Correcting the correction of a correction: The chat interface is no longer using GPT-3.5, since May 3rd. What is the default model called? I have no idea. The release notes page [1] calls it ChatGPT model, the bottom of chat interface calls it "ChatGPT May 3 version".

Also people usually call out when they use GPT-4, but in the end you can only assume and be wrong 50% of time.

For whatever it's worth, playing with the model selector gives you a parameter in the URL.

The default model is "text-davinci-002-render-sha"

The legacy one is "text-davinci-002-render-paid"

GPT-4 is just "GPT-4"

One other useful tell if someone is showing you a screenshot of chatGPT is that GPT-4 uses a black logo avatar, where 3.5 uses a green one.


Wait, isn't the default model of ChatGPT called "gpt-3.5-turbo"? IIRC "text-davinci-002" is the old one.
