Great ! Especially for eg Codestral, and the new beautie in town Phi-4 too !

Looks great! Good to merge. The unit test could be using classes for mock, to allow for more reuse -- we can do it next time in the future. Same with unit test hitting the actual endpoint, we could have one that runs against a few different models.

I agree that the unit tests could be more standardised for models. I tried not to change too much but i will have a look at this later.
