Vercel Sandbox storage is now 64 GB: size agent workspaces for large repos

UpdatedSeptember 15, 2026

Vercel Sandbox storage is now 64 GB per sandbox, up from 32 GB. If you run coding agents, long tool loops, or OpenAI Agents sessions on Vercel, that change is not a changelog footnote — it changes how you size repositories, dependency caches, and disk-spilling workloads inside an isolated session.

The upgrade applies to sandboxes created from a Vercel Managed Image or a custom image, and to sandboxes still configured with the deprecated runtime property. Primary source: the 11 September 2026 Vercel changelog entry.
