Billing and cost
Is it cheaper to run fewer, larger runners?
Quick answer
Only if your workload actually parallelises. Otherwise you pay more per minute for cores that sit idle.
The detail that matters
Look at CPU utilization per job. If a 16 vCPU runner averages 20% utilization, you are paying for 13 idle cores.
Your next build could be twice as fast, at half the price
