Interestingly, ChatGPT has no idea if it's running GPT-3 or GPT-4, since it has no concept of GPT-4 existing in September 2021 (its knowledge cutoff).
Me: Are you running on GPT-3 or GPT-4?
ChatGPT: As of my knowledge cutoff in September 2021, the most advanced version of GPT (Generative Pre-trained Transformer) publicly available was GPT-3, which is the version I am based on. At the time, GPT-3 was the largest and most powerful language model created by OpenAI, with 175 billion parameters.
I am not aware of any public announcement or release of GPT-4 by OpenAI since then, but it is possible that they may have continued to work on new versions of the model in the meantime. However, I have not received any updates on my own capabilities beyond my knowledge cutoff date, so I cannot currently provide information beyond that point.
Unless you are using the paid version (ChatGPT Plus), then you are certainly still talking to the GPT-3 model. Even on ChatGPT Plus, my understanding is that you have to specifically select the new model.
