

Journey Context:
Retrieval-Augmented Generation reduces but does not eliminate hallucination: models often ignore, misattribute, or contradict retrieved passages, especially when their parametric prior is strong. 'Trusting Your Evidence' shows that biasing the decoder toward context-supported tokens measurably reduces hallucination. The key design choice is to make generation a function of evidence first, model prior second—use attribution prompts, constrained decoding, and explicit quote extraction.
