I'm hosting the machines so that users don't have to set anything up on the cloud side. It could have on prem or open source versions if people are interested in setting up their own clusters.

So what machines can I choose from? Like, if I need a 24 GB GPU, will you have one? And what’s the pricing? Where do I find that info?

So far I'm implemented pretty coarse-grained control over machine specs: it's $20/month for a MacBook-like machine and $3/hour if you want to use "a GPU" (whatever Amazon has available for cheap). I figured the config could specify exact disk/ram/instance type requirements in the future, it sounds like something you're interested in?
