As I am not an expert on every current Discourse AI setting, this is my best understanding.
On both my site and yours, the setting shows:
Default LLM model: CDCK Hosted LLM
From what I can find, this is Discourse’s hosted LLM service. More precisely, the current CDCK/MoM implementation is a Mixture of Models routing layer rather than one fixed model. It can route requests to different open-weight models depending on the task. Discourse has a useful explanation here:
Another useful place to check is:
/admin/plugins/discourse-ai/ai-llms
That is the Discourse AI LLM configuration page, where administrators can see the configured LLM connections and which models are available for Discourse AI features.
For example, on the site I am an admin I see:
which will indicate if that is backing the action you used.
That appears to answer the question I asked about model and settings.
