New Vercel projects now run on Fluid compute by default.

This update follows Fluid’s general availability, its adoption across large-scale production apps, and all v0.dev deployments shipping with Fluid enabled by default.

Fluid compute reuses existing instances before spawning new ones, cutting costs by up to 85% for high-concurrency workloads. It combines the efficiency of servers with the flexibility of serverless:

• Concurrent requests per function

• Scale from zero to infinity

• Minimal cold starts

• Usage-based, pay as you go

• Full Node.js and Python support

• No infrastructure to manage

• Background tasks with waitUntil
