## The brief

Vercel will end collection of First Input Delay measurements in Speed Insights on November 1. Its responsiveness scoring already relies on Interaction to Next Paint, which replaced FID as a Core Web Vital. Vercel says customers need no configuration changes: existing FID history remains viewable, and the switch will not alter their Real Experience Score.
