Your assistant works beautifully. It answers questions, uses tools, remembers context, and handles complex tasks. But there's a problem you might not have noticed yet: every interaction costs money.

Each time your agent calls Claude Sonnet 4.5, GPT-5, or Gemini 2.5, you're charged based on the number of tokens processed. Input tokens (your prompt) and output tokens (the response) both count. Run your agent at scale, and those costs add up fast. A single user might generate $0.50 in API costs per day. A thousand users? That's $500 daily, or $15,000 per month.

The good news is that you can dramatically reduce costs without sacrificing much capability. This chapter shows you how to build an agent that's both powerful and economical.
