Anyone getting GPT-3 responses when calling API for GPT-4 model?

Hi

I had been successfully receiving GPT-4 responses but the last few hours it seems i get GPT-3 even when i reqest a v4 model

Is this common? Anyone else having or had the same in the past

Tha ks

FYI

The way i can tell is, the conversation tone is significantly more robotic

But more… i ask it what model it is and it tells me GPT3

If you ask GPT4 it knows its GPT4

Sounds trivial i know, but the api is accepting and returning the model parameter indication v4 and i used to have v4 responses

But lately… its dropped back down to v3

Also worth noting… it “appears” im being charged for v4 ?!? (could be mistaken though)

You describe operator error and assumption.

You have to program gpt-4 or others to know what they are and their purpose to you.

Thanks for the response

Sorry though, but im not sure i agree

In your case what does it say if you dont give it context initialiser?

I.e. simply ask “what version GPT are you?”

For me it says something along the lines of “i am based on the GPT-3 architecture”

However, the chatGPT accessable through chat.openai.com more clearly seems to know it is a GPT-4 model

I understand that you can ask it to respond differently with the initializer, but it doesnt seem to be a necessary precursor

What am i misunderstanding please

It also doesnt “feel” like GPT4 (though obviously that isnt a particularly measurable quality - hence focusing in its response to the question)

They likely have the info in the system message. Are you aware of hallucinations in LLMs?

I am

I just wander why the API model is consistantly different to the chatGPT model in this minor regard

Do you get the same response to the question then?

Edit: rereading your response i now see what youre saying… the chatGPT has a system initialiser setting its context a little more precisely

As I mentioned, ChatGPT has a system prompt. For the API, you have to send your own system prompt.

Default chat gpt3.5 very low accuracy answer give. you return chat gpt-3 helpful🙂
