RAG's blind spot: retrieved context piles up statically as multi-step reasoning grows

burkov · x · 2026-10-20

Burkov highlights an article on a fundamental RAG weakness: retrieved information is treated statically, simply appended to context, so irrelevant, redundant, or conflicting details accumulate and compound as the reasoning chain grows.

Existing approaches focus almost entirely on what enters the system — better queries and retrieval strategies — while neglecting how information should be actively managed, consolidated, and maintained throughout multi-step reasoning. Memory-augmented systems offer only partial remedies via coarse summarization and static knowledge.
