I rebuilt a Jev-style classifier on Qwen3.5-4B: shared-prefix tree, open weights, fine-tunable, ~140 ms on one H100

By now everyone has heard of Jev: fast, accurate answers to multiple-choice questions about any text, in one API call. Here's how to get the same thing on your own GPU. SelfJev is a 4B model (Qwen3.5-4B + LoRA) that works like Jev: ⚡ About 140 ms per call on one H100, which is about as fast as Jev'…
