You are a manual agent to LLMs when you use things like ChatGPT. You go through a workflow loop when you try to investigate and consult with an LLM. Agents are just trying to automate your workflow against an LLM. It's basically just scripting. Scripting these LLMs is where we all want to go, but the context window length is a limiting factor, as well as inferencing on any notable sized window.

I'll manage my whiney emotions over the term Agents, but you'll have to hold a gun to my head before I embrace "Agentic", which is a thoroughly stupid word. "Scripted workflow" is what it is, but I know there are some true "visionaries" out there ready to call it "Sentient workflow".
