title: "Introducing Cursor Router"
description: "Cursor is launching Cursor Router, a model-routing system for Teams and Enterprise plans that automatically selects a model for each coding request to target frontier-quality results at lower cost. It classifies requests using query, context, task complexity, domain, and model behavior, trained on more than 600,000 live requests and optimized for user satisfaction (AFC); the classifier is cache-aware and designed for frequent model updates. In online A/B testing across millions of requests, the company reports frontier-quality performance at 60% savings, while early-access accounts saved 30%–50% versus routing all traffic at Opus 4.8 API rates without a quality decrease. Three modes—Intelligence, Balance, and Cost—let teams choose a cost-intelligence tradeoff, with administrators controlling defaults, availability, and allowed models across supported Cursor clients."

# Introducing Cursor Router

## Summary

Cursor is launching Cursor Router, a model-routing system for Teams and Enterprise plans that automatically selects a model for each coding request to target frontier-quality results at lower cost. It classifies requests using query, context, task complexity, domain, and model behavior, trained on more than 600,000 live requests and optimized for user satisfaction (AFC); the classifier is cache-aware and designed for frequent model updates. In online A/B testing across millions of requests, the company reports frontier-quality performance at 60% savings, while early-access accounts saved 30%–50% versus routing all traffic at Opus 4.8 API rates without a quality decrease. Three modes—Intelligence, Balance, and Cost—let teams choose a cost-intelligence tradeoff, with administrators controlling defaults, availability, and allowed models across supported Cursor clients.

## Context

Roughly 60% of developers using Cursor select a single model as their daily driver, causing routine work to be completed at frontier prices while AI spend grows faster than output quality.

## Approach / What changed

Cursor Router classifies each request before execution using its query, context, task complexity, domain, and model behavior, then routes it to a suitable model. It was trained on more than 600,000 live requests, optimized for user satisfaction (AFC), and designed to account for cache misses in routing decisions and evaluation.

## Takeaways

- Cursor Router’s online A/B test covered millions of live requests, and reported savings include the cost of cache misses caused by routing decisions.
- Auto Intelligence was reported to deliver about 60% lower cost than Fable on user satisfaction, while Auto Balance delivered about 36% lower cost than Opus 4.8.
- Admins can enable Cursor Router by team or group, restrict selectable modes, set defaults, and allow or block specific models.
