Managing consumable AI costs

Thanks for this plugin which looks awesome.
Is it possible to use some of these AI features for free? Otherwise how to control the cost please? Is there a way to give access to AI features only to selected people (cherry picking) ? How can I re-invoice them for the cost? Have you a solution to share ?

Cloudflare and Google Gemini both have a generous free tier. Both can help you get free Related Topics, and Google Gemini can be used for almost every other feature too.

Yes all features have group based access control.

Groups in Discourse can be pay-to-join via plugins, like Discourse Patreon and Discourse Subscriptions.
