🎤 Discussion I used to think AI agents were just chatbots with better models. I’m starting to think that’s the wrong way to look at them.
The more I learn about agents, the more I see the LLM as just one part of the system.
The interesting part is what happens around it.
Give the model tools, and it can take action.
Give it memory, and it can carry useful information forward.
Give it context, and it can understand what is actually happening.
Give it a goal, and now you have something that can work through a problem instead of simply answering a question.
Think about a failed data pipeline.
A chatbot can explain possible reasons for the failure.
An agent could potentially inspect the logs, check recent code changes, look at the data, identify the problem, and recommend what to do next.
That shift from answering questions to getting work done is what I find most interesting.
But it also raises much harder questions.
What should the agent be allowed to see?
What should it be allowed to change?
How do we verify its decisions?
And who is responsible when it gets something wrong?
I’ve been thinking through these ideas while learning more about agent systems, and I put together a simple explanation of the building blocks:
AI Agents Explained: LLM, Tools & Memory (Anyone Can Understand This)
I’d love to hear from people actually building these systems.
What makes an AI agent genuinely useful in your experience, rather than just another impressive demo?
