Other replies covered this, but I was basing that comment on the prices that commodity providers charge for GPU-accelerated VMs. E.g. the going rate for a NVIDIA B300 (288GB RAM) and the VM around it is somewhere between $5 and $20 an hour [1].
These providers have very little incentive to charge unprofitable prices (except maybe capturing more of the market, but there's not much lock-in here), so it's reasonable to assume somewhere in that spread is the "true" cost of being in this business, all expenses included.
[1] I'm using https://gpus.io as a reference here, and that's on-demand prices, which will tend to be the highest relative to other options.
(tongue mostly in cheek) sounds like I should be renting out these platforms and selling inference on them to OpenRouter
