How Do AI Agent Systems Work?

Modern AI agents usually follow a three-step workflow:

1. First, an LLM determines the goal based on a user-provided prompt.

2. Next, an LLM figures out how this goal can be achieved by breaking it down into smaller, simpler subtasks and gathering the required data, usually by using tools (e.g., accessing your calendar to see when you are available).

3. Finally, the system executes the tasks by using the collected data and the tools available to it.
