chatGPT plus and the OpenAI API are two different products, you can purchase one without the other, chatGPT plus is a subscription that gives you access to GPT-4 through the chat.openai.com website. The API is a “pay as you go” service that gives you access to a range of different models, an API call is a request made by one software system to another, you don’t need API access unless you’re trying to integrate OpenAI’s services into some other software.
Hope that helps
Hi you are talking about two different things. If you want the API you must go here OpenAI API sign up and make your organization can be a company or your name whatever you want. I’m not sure if they still offering credits but when I had my account I had credits to use but after that you have to pay by use. You can see the pricing on OpenAI printing each model has a different price I think Ada is the cheapest one but doesn’t have the Davinci power.
