system prompt — The standing instructions a model receives before any user input — defining its role, rules, tools, and tone for the whole conversation.
AI agent — An AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.
inference — Running a trained model to get answers — the phase where AI is actually used, as opposed to trained.
