Which model does Demo use?

Please look at the attached images. These are answers to “What is a loop in Python” on the different models. I am looking for the model used on the Demo website (https://chat.openai.com/). How can I choose the same model on the playground and ChatGPT API?

Answer of https://chat.openai.com/.

Answer of Playground (code-davinci-002)

A loop is a sequence of instructions that iterates based on specified boundaries. Python has two primitive loop commands: while loops; for loops; The while Loop. With the while loop we can execute a set of statements as long as a condition is true.

I’m not an expert, but the demo you referenced is the most recent version, called ChatGPT. It is not available through the API (yet).

@jgvergo is correct in that the ChatGPT is not available as an API endpoint at this time…

It might seem a stupid question, but I think that’s the right place to ask. First I used the API Chat and didn’t know about the free GPT everyone uses. Then I tried the GPT one and found a huge difference between them. I see some good sides of the GPT but for my non-coding prompts API worked actually better. So I am curious are they a different model and is the GPT one the newer one?

ChatGPT is (we think) a fine-tuned version of GPT-3.5 (ie text-davinci-003)…

There’s also the original version of Davinci that’s still available - a lot cheaper, I might add.

Not a stupid question. They’re how we learn. Hope this helps explain it a little.

Yes, thank you! I was just curious why ChatGPT actually doesn’t impress me as the API does. GPT-3.5 has bit more restrictions in the text length for me, but it talks more human-like and more pleasant with some really good advices while ChatGPT talks with longer formal sentences and cuts its phrases all the time. Maybe it is more for coding, I don’t know, but it made me doubt if ChatGPT really the better one.
