Vector Databases Explained for AI Agents
Learn how vector databases store embeddings, power semantic search, and support RAG and memory without replacing a knowledge base or relational database.
Learn how vector databases store embeddings, power semantic search, and support RAG and memory without replacing a knowledge base or relational database.
A beginner-friendly mental model of embeddings, vectors, similarity, and how AI agents use them for retrieval and memory without confusing similarity with truth.
A practical comparison of external knowledge retrieval and agent memory, including their overlap, different data lifecycles, and shared vector infrastructure.
Build a genuine AI task agent in plain Python with tool calling, observations, state, guardrails, logging, error handling, and tests.
Learn how AI agents use feedback, critique, and execution review to detect mistakes, revise their approach, and improve results without endless retry loops.
Learn how AI agent memory works, from context windows and working memory to persistent stores, retrieval, updating, forgetting, and memory quality.
A beginner-friendly breakdown of the model, instructions, tools, memory, state, planning, feedback, guardrails, and execution loop inside an AI agent.
Follow the seven-stage execution loop that lets an AI agent reason, choose actions, use tools, learn from results, and keep working toward a goal.
A practical explanation of what makes an AI agent different from a chatbot or fixed workflow, and how the agent loop turns model reasoning into action.
