Is GPT-4 available when you have api-key which can use gpt-4?

[DahaeKimEsther]

Whenever I'm trying to use model: gpt-4

it returns the message below {"message":"The model: gpt-4 does not exist"}

Currently, only text-davinci-003 model is supported. The project has plans to integrate more open-source LLMs in the future. Nothing is mentioned about API integration for closed-source LLMs. As for now, it isn't possible to use GPT-4.
