Model routing by task type: the savings math, the classifier overhead, and the A/B that proves it
Implementing task-type routing for LLMs can significantly reduce costs, potentially by 40-60%, without compromising quality. This approach categorizes tasks into simple, code, reasoning, and complex, directing each to the most cost-effective model tier. The overhead of the classifier is minimal, typically milliseconds, compared to the longer processing times of LLM calls. This strategy is particularly effective for workloads with a high proportion of simple tasks, where the price difference between small and frontier models is most pronounced. AI
