AI Agent

ELI5 — The Vibe Check

An AI Agent is an AI system that can think, plan, and act on its own to accomplish a goal. Instead of just answering questions, it breaks down tasks, uses tools, makes decisions, and keeps going until the job is done. It's like the difference between Siri reading you the weather and JARVIS actually handling your entire schedule, ordering lunch, and filing your taxes.

Real Talk

An AI agent is an autonomous system built on top of an LLM that can perceive its environment, make decisions, and take actions to achieve specific goals. Agents typically combine a reasoning engine (LLM), tool access (APIs, code execution), memory (short and long-term), and a planning loop (observe-think-act). They can handle complex, multi-step tasks with minimal human intervention.
