Definition

AI memory refers to a system where an AI model stores and retrieves information from previous interactions. This allows it to maintain context, improve personalization, and build long-term understanding. Unlike context windows, memory can persist across sessions.

Example

“A chatbot that remembers your name and past questions is using AI memory.”

How It’s Used in AI

AI memory is essential in autonomous agents, AI agents, and advanced chat assistants. It enables dynamic interaction across multiple sessions, improves relevance, and can store user preferences or goals. Some systems use vector databases to store and search memory efficiently.

Brief History

Memory systems gained popularity alongside LLMs, particularly with tools like LangChain and OpenAI's persistent memory features introduced in 2023–2024. They aim to make AI more adaptive and conversational.

Key Tools or Models

• LangChain Memory, OpenAI Assistant Memory, ReAct + Memory

• Often used with Weaviate, Pinecone, and Chroma

• Deployed in customer support bots, research agents, and learning tutors

Pro Tip

Good memory needs guardrails. Without checks, AI may recall outdated or wrong data. Always manage and update memory carefully.
