That's flat wrong. That is ChatGPT's answer to the difference between ChatGPT and gpt3. ChatGPT does not really know about itself, its data cutoff is from 2021.

ChatGPT is trained on a variant of gpt-3.5 (instructgpt), read more here https://openai.com/blog/chatgpt/

Okay, maybe I'm wrong, but the article doesn't explain how ChatGPT compares to GPT-3.

ChatGPT uses the model text-davinci-003, which was released alongside it. The previous model of the same kind was text-davinci-002, and in a comparison I read, seems to perform much less impressively. So it's not just the chat interface. It's genuinely more impressive in my opinion.

Ah that's weird. Using text-davinci-003 in the playground gives very different answers to ChatGPT, and that's with playing with the temperature as well.
