How to Set a Budget for AI Agents
Budgeting agents is like budgeting any team: know what they spend, cap it, and review it. Four steps, one afternoon.
Step 1 — Inventory
List spend-capable agents and what they buy.
Step 2 — Set ceilings
Per-agent daily ceilings and per-transaction caps.
Step 3 — Split categories
Separate budgets for inference, data, tools, and payments.
Step 4 — Review weekly
Read the audit log, tune one rule at a time.
FAQ
What's a good starting ceiling?
Recent actuals × 1.5, then tighten with the log.
