I disagree. From the average user perspective, it's quite confusing to see half a dozen models to choose from in the UI. In an ideal world, ChatGPT would just abstract away the decision. So I don't need to be an expert in the relatively minor differences between each model to have a good experience.

Vs in the API, I want to have very strict versioning of the models I'm using. And so letting me run by own evals and pick the model that works best.
