Cost Controls: Token Budgets, Tool Budgets, and Model Routing

Budgets are product features

Without budgets, cost surprises will kill your rollout. Set max tokens per run and max tool calls per run.

Model routing

Use small models for classification/routing and large models only when needed.

Cache and reuse

Cache stable answers, summaries, and retrieved docs to avoid repeat costs.
