I applied for GPT-4 API months ago and never acquired it. I’m a ChatGPT4 plus subscriber and paying 20$ a month for it. How do I get GPT4 api in playground?
If you applied for GPT-4 but never got it you would need to prepay $0.50 as API credits according to How can I access GPT-4? | OpenAI Help Center.
Note that ChatGPT and the API are different things and are each paid separately.
