AI agent
Level 2
An AI system that can take steps and use tools to complete a goal, not just answer.
Term 1 of 7 in AI agents
In plain language
An agent is given an objective, then decides what to do next, does it, looks at the result and repeats. The model is still the brain, but it now has hands.
Think of it like this
An assistant who will actually go and book the flight rather than telling you which flight to book.
Why it matters
Agents are where AI stops being a text box and starts changing workflows. They are also where mistakes get expensive.
