Will it be free to create GPTs for the "GPT App Store"?

I think they are expecting that most of the GPTs will be free given they made the tools that anyone can use to create them for free without billing mechanics. Given that these GPTs will be accessible only behind a paywall, then that at least gives them the ability to share in that revenue. You see all of these people saying “Look what I created! Here is a link” but you need to be a paying subscriber to access it. I don’t think they plan to share any revenue generated from the API. That’s for developers to access and monetize their own apps outside of ChatGPT. The GPTs are solely intended to get people subscripted to GPT Plus.
