Cursor Router
This release brings significant enhancements to routing intelligence and user control. New explicit optimization modes, "Cost," "Balance," and "Intelligence," now provide tailored performance options, from token-optimized quality to frontier-level intelligence. Underlying improvements include per-request classification for smarter routing decisions. Administrators benefit from robust new controls, allowing granular enablement, mode restrictions, and model management per team and group. Additionally, soft and hard enforcement options for Auto mode standardization and Grok 4.5 integration ensure more price-efficient routing.
