Use multi-model strategies for cost and intelligence balance
Combine lower-cost and frontier models to optimize expenses while maintaining high intelligence.
Multi-model strategies pair a lower-cost model with a frontier model so that most tokens are billed at the lower rate.
Reduces overall token costs by leveraging cheaper models for the majority of tasks.
Implement patterns like an 'executor' that escalates difficult decisions to an 'advisor' (frontier model), or an 'orchestrator' that delegates bulk work to 'workers' (lower-cost models).
Reduce AI costs by using a combination of models. Employ cheaper models for most tasks and reserve powerful, expensive models for complex decisions or critical steps.
This approach ensures that the majority of processing occurs at a lower cost, while still retaining the capability to handle complex issues with a more advanced model when needed.
May add complexity to the system architecture.
