GPT-3.5 was revolutionary. It collected many users within a short time. Some five months later, GPT-4 was launched (say in March, 2023). It is now time to have a new version of GPT, but OpenAI has just introduced Code Interpreter now. It is a very useful feature, but indicates the company is just adding incremental features. Or is it that the company has already introduced GPT-4.5 with code Interpreter, without officially declaring so. This is just speculation, nothing official so far. Some say that the next version would be super intelligent AI. Altman expected the journey to superintelligence to be of four years.
