This should answer your question: https://openai.com/blog/introducing-gpts

We’re rolling out custom versions of ChatGPT that you can create for a specific purpose—called GPTs. GPTs are a new way for anyone to create a tailored version of ChatGPT to be more helpful in their daily life, at specific tasks, at work, or at home—and then share that creation with others.

Starting today, you can create GPTs and share them publicly. Later this month, we’re launching the GPT Store, featuring creations by verified builders. Once in the store, GPTs become searchable and may climb the leaderboards. We will also spotlight the most useful and delightful GPTs we come across in categories like productivity, education, and “just for fun”. In the coming months, you’ll also be able to earn money based on how many people are using your GPT.

What's a version of a ChatGPT? A custom model? With custom pretraining, or just custom fine-tuning? Or just a custom prompt, lol.

I believe it is just GPT-4 with a custom system prompt added. You can also upload your own added knowledge base of data for the GPT to reference.

As TFA I linked to notes, "You can now create custom versions of ChatGPT that combine (1) instructions, (2) extra knowledge, and (3) any combination of skills" [numbers and italics added].

Regarding skills, "In addition to using our built-in capabilities, you can also define custom actions by making one or more APIs available to the GPT. Like plugins, actions allow GPTs to integrate external data or interact with the real-world. Connect GPTs to databases, plug them into emails, or make them your shopping assistant. For example, you could integrate a travel listings database, connect a user’s email inbox, or facilitate e-commerce orders."

So how does that work? Are they showing ads? (Narrator: its always ads) Is this the new ad-sense and search engine replacement? Its not SEO anymore, its custom GPTs.

It's probably a revenue share of the API usage fees that result from usage of the custom model.

[mattbrewsbytes]

That doesn’t track. I develop a custom model by paying them $x/month and they give me a discount based on usage? If somehow my new custom gpt goes viral and gets lots of usage I don’t see how that is connected with more money, if that is their intent. Its not really clear how this is a store or how money is changing hands here.

They're charging everyone using your model, per API call made.

They write you a check for X% of that resulting revenue.
