Which is cheaper: more Fast Requests or add own GPT-4 Turbo api-key?

I’ve answered this question here before:

Account sharing when working on the same project with another person

Logically, yes, if not simultaneously. You can use your API key even on the free plan. However, from experience, if you don’t code much and your projects are small, the API key should suffice. Otherwise, it might cost you more than the PRO plan, since it gives you 500 fast and unlimited slow requests.
