I often chat with the various bots at Poe.com. We see bots such as:
- ChatGPT: Powered by gpt-3.5-turbo.
- GPT-4: OpenAI's most powerful model. Stronger than ChatGPT in quantitative questions (math and physics), creative writing, and many other challenging tasks. Availability is currently limited.
So it seems "GPT" and "ChatGPT" are not synonymous. Elena Alston summarized it as:
ChatGPT is an app; GPT is the brain behind that app
This somewhat makes sense, but ChatGPT and GPT-4 have the same interface at Poe.com, so this makes me think "GPT" and "GPT-4" are not different versions of the same thing too. And then there's GPT-3.5-turbo, which presumably is a variant of GPT-3.5. The more I think about it, the more confused I get.
Question: What's the difference between the terms "ChatGPT", "GPT", and "GPT-4", and "GPT3.5-turbo"?
