I believe mistral just released Mistral Small 3.1, I can't wait to try it out.
There is also a reasoning variant from Nous Research which I've recently got up and running.
Mistral's model is in a class of their own. I'm inclined to try out their larger models via API. I wish they had a reranking model as well.
