Build cache size limit on Vercel increased to 5 GB

Vercel raised the build cache size limit to 5 GB on all build machines.

Before, a cache that went over the limit was discarded, so the next build started with nothing. The old caps were 1.5 GB on Basic and Standard machines, 3 GB on Enhanced, and 4.75 GB on Turbo. With 5 GB, projects with large dependency trees or heavy framework files can keep them saved between deployments, which can cut install and build times.

The change applies automatically to every build machine type at no extra charge, and there's nothing to configure.
