Memory in Agents

Part of the AI Engineer Roadmap

In short

Mechanisms (conversation buffers, summarized history, vector-stored long-term memory) that let an agent retain context across a session or across sessions entirely.

How to learn this

  1. 1Implement short-term memory (recent conversation) and compare it to a summarized-memory approach.
  2. 2Add a simple long-term memory backed by a vector store for facts across sessions.
  3. 3Learn the trade-off between memory size, cost, and relevance decay over time.
