I still don't get the point of jev....it's basically an optimized models/runner on really short context and output?

It's a specialized classifier model. It classifies input text into categories with a confidence score. Usually those classifiers are small like in the OP but jev is supposedly big, smart, and fast enough to play DOOM by having the scene described in text and classifying it into button presses.

		Well the Doom demo is again passing a textual structure....I am not really convinced on how it's different than any other llm that execute small context within 100ms. On a MBP M3Max with LFM 2.5B, I get about 500ms -600ms on "source_text": "Invoice #4471 issued March 3, 2026 to Beaver Dam Logistics for $12,840.00, net 30." with a 4 property structure output https://docs.typesafe.ai/primitives/advanced I can't test it on a better model / my main workstation, but sub 1sec for short prompts is not impressive? I am sure that we can get something like 100ms-300ms with a Qwen 3.8 27b model for a similar query on a 5090 class GPU. edit: 203ms wall clock on a somewhat busy workstation with https://huggingface.co/LilaRest/gemma-4-31B-it-NVFP4-turbo
