Vercel announced that sub-second artifact deployments are now supported in the Vercel CLI. According to the post, developers and their coding agents can deploy static artifacts in less than one second with a command such as vercel deploy on a local folder with the prod flag.
For agents that generate reports or static sites, a fast deploy step shortens the loop between producing an artifact and sharing a live URL. The post does not state size or file-count limits, which artifacts qualify, or whether build steps are skipped, so those constraints need to be checked in Vercel's documentation.
