Question 1

What are the types of memory in AI agents?

Accepted Answer

AI agents typically use short‑term memory for the current interaction and long‑term memory to keep information across sessions. Long‑term memory is often split into episodic (past events), semantic (facts and rules), and procedural (skills and workflows) memory so agents can recall history, domain knowledge, and learned behaviors more precisely. In multi‑agent systems, teams also add a shared or team memory layer, where several agents read and write to a common store (a “blackboard”) to coordinate on the same state.

Question 2

What is the best memory architecture for multi‑agent systems?

Accepted Answer

The most effective pattern for multi‑agent systems today is a hybrid memory architecture that combines private and shared memory. Each agent keeps its own scoped memory (short‑term and long‑term) plus access to a shared “blackboard” layer for team‑wide context, all backed by a mix of key‑value stores, vector search, and sometimes graphs or event logs. This design gives better coordination than fully isolated memories and better safety and control than a single global store, while scaling more predictably as you add agents.

Question 3

How do I decide what belongs in short‑term vs long‑term memory?

Accepted Answer

Use short‑term memory for anything the agent needs only to complete the current objective: recent turns, tool outputs, and ephemeral variables. Promote data to long‑term memory when it represents reusable knowledge: user preferences, decisions with future impact, or domain facts that should survive across sessions.

Question 4

Does Greennode support ai agent memory training?

Accepted Answer

Yes. GreenNode supports AI agents with memory by offering AgentBase as its fully managed platform for deploying and operating agents, including a dedicated Memory module for memory.The Memory module specifically acts as the memory layer: it stores session memory for agents and can promote that session data into long‑term semantic memory that is searchable, so your agents can “remember” and reuse past interactions instead of starting from scratch every time. So while GreenNode does not “train” a separate memory model in isolation, it does provide AgentBase + Memory as an integrated way to manage and persist agent memory (session and long‑term) as part of a production‑grade, fully managed platform.
