The confusion in terms called out here (and even demonstrated) is probably not to OpenAI's benefit and I am surprised they haven't spent more effort in trying to correct that. ChatGPT is a website that lets you do chat completion [1] against LLM models, and it exposes some extra functions like plug-ins if you are lucky enough to be white listed for them. GPT 3.5 and GPT 4 are the actual models. Someone telling you that they did something cool with ChatGPT probably means GPT 3.5 [1]: https://platform.openai.com/docs/api-reference/chat https://platform.openai.com/docs/api-reference/chat

> Someone telling you that they did something cool with ChatGPT probably means GPT 3. The confusion is that ChatGPT is using GPT-3.5 by default, but if you pay the $20/month subscription price, you can switch it over to GPT-4 (with query limits). Usually, when someone is telling you they did something really cool with ChatGPT, they're actually using GPT-4. An extra layer of confusion is the API access: GPT-3.5-turbo and GPT-4 models are both optimized to be used in chat, which is somewhat different than earlier text completion models. Because of it, people using GPT-3.5 or GPT-4 via API access (possibly with one of the "alternative ChatGPT frontends"), will often also say they're using "ChatGPT". This is almost, but not completely accurate - the actual ChatGPT contains a bunch of hidden "features" (hidden prompt, extra moderation), that are mostly detrimental to the output/experience you get.

  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.

Similarily, reminds me of "bitcoin" the currency and "Bitcoin" the protocol.

ChatGPT is more than an interface, the models it uses have gone through additional training and modifications. > Someone telling you that they did something cool with ChatGPT probably means GPT 3. This seems like an incorrect assumption. 3 is very old at this point, 3.5 is free and the best demos are based on 4 which is a huge improvement compared to the previous versions.

  Have they? Querying 3.5 through the completion API does not return meaningfully different results than doing it through the website. Aside from the extra functions like plug-ins that most of us can't use yet, the main difference appears to be everything on the website is forced through the moderation API as well. Typo fixed.
