> GCP allows you to attach a GPU to an arbitrary VM as a hardware accelerator - you can separately configure quantity of the CPUs as needed.

That would seem to indicate that asking for a VM on GCP gets you a minimally configured VM on basic hardware, and then it gets migrated to something bigger if you ask for more resources. Is that correct?

That could make sense if, much of the time, users get a VM and spend a lot of time loading and initializing stuff, then migrate to bigger hardware to crunch.
