Unlock how Retrieval-Augmented Generation (RAG) enables AI agents to remember, learn, and personalize over time. In this episode, we explore Chapter 17 of Keith Bourne’s "Unlocking Data with Generative AI and RAG," focusing on implementing agentic memory with the CoALA framework. From episodic and semantic memory distinctions to real-world engineering trade-offs, this discussion is packed with practical insights for AI/ML engineers and infrastructure experts.

In this episode:

- Understand the difference between episodic and semantic memory and their roles in AI agents

- Explore how vector databases like ChromaDB power fast, scalable memory retrieval

- Dive into the architecture and code walkthrough using CoALA, LangChain, LangGraph, and OpenAI APIs

- Discuss engineering challenges including validation, latency, and system complexity

- Hear from author Keith Bourne on the foundational importance of agentic memory

- Review real-world applications and open problems shaping the future of memory-augmented AI

Key tools and technologies mentioned:

- CoALA framework

- LangChain & LangGraph

- ChromaDB vector database

- OpenAI API (embeddings and LLMs)

- python-dotenv

- Pydantic models
