Why are chatgpt devs ruining the UI this much?

I’m not happy with being forced to use GPT-4o. I mainly use ChatGPT for coding stuff, and GPT-3.5 is way better for that because of the long output and “continue” button and unlimited. GPT-4o is too limited, so it’s kind of unhelpful.

What I need is a clean UI… It would be awesome if you could add a simple button at the sidebar, to choose between the models.

A lot of users would be happy to keep using ChatGPT if we could just pick the model that works best for us. I wonder, why should the devs start messing things up when the competition is stiff?

Gemini is doing stable and offers almost everything for free. Chatgpt devs have no time to mess up.
