Qwen3.5 4B + grabbing logits is almost "Jev"? Or even just Qwen Reranker?

Saw the new Introducing System One Models & Jev - TypeSafe AI Blog Jev model which just outputs probabilities given choices and I thought it sounded a something the Qwen reranker models could do? Then I tried implementing it and got even better results with Qwen 4B + just assign each option to a letter and grab the logit probailities for each one.
