How Cursor Router Chooses the Right Model for the Task
Anysphere, Thursday, August 6th, 2026
Cursor Research explains how Cursor Router picks the right model using a complexity predictor and task taxonomy.
Cursor Research has explained the internals of Cursor Router, which automatically sends each request to the most appropriate model.
The system combines a Compass complexity predictor that scores a task from 0 to 1 with a task taxonomy router.
The taxonomy classifies work by domain, task type, and modifiers such as visual content. Together these signals determine which model handles a given request without the user choosing manually.
