What is an AI agent?
An AI agent is software that uses AI, typically a large language model, to understand a goal, plan the steps, use tools and data to take actions, and check results until the task is done. Unlike a chatbot that only replies, an agent can actually do work in other systems.
How it works
- Receives a goal.
- Gathers context and memory.
- Plans steps.
- Calls tools or APIs.
- Observes results and adjusts.
- Hands off or reports.
