There's a gap between Anthropic's Artifacts and OpenAI's GPTs.

Anthropic Artifacts makes it super simple to create a little sandboxed live demo app with whatever UX you want that you can share with anyone you want.

But the Artifact you distribute can't run additional LLM calls on the viewer's behalf.

LLM calls are the secret ingredient for magical mini-apps!

OpenAI's GPTs allow setting a custom prompt and script for an LLM chatbot, allowing magical answers to users constrained by the author's guardrails.

The fact the viewer pays for the LLM calls means the author doesn't worry about going bankrupt from sharing the thing they made.

But you can't do any structured UX other than chat.

What if you could have a magical mini-app that could be loaded by anyone with the link, that could do LLM-powered magic using paid for by the viewer?
