Feature Request: add precise/balanced/creative toggle button

Instead each model have its own config temperature, add option to set temperature/top-p etc by selecting precise/balanced/creative toggle button.
It would be great because there is no single temperature that can fit all usecases.

I think it be be great that this can be enabled/disables using the .env by using new field "CREATIVENESS_TOGGLE_ENABLED=false/true" or it would be configured under the models section by adding "CREATIVENESS": {"precise": {"top-p":0.2," temp":0.1}, "balaned: ....}

Thanks ahead
