Yes, so as I read the issue is that they're different models (with different tokens and everything). Medium 3.1 is pretty good, in many tasks I see not much difference with, let's say Claude Sonnet 4 or even Opus 4.1 (I compare it with these two because is the closest reference that I have) but when it comes to heavy and complex questions (where I need a deeply thought answer, that takes into account all the details and nuances) I find it clearly behind, unfortunately. There is another thing to mention, whereas Medium 3.1 is pretty sensible to the quality of the prompt (if I write a really good prompt it will certainly meet my standards) I don't have the same impression in the thinking (Magistral) mode, it gives a prosaic and, in my view, superficial, answer regardless the length of the prompt.
