AI terminology changes quickly, but the underlying ideas are easier to follow when you separate the model from the systems built around it. An LLM, for example, is different from RAG, even though the two are often used together.
This glossary explains the AI terms that show up most often in startup products, technical discussions, and product planning without assuming a research background.
Start with LLMs if you want the model basics, then move to RAG and AI agents to see how models are connected to outside information and tasks.
