1. GitBook Case Study Pegs AI Crawlers at 41% of Documentation Traffic

Vercel. A Vercel-published case study with GitBook reports that AI crawlers now generate 41% of traffic to the 30,000 documentation sites GitBook hosts on Vercel, up roughly 5x year-over-year. The platform processes about 40,000 cache invalidations a day in under 300ms using tag-based invalidation, with combined human and AI-bot load served almost entirely from cache. The data point is a useful reference for any team sizing infrastructure for documentation, where assumptions about user-mix have shifted faster than most capacity plans. Source
