When I go to the chat window in the API area, it shows that I’m using GPT-3.5. I want to use a commercial chatbot that requires me to plug in my API key so I incur the usage costs. They’ve told me that the chatbot will use whatever GPT model is my default in OpenAI. Is it possible to set a default in OpenAI and if so, how?
I would not trust these people that want your API key and also give nonsense advise.
The OpenAI API is for developers that create their own products, not oriented to consumers.
The API is accessed by code, and part of every request you make with that program code involves setting the model and the parameters that you require. The “API Playground” is just a demonstrator of features.
An author of software would know this and the software would have to select the AI model to make direct communication with OpenAI.
The API key that you use to pay for services is like a bank account password, and should never be shared - or put into untrustworthy software.
