Okay fine, I'll run the numbers... There is indeed a substantial price premium for this platform:

1 vCPU /hr on Cloud Run clocks in at $0.0864/hr compared to $0.0331/hr on VMs with custom CPU or $0.0316/hr for predefined.

1 GB /hr on Cloud Run is $0.009 compared to $0.00094 for Custom RAM or $0.00089 for predefined.

I can assume you can also forget about sustained use discounts.

I would imagine the costs of resources to deliver hot-start performance is significant, but this makes the case for the service a lot weaker, especially for long-running jobs that could just be tossed on a preemptible VM for dramatically cheaper rates.
