I've added it with add custom provider and apart from a few hiccups with bing web search everything seems to be working. Am I mistaken? Or does this function just allow you to add models not yet implemented?

Works like a charm with a custom provider.

you can add it to openai api custom model list

[jakub-trzebiatowski]

But why can't it be added to the model list like all other models?

4.1 is currently in the preset list, I will add mini and nano to the list in next release, meanwhile you can add any model to the provider model list freely
