Agentic AI: Choose Short-Term vs Long-Term Memory Without Building Both
Most agents do not need a vector database — pick the simplest memory that solves the actual recall problem in front of you.
9 min · Reviewed 2026
The premise
Teams reach for vector stores too early; scratchpads, summaries, and structured task state solve most agent memory needs with less complexity and clearer behavior.
What AI does well here
Distinguish working memory, task memory, and durable memory
Recommend the cheapest store that meets the recall need
Show when summarization beats retrieval
Outline a migration path if you outgrow it
What AI cannot do
Operate your retrieval index
Decide your privacy retention policy
Tell you whether your traffic justifies a vector DB
