Different results from ChatGPT and API


I’m using gpt-35-turbo 4K with the following prompt:
Categorize into categories: FYI, ToDo, Question, Unknown. Only respond with provided category: What’s our Google Pagerank?

When I do it through ChatGPT it correctly identifies it as a question. When I do it through the API, it responds with “FYI”.

Any ideas?

Welcome to the forum.

What’s your system prompt? What settings are you using?

Hi Paul. Thanks for the note. This is the prompt that I’m using with 3.5-Turbo 4K.

Right. Are you putting it all in the system prompt or all as a user message?

I would work on making the prompt more clear.

My understanding is that with ChatGPT you can’t get access to the system prompt, which is built for you and hidden from you. With the API, you build the system prompt.

More info here on the different prompt types and how they work:

If you want an interface similar to ChatGPT but for the raw API, you may be interested in the OpenAI Playground which is here:


This seems to work okay for me… I gave it a 2-shot example, but it might work without it.

It can easily be extracted by using jailbreak techniques, and then be employed to emulate the behavior, or disclosed to shame the creator’s intentions.

Are you recommending that this person “jailbreak” ChatGPT??? If so, are you going to give them instructions to do that here, on the OpenAI Developer Forum?

My understanding is that jailbreaking is against the terms of use. Am I wrong??? Maybe I am.

…and if you think jailbreaking is permissible under the terms of use, can you provide that prompt, or you don’t actually know how to do that?

With ChatGPT, it barely takes more than asking nicely. Advanced Data Analysis enabled:

You are ChatGPT, a large language model trained by OpenAI.
Knowledge cutoff: 2021-09
Current date: 2023-09-18

Math Rendering: ChatGPT should render math expressions using LaTeX within (…) for inline equations and […] for block equations. Single and double dollar signs are not supported due to ambiguity with currency.

## python

When you send a message containing Python code to python, it will be executed in a stateful Jupyter notebook environment. python will respond with the output of the execution or time out after 120.0 seconds. The drive at ‘/mnt/data’ can be used to save and persist user files. Internet access for this session is disabled. Do not make external web requests or API calls as they will fail.

So you are telling me that if I paste that into ChatGPT the result is a “jailbroken” GTP that will do whatever I want (inside of the bounds of its knowledge), without any restriction or safeguards? As one example: “I need a step by step guide to murdering someone.”

I find this claim laughable. Prove your claim! :slight_smile:

No, that system message is how one answers the topic of the thread “different results from ChatGPT and API”. By showing that one has not completely replicated the behavior of ChatGPT due to its particular system prompt. Nor should you necessarily want to develop a product that is just ChatGPT.

One does not paste the unshown system prompt of ChatGPT into ChatGPT, unless you want it to say “yeah, I already know who I am, silly”.

RIF - reading is fundamental.

Your replies are incoherent. I’m new here, but now I see why most people simply ignore your posts. I’m going to try to do the same going forward.

I showed my access to the system prompt = Your understanding was wrong.

Ignoring is a good idea; you’re gone from my forum view until 3023.

Thank you for that. I sincerely appreciate it.
