I am using Open AI API for gpt 3.5

Hi Guys
I hope you are doing good.

I have an issue with the Open AI billing system, I am using it’s API for gpt 3.5 but I am charged for GPT - 4. Anybody else have this issue?

Could you please guide me how to overcome this issue? and secure api key from misuse?


Please see this help topic


If you are not using GPT-4 but you are being charged for it then your API is being used by someone else, you should revoke your key and then check that your API key is secure and also make sure that your key is not included in any application you have built.
