You are assuming the operator of vibe coding tools is not experienced in the domain.
There's more to than just the website. You have network bandwidth costs, security costs, infrastructure costs.
You can't just spin up a VPS and throw a few brain jar's in; the network bandwidth must be a fortune. Hosting over 700GB+ for many of the same models has storage cost too.
That is fair point, but still you can build such system for under a grand and then pimp yourself out to VCs.
