2. The system of claim 1 , the operations further comprising: determining an output type for predictive output for the client-subscriber computing system comprising: determining from the information that describes each of the trained predictive models that one or more models included in the predictive model repository are compatible with one or more input types determined from the request to input types and that the one or more models can generate output of one or more output types, and selecting the output type from the one or more output types.
