Cursor Launches Cursor Router: A Request Classifier to Cut AI Costs Up to 50% Without Quality Loss
Cursor has released Cursor Router, a classifier that inspects each request before model execution and routes it to the best-suited model. In online A/B tests, the system achieves frontier-quality output at 60% cost savings, with early enterprise accounts reporting 30–50% savings versus Opus 4.8. The router is trained on 600k+ live requests and considers cache-miss costs in its savings calculations.
