The Real Cost of AI Agents Is Not the Model Bill

Short summary

AI agent costs extend far beyond model tokens—each tool call, retry, webhook, and storage operation adds up silently across multiple vendors. Create a tool inventory, map per-call costs, audit all retry paths, set hard run-time budgets, and enable provider-level spend caps before production.

• •Model costs are typically 5–10% of total agent spend; tools, retries, and webhooks hide the rest
• •Webhook fan-outs, retry loops without backoff, and storage writes compound costs silently across vendors
• •Audit tool lists, map pricing, verify retry bounds, set hard budgets, and enable provider-level caps
