ChatGPT is not the same thing as the underlying model. ChatGPT is just a UI over the model. The tweet was about the model.

ChatGPT is also the fine tuning and prompting of the model. It’s a distinct set of weights from “raw” GPT-4/etc, it’s just not a foundational model.

No, ChatGPT isn't a model. gpt-4 is a model, gpt-3.5-turbo is a model, text-davinci-003 is a model. ChatGPT is a user interface.

It has a very basic prompt on top of the existing models. There is no additional fine tuning involved.
