From the docs:
On June 13, 2023, we announced new chat model versions in the Function calling and other API updates blog post. The three original versions will be retired in June 2024 at the earliest. As of 01/10/2024, only existing users of this model will be able to continue using this model.
Does this mean the gpt-3.5-turbo-0301 model will possibly be available after October 2024? And how are “existing users” defined?
