Consider using the ai module for AI backends.

First off: I love the functionality.
It looks very simple (in a good way) easy to use and nice.

Ai under the hood

If you switch to the AI module under the hood. If you would do that you'd support google, openai , azure., ...
Because the Ai module makes that abstraction for you.
If you add the AI module under the hood, I'll also link to your module on our project page. As I really like your implementation.
