The option + space shortcut for ChatGPT MacOs app doesn’t allow to choose a model, neither it shows which one is currently chosen. That made me waste some o1-preview usages on quick, trivial queries.
Frankly, this way, you never know which model will answer your prompt. (Especially if you have a parallel conversation going on in the main App window).
Easy fix would be to include a model picker into the quick launcher.
