This is what we've done at Salad (www.salad.com). SaladCloud (officially launching on July 11th) has 10k+ Nvidia GPUs at the lowest prices in the market. Not conducive for training but for serving inferences at massive scale.
For example. An '8 core/16GB RAM/3080 Ti 12GB' is 50% more expensive on salad than on Vast.
In fact, I can get more than double the resources for the same cost as Salad in the form of a '28core/32GB RAM/2x3080 Ti 12GB' on Vast.
So, what is your differentiation? Why would I ever use Salad?
