Mentioning that the default 3.5-turbo model will be pointing to 1106. So did OpenAI change the plans or the default 3.5-turbo is indeed the 1106 version?
The reason that the model alias pointers have not been updated is because there is a significant issue with functions and their encoding of UTF-8 in the previews, needing a new model to be trained.
Also a lot of pushback about the quality of these AI models. A switch would break many production apps that require useful output and not reduced instruction-following.
