Report #86822
[architecture] Over-engineering memory by writing every conversational turn to a vector database, causing retrieval noise and latency for single-session tasks
Use a tiered memory strategy: keep the current session's context entirely in the LLM context window. Only persist to a vector store \(long-term memory\) upon session termination or when the context window limit is reached, and only after summarization or entity extraction.
Journey Context:
The hype around RAG makes developers default to vectorizing everything immediately. However, LLM context windows are now large \(128k\+\). For a single session, in-context retrieval is 100% accurate and zero-latency. Vectorizing intra-session turns creates duplicate or conflicting chunks \(the 'raw chat dump' problem\). Summarizing at session end extracts high-signal entities, reducing long-term memory bloat and preventing the agent from retrieving its own out-of-context conversational filler.
