Stop Summarizing Agent History. Retrieve Structured Memory Instead.

Summarization buffers were a workaround for limited context windows. With proper memory architecture, retrieval beats summarization on every metric: fidelity, cost, latency, debuggability. MemoryLake makes structured retrieval the default — and summarization optional, not architectural.

The problem: summarization-as-memory is a workaround that became architecture

Long history wouldn't fit in the context window, so teams summarized. Summarization lost detail, so they summarized less aggressively. The summary chain became the architecture. Now changing it feels expensive. But the cost of staying with summarization is higher.

How it works for retrieval-first agent memory

  1. Connect — Replace summary chain with MemoryLake writes per turn.
  2. Structure — Memory writes typed by content.
  3. Reuse — Per-turn retrieval pulls relevant memory.

Who this is for

Engineering teams running production agents with summary-based memory who realize the workaround has become architectural — and the cost of staying is higher than the cost of switching.
