ChatGPT can be used in two ways: through the OpenAI API or with ChatGPT Plus subscription.
OpenAI API Usage:
1. You first need to sign up for access to the GPT-3 API by OpenAI.
1. Once you’ve signed up and received access, you need to set up your development environment to be able to send POST requests to ‘https://api.openai.com/v1/engines/davinci-codex/completions’.
1. Next, send a POST request to this endpoint using your API key for authentication and including your prompt in the request payload.
1. Analyze the response from the API call and use it as you need in your application.
ChatGPT Plus Usage:
1. ChatGPT Plus is a subscription plan that gives you general access to ChatGPT, faster response times, and priority access to new features and improvements for $20/month.
1. You need to visit chat.openai.com and follow the steps for the subscription.
Remember, usage with the API is charged separately and is not included in the ChatGPT Plus subscription.
Make sure to read and understand the OpenAI’s use-case policy before implementing it in applications, as certain uses are not allowed.
