I installed my api key but it only show chatgpt 3 , is it because my account is personal ? to make chat gpt 4 works i need to switch to Business profile ?
ChatGPT plus subscription and its purchased features is different than API, which has a separate billing system.
API gpt-4 is not available for API free trial credit users. If you’ve never put in a payment method before, you can purchase a minimum $5 paid credit, and that will give additional models and lift the rate limit per minute, while you still first use the trial credits.
