Makes sense that this would be less beginner friendly so maybe you're correct that this is a P2 feature.
I guess I was thinking more in terms of pricing models and scaling up a service which is obviously a complicated decision for a startup so I'm not really sure what makes sense here. My rationale for wanting to buy/rent the model is that as a service scales it becomes increasingly important to own the model and the hosting. One of my concerns with building on top of a service like this is that it will potentially reach a chokepoint in the future. In general training a model is expensive and unique but hosting it is a commodity service. This will incentivize customers to use the service when they are small and then drop it when they grow to a certain size which is not necessarily ideal for either party.
