Minor Enhancement Request: Would be nice to add a model_name or alias attribute to model config

Currently there are some 3rd model api vendor like azure or ark will use unique model id as model name such as "ep-20251234170943-abcde", while from usage point of view, still be quite useful to display real model name in some way, suggest that either we can add an additional launch flag and application config such as model_name or model_alias to be used in the console display
