Limit the number of AI tokens a user can use in a day?

I’m going to assign this configuration to an intern next Wednesday on a self-hosted Discourse site. Do I need to tell them to pull from a main branch on GitHub? Or, if they add this line in app.yml, is it sufficient?

hooks:
  after_code:
    - exec:
        cd: $home/plugins
        cmd:
          - git clone https://github.com/discourse/docker_manager.git
          ...
          ...
          - git clone https://github.com/discourse/discourse-ai.git 

I want to allow the Discourse AI plugin features to only registered users. Is that the default behavior?

It doesn’t look to me that the AI-enhanced search has per-group control???

For the AI bot, I’m thinking of setting it to trust 0 and setting a limit on tokens per group, increasing as the trust grows. Is this a good strategy?
