Using the right model for the right task cuts costs by 5-10x without sacrificing quality. > **This diagram assumes an unconstrained budget (Max/API).** On tighter plans (Pro, Teams Standard), apply the budget modifier below. ```mermaid flowchart TD A([Task to complete]) --> B{Task complexity?} B -->|Simple| C["Simple tasks:
