(I'm not the author) The easiest way to charge for this kind of software is to make it SaaS, and I think that's pretty gross, especially for a CLI tool.

It doesn't have to be one or the other: you could sell the software under libre[1] terms, for example.

Agreed that SaaS feels ugly. Agreed on selling it as libre. The only thing I could imagine charging for in a subscribed model would be for services that are hosted (e.g. instance/gpu provisioning/monitoring/maintenance in the cloud) while also offering the ability to self-host the same machinery.
