Report #100711

[architecture] Should I retrieve document chunks into context or just pass the full document?

Default to retrieval for large corpora and sparse facts; use full-context only for small documents or tasks that require global structure. Retrieve longer units and fewer chunks, then rerank. Monitor retrieval-exclusive accuracy—no single strategy wins everywhere.

Journey Context:
Long-context models are simpler but costly and suffer attention dilution; RAG cuts tokens and hallucinations but retrieval errors cascade. A large-scale evaluation across ~20k questions found LC often outperforms chunk-based RAG, yet RAG still uniquely answers ~10% of questions. The right call is workload-dependent, not a universal rule.
