Right now I automatically default to ChatGPT 4o, but I would prefer to stick to ChatGPT 3.5 for every new prompt unless I specifically switch to the newer model.

Would OAI be willing to add a switch to change the default behavior?

Please add this function. I feel like this was an option before. I am working on a voice command through shortcuts and siri to allow activating an audio conversation chat but will not work due to GPT4 being the default model.

Now we’re wishing we could default to 4…. @OpenAI_Support
