What is an AI agent?
An AI agent is a software program that perceives its environment, decides what to do, and takes action toward a goal with little or no human input. Unlike a chatbot that only answers, an agent can actually carry out the steps on its own.
A typical agent runs a simple loop. It observes a situation, reasons about the options, acts, then checks the result before deciding what to do next. Most modern agents use a large language model for the reasoning part, with extra tooling added on for memory and for taking action.
Here is the practical difference. A chatbot tells you how to reset a password. An agent logs in, resets it, and confirms the change. That shift from answering to doing is the whole point.
Teams that move past experiments and into production usually need agents wired into real systems, which is the kind of AI and machine learning build Sthenos owns end to end.

Is an AI agent the same as a chatbot?
No. A chatbot responds to messages. An agent takes actions to complete tasks, often across several tools.
