Elastic Build Machines now protect against out of memory builds
Vercel has updated its elastic build machines to protect against out-of-memory (OOM) build failures. The system monitors build memory usage and automatically adjusts machine tiers. Thresholds are set conservatively to balance reliability and cost, considering only the build's own memory usage, not Vercel's infrastructure. Key behaviors: memory-intensive builds are no longer downgraded; builds near OOM are upgraded automatically; and if a build fails due to OOM, the next deployment runs on a higher tier. This feature is available for projects with elastic builds enabled in team or project settings. The change aims to improve deployment reliability without manual intervention.
Reduces build failures and manual tier adjustments for memory-intensive deployments.
