Additional context

This is really cool. It would be interesting for future version of this concept to use sampling to shift some of the model and resource selection to the client, which could also make this more flexible to other types of models. The 'council of advisors' would still live in the server. (Of course, this would also be dependent on having a client that supports this type of interaction which there aren't many examples of yet!)
