Discourse AI - Missing settings after update = can't delete my old LLM

Hello,
We just updated discourse after several month without touching it.
We are pleased to see that a lot of work has been put in the AI but I think we are missing something to configure it.
I added the GPT-4.1 and 4.1-mini models to replace our 4o model, but when deleting it, I get this message :
An error has occurred: We were unable to delete this model because it is currently in use by ai_helper_model and ai_summarization_model. Please update the settings and try again.
Both ai_helper_model and ai_summarization_model aren’t existing anymore.

The other problem that I see is that because of that I don’t know how we are supposed to choose the LLM used for AI helper for exemple. I see that selecting a prefered LLM model for all personas has helped move some of the labels like summarize from 4o to 4-mini, but AI Helper label is still on 4o for exemple, and if my memory is good we were indeed selecting which llm is used for what independently from personas before ?

Thanks for your time

I have this fixed per:

And

We hid the settings but I think it was a bit premature cause it can get very tedious to set the helper setting across a wide amount of models, plus it can be very unclear why you can not delete an LLM.

@Roman will have a look at this and decide if this approach makes sense or not.

The alternative here is to have some shortcut that sets default_llm across multiple personas, and to completely remove all reference to the settings

Yes, it was probably a bit premature. I think it’s correct to restore these settings while we transition to a simpler way of configuring stuff through the features page.

We just merged a feature that lets you pick default llm globally. Can you try it out and see that you can delete your old LLMs?
