Yeah, and I think they are using an old version (3.0? 3.5?) of ChatGPT, not GPT4, which is way better. Can anyone verify? They confusingly list GPT4 as a separate LLM, even though ChatGPT supports GPT4.
No one using ChatGPT is confused. You have to make an explicit choice in the switch, and if you are using the API you have to put the name in as a parameter.
