ChatGPT plus subscription and its purchased features is different than API, which has a separate billing system.
API gpt-4 is not available for accounts with only API free trial credits.
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.
If you are grandfathered in to a pay-as-you-go plan (monthly bill), then you won’t have access until:
- you make sufficient paid usage billings for your card on file to be charged (in the past $1+), and
- OpenAI uses that as a qualifying criteria when again adding more gpt-4 users.
- or OpenAI decides on a different gpt-4 onboarding policy for its long-term users.
