Giving Your AI Agent a Budget (Time, Money, or Tries)

Without limits, an AI agent could try forever, spend lots of money, or fill up your inbox. Smart designers give agents a budget: only so many tries, dollars, or minutes.

Some examples

• 'Try only 5 times before stopping.'
• 'Spend no more than $1 on this task.'
• 'Finish in 10 minutes or stop.'
• 'Send no more than 3 emails today.'

Try it!

Pick a chore. Set yourself a 5-minute timer. When it dings, stop — even if you're not done. That's a 'budget.'

Three kinds of budgets for AI agents

When grown-ups send AI agents to do tasks, they have to set budgets — not just money budgets, but three different kinds. The first is a money budget: 'Spend no more than two dollars searching for this information.' The second is a tries budget: 'Try this task at most five times before giving up and asking me.' The third is a time budget: 'If you haven't finished in ten minutes, stop and report back.' Without any of these, an AI agent could loop forever, spend a fortune in API costs, or keep sending broken emails trying to fix its own mistakes. Think of it like sending a younger sibling to buy snacks. You'd probably say 'here's five dollars, buy chips, and come back in ten minutes.' That's a money budget, a task limit, AND a time limit all in one sentence. Great AI design works the same way.

• Money budget: set a maximum dollar amount the agent can spend on API calls or purchases
• Tries budget: set how many times the agent can attempt the same step before stopping
• Time budget: set a hard deadline so the agent quits and reports instead of running forever
• Scope budget: limit how many files, emails, or records the agent is allowed to touch
