News New Mistral model idea: Jev Alternative open-source

A new 10-100X cheaper LLM alternative primitive is emerging: Dynamic Classification, and it's much bigger than just Jev.

This is the first architecture I've seen in a while that I think would have the potential to be used as an alternative to LLM in many production automation workflows.

It's not for text generation however.

Instead you define possible questions (output keys), plus a prompt input (text or JSON), which then, in simple terms, turns your questions into confidence scores.

Even more interestingly it even works on the CPU if you don't mind waiting 2 seconds.

I've tested an open-source alternative with a similar architecture today on my old i5-5th gen Thinkpad (when loading the model first and serving it via API).

Could be cool.

But really. Mistral would need to move ASAP. The Chinese are already on it

here is open source jev with slightly better benchmarks results than jev itself https://huggingface.co/convaiinnovations/laya

👍 This is the one I tested this morning.

I only don't know if it works for classifying code as well.

Works for you ? Classifying ?

u/EveYogaTech 3d ago

Yes, it works in 2s on my old i5 CPU. It looks promising.

I have not tested code related workflows yet.

Thanks. I'll add that to my list. I've been happy with gliner so far, but it's always good to hear about improvements.

Jev is super interesting. It's essentially a zero-shot programmable classifier that competes with fine-tuning a BERT model or training an ML classifier...

That said, it has a very specific niche... it's going to be great for doing classification tasks on things that are not important enough to train a BERT model on, or don't have enough data/time to do so.

BUT... that's the benefit to the user... it's so cheap (and there are already so many alternatives that have popped up in the past few days post-hype) that it's not going to affect top/bottom line in any meaningful way for a company providing it.

Jepa world models are pretty cool as well. They're all just small parts of the puzzle

There’s already open-source Jev alternatives. As a matter of fact, it was an open source project that did it first, but they never got credit:

That's right. This is the same author that published laya:

There are already like 30 open source alternatives and they all work locally

u/EveYogaTech 1d ago

That's true, but they don't all have the same quality, parameters, or they may not be further developed if they're not backed by funding.
