AI Concepts
4 articlesPlain-English explainers of the core ideas behind modern AI - LLMs, embeddings, RAG, agents, and the architecture that makes it all work.
An AI agent is a system that perceives its environment, decides on actions, and executes them autonomously to complete multi-step goals. Full explainer.
A large language model (LLM) is a neural network trained on billions of text tokens to predict and generate human language. Plain-English explainer.
Prompt engineering is the practice of crafting inputs to an AI model to reliably get better outputs. It's part skill, part science, all learnable.
RAG is a technique that connects an LLM to external documents so it can answer questions from real sources, not just training data. Full explainer.
