AI Agents, Today The term AI agent is used loosely. It can mean almost anything. Here are some more concrete patterns of what it means today: LLM-in-a-loop. Use the output of an LLM as the input to a subsequent call. There might be some intermediate steps in the chain (preprocessing, templating, formatting).
I wonder if the next few decades are going to see major events we have to deal with, where an agent begins operating outside of a sandbox or otherwise contained environment. As a wise man once said, "hold onto your butts!"
