The big idea

Did you know real AI agents cost money to run? Each step costs a tiny bit. Smart agents come with a budget — like an allowance — so they don't run forever and waste cash.

Some examples

AI gets $1 to plan a trip — and stops at $1.
AI gets 100 steps and stops at 100.
Without a budget, AI could spend forever.
Budgets keep AI safe and cheap.

Try it!
