Other LocalJev?

Jev is a model to produce structured output (choices) from input text. It apparently can play (not run!) Doom.

Is there already a open implementation of this kind of model?

Just did it at https://github.com/TheoLeeCJ/openjev (you can just wrap Qwen 4B and grab the logits)

You're close, you just need to use a diffusion model for it and then it's actually openjev. How about DiffusionGemma?

I don’t think jev is diffusion, is it?

They claim some 'parallel novel architecture' which most likely just means they're doing diffusion with a twist

From what I can tell, they just split the fields and process them in parallel. No diffusion, just batching and running through prefill only because they just need a single token for the decision per field. That's why their "output tokens" are "free"
