Cursor: Router Smartly Directs Requests to the Best-Fit Model and Becomes Default for the Teams Plan

What is Cursor Router, and how does it work?

Cursor Router is a new smart model-routing system within the AI coding tool Cursor. Instead of the user manually choosing a language model for every request, Router analyzes each query and automatically sends it to the most suitable model for that specific task. The frontier model, meaning the most advanced and expensive model available at a given moment, takes on demanding tasks such as complex refactoring or architectural decisions, while cheaper models like Grok 4.5 handle routine queries such as code formatting or simple edits.

Three modes: Intelligence, Balance, and Cost

Router operates in three modes that users or administrators can choose as needed. Intelligence mode directs requests exclusively to frontier models for maximum response quality, regardless of cost. Balance mode is designed for everyday use and mixes frontier and cheaper models depending on request complexity. Cost mode maximizes token efficiency, shifting as much traffic as possible to cheaper models like Grok 4.5, reducing cost at an acceptable drop in quality on simpler tasks.

Router becomes default for the Teams plan

Cursor has set Router as the default option for the Teams plan, its plan aimed at developer teams. Along with it come enterprise admin controls: team-level enablement of Router for the whole team, mode restrictions limiting available modes, and model allowlisting, meaning a list of models permitted for the team. These controls, and Router itself, are available on the desktop app, web, iOS, CLI (command line), and SDK, meaning administrators can standardize routing behavior regardless of which platform a developer uses. Unlike an approach where every developer manually picks a model for every request, centralized routing gives teams more predictable control over the balance of quality, speed, and cost in everyday work.
