People are always talking about spot pricing when GPU compute comes up which is valid but not for the ML use-case (which this article is discussing). Spot is 100% incompatible with ML training. You need to be guaranteed that your many hour/multiple day job is going to complete which is antithetical to spot. At Paperspace, our goal is to provide a steady state low price that you can depend on because our primary audience is ML. Spot would be more ideal from an efficiency perspective but it’s just not viable in this context.
