Using cheaper language models for AI agent tasks can lead to unexpected costs due to increased retries and failures. While cheaper models might seem economical per token, they often result in higher overall expenses when considering the cost of completing a task successfully. The author suggests that instead of solely focusing on the cheapest model, developers should strategically route tasks to different models based on their complexity and safety requirements, leveraging cheaper models for simpler sub-tasks and more capable models for critical planning and recovery.
