## Summary

Guillermo Rauch argues stateless sandboxes are the wrong benchmark because agents need their identity, skills, repos, and memories with them. He says the Vercel Sandbox team is meeting its latency and throughput targets while expanding to 19 global regions. The linked Vercel changelog reports Sandboxes with Drives start 2.4x faster, with median creation falling from 1.7s to 0.7s.

Vercel Sandbox team has been beautifully delivering on their latency & throughput SLOs, while prioritizing reliability and security.

Doing this while shipping clusters in 19 (‼️) global regions, new features every week, and under immense amount of customer demand in the double digit growth percentage per week.
