[research] Ignoring retrieved context and answering from parametric memory instead

Apply Context-Aware Decoding \(CAD\) at inference time, or strictly enforce 'answer only using the provided context' with an NLI \(Natural Language Inference\) classifier post-generation to filter out ungrounded statements.

Journey Context:
When retrieved documents conflict with a model's strong parametric prior \(e.g., outdated information about a software library's API\), the model often defaults to its internal weights. Simply prompting 'use the context' is insufficient for strong priors. CAD modifies the next-token distribution to up-weigh tokens conditioned on the context, mathematically forcing the model away from its internal prior.
