32. Cost Control and Token Budgeting

Avoid surprise costs and keep workflows efficient.

The lesson

Cost comes from input tokens, output tokens, model price, and repeated attempts. Long context and large outputs cost more.

Use cheap models for drafts, trim irrelevant context, ask for concise output, and reserve premium models for high-risk work.
