Model Tiering
An AI deployment architecture practice that assigns tasks to models of different capability levels based on task complexity. A routing layer automatically matches requests to the appropriate model tier, reducing overall inference costs while maintaining output quality.
Timeline (last 90 days)
For Agents where decisions account for more than 80% of a task, moving decisions to a dedicated small model can bring order-of-magnitude cost reductions; but if the task is mainly long-text generation or complex code reasoning, the savings ratio narrows significantly.
The layered architecture introduces coordination costs for switching between models: falling back to the main model requires reorganizing the context, which may offset some of the latency gains.
The model tiering strategy recommends using a powerful mid-tier model for creativity-heavy tasks such as drafting, and using cheaper, faster models for lightweight tasks such as titles, summaries, and hashtags.
Model Tiering is a common architectural practice for achieving on-demand matching, dividing tasks into several levels by complexity, with small local models or rule engines at the bottom layer, medium-scale models in the middle layer, and flagship large models called at the top layer.
In actual deployment, enterprises often find that more than 60% of production requests can be handled at lower tiers, thereby reducing overall inference costs.
