Escalation Routing
Escalation routing is an LLM routing strategy that starts at a low-cost model tier and escalates step by step to higher-tier models when the inference budget is exceeded. It is characterized by very low decision cost and fail-safe behavior, since in the worst case the request still ultimately reaches a large model.

Escalation-Based Routing is an LLM routing strategy that starts from a low-cost tier and escalates level by level when the reasoning budget is exceeded.
The worst case of escalation-based routing is that a request ultimately lands on a large model, so it will never permanently fail to get a high-quality answer due to misclassification.
The decision cost of escalation-based routing is extremely low (only one lightweight judgment is needed), and it inherently has a "fail-safe" property.
The cost of escalation-based routing is that complex requests may incur the latency overhead of two inferences, so latency budget estimates need to leave margin.
