Functions
Definition
Named, reusable pieces of code that perform specific actions; an AI agent can request a function by supplying the inputs it needs.
Visual example
Special station = function
The kitchen connection
Think of a specialized kitchen station that takes an order ticket and returns one finished step.
The illustration connects the AI idea to something familiar. Follow the subject, the action, and the result to see how it works.
- 01 · Who or what
- Special station = function
- 02 · What happens
- Takes inputs and performs action
- 03 · The result
- Returns one useful result
Why it matters
They give agents precise actions, like calculating a price or checking inventory. The model requests the call; application code runs it and should check inputs and permissions.
