Report #39264
[architecture] Treating the LLM context window as the sole memory mechanism leading to context overflow and high costs
Adopt a tiered memory architecture: L1 \(Context Window\) for immediate working memory, L2 \(Summarization/Sliding Window\) for recent conversational context, and L3 \(Vector/Graph DB\) for long-term semantic memory. Move data between tiers proactively.
Journey Context:
Beginners pass the entire chat history into the LLM until they hit the token limit, then truncate the oldest messages. Truncation destroys early context permanently. A tiered approach mimics human memory: active focus \(L1\), short-term recall \(L2\), and long-term storage \(L3\). When L1 gets full, summarize to L2; when L2 gets old, extract facts to L3. The tradeoff is architectural complexity, but it enables unbounded conversational length while keeping L1 token usage optimized.
