strongly disagree with it being a minor thing. its actually a major advancement in cost and capability for a not insignificant portion of what people are doing with LLMs today. the hype is there for a reason.

Jev may have its (narrow) use cases but the hype you see around is the perfect representation of the fact the greatest part of the AI bubble don't know what is important and what is not. Jev is a minor thing happening on AI compared to all the rest, yet the hype exploded.

There's a pg1 post on HN right now arguing that you can do Jev from any LLM. Functionally, sure, but not if you want to deliver the same latency and cost requirements in the same form factor. Without those requirements, though, you can't serve the same use cases.

On one hand, you can do what Jev does now with any traditional LLM (even as small as qwen 9b) - ask me anything. But to get it done at the quality and speed of Jev is the big use-case. AI developers in the meantime were excited about AST in a harness so industry dev is like a year behind anyway.

Side note: we were doing a lot of this with functiongemma last year and you can tune that openweights models for things like intents in an app, but it's roughly the same running cost with lower quality than LoRA on a small model.

Another side note: If you were one of the ones interested in AST just go look for Treesitter and related MCPs. Depending on how goofy your codebase is, that's a 30-80% savings on tokens just using one single tool.

Yeah. You can ask it to respond in json with a specific structure and it will (or it will at least try). Providers that support this are better than just directly asking the model. All major providers support requesting structured output including open source projects like llama.cpp etc

when you can dramatically reduce both cost and latency of results from models, you can unlock a _lot_ of user-facing outcomes that just wouldn't be possible with current LLMs without ruining user experience

Yeah l agree. I used to experiment with trying to get small llms to do something useful and landed on a solution in which it emits a word from a range of responses, which then triggered a deterministic workflow of some kind. l can see how that set up could be supercharged with jev

like we are talking about a model that returns in milliseconds results that often beat frontier models with _zero-shot_ prompting. claiming this is "just hype" is imo extremely close-minded

I think it’s more like “this implementation is nothing special” Seeing that this was a Big Opportunity should probably still get you something tho Maybe Jev the model is not technically impressive or unique and is supplanted entirely in the next few months

That’s part of the pushback yes, also there are a lot of projects that just wouldn’t benefit from it. But there already are other system-1 creatures walking the earth bsky.app/profile/jshe...

Laya is a new system 1 model like Jev, but it might be slightly smarter and faster than Jev. Created just moments ago ;) by author of two papers describing the architecture that were published last year.

I just came back to this thread because the release prismml.com/news/bonsai-... of Bonsai 2 happened around the same time. (atleast, it did for my life haha). I like where this is going.....if only I could self hos bonsai 2 on my 3060 (12GB) gpu lol. Thank you for posting this video-super helpful!

i'm kinda torn on it honestly on one hand it's a very cool generic model on the other hand a lot of classification tasks are very specific and there are better specific models for it still cool though as it encourages experimentation

that is true, but there's a lot of cost that comes with both training and running classification models, especially at scale. but its also not just for classification tbqh!

yeah good point, saw it mainly be used for classification tasks though, that's why i focused on it excited to watch that area of models to see how it develops!

if Jev! works on your task, there’s certainly a simpler model you can replace it with, and …

you can gain half the available skill on any typed decision problem by projecting a bag-of-words from the training corpus onto the class vector

also kinda sad that everyone is jumping onto the jev hype when laya exists kind of a "holy shit, two cakes!" situation though

the concern I have is people using jev as a hammer and assuming every classification problem is a nail for it. if there is existing training data, jev will at least cost more and/or perform worse. but in all scenarios where no training data exists, which is most of them, jev is very valuable.

new tech will take time for people to understand. it interfaces closer with data science which has a very long history of modeling, so most people who just got into this stuff from LLMs are very confidently asserting things that jev can do but really shouldn’t. but jev has a lot of uses still!

i do suspect it will get over used, but i’m also very confident it will help a ton with the training of new classification models. having something to use as a ground zero for training new models is pretty great tbh

yeah I have a feeling “decent and low cost universal classifier” is going to be a product from all of the labs soon, so data labeling for many problems might get really cheap.

its product thinking vs engineering thinking technically, Jev is *not* interesting, and that’s why all the labs overlooked it but also, it changes everything

... yeah... I've been working on classifiers since BERT like a decade or so ago Jev is better

Jev is interesting to me precisely because it's more boring. It doesn't seem nearly as impressive as natural language output, but I can immediately think of a lot more practical uses for it.
