Vercel announced that turbo build machines can now be enabled for a single deployment by running vc deploy --turbo. One such build receives 30 vCPUs and 60 GB of memory, and the project's build machine settings remain unchanged.
This lets teams give one heavy or failing build more resources, such as while investigating an out-of-memory error, without changing the default for every deployment. The post does not state pricing for per-deployment turbo builds or how much faster typical builds complete.
