Could be an edge case, but the ability to choose models for prompt templates based on which API key is used. ie. I have 3 keys (dev, staging and prod). In staging I want to use llama 8b to save money while in prod I want 70b. Right now I need to implement this logic in my backend, but I could see value for something like dynamic model choice based on X (not necessarily API key but could be anything like user ID or something like that?)
I mostly use templates, and this feature doesnt seem to be there for templates so I end up having to make the same templates with different models which is a bit of a pain
