In Direct chat mode in Assistant, it would be helpful to be able to change the amount of "creativity" the model has. "Creativity" would be an abstraction for optimal temperatures. For example, "Minimal" or "Deterministic" level would be a temperature of 0.3, "Normal" would be 0.5 or 0.7, "Maximum" would be 1.0 or higher (although in my experience, GPT-4 becomes psychotic above 1.0).
Raycast AI has implemented this using a dropdown with similar naming.
