contrary to what i feel is extreme negativity of the author, to me it seems Jev is one of the only novel releases that lived up to the hype and has staying power. Not only that it jump started a whole new "classifier" war, leading to now things like cloudflare's clairic for extraction.

really early to call it "the fall of jev"

Jev just works.

We use it in production. Tested a bunch of alternatives (openai decision api, llm based approaches) and they are either too slow or not as good. But mostly too slow.

Also really early to call it the rise of jev. Hackernews is the only place I have seen talk about it

The rise and fall of something that majority of people never heard of

FinnLobsien 1 hour ago | parent

Did Jev take off briefly and stopped getting talked about a few days later? Yes.

But that doesn't make it a failure. In the era where we have:

a) an AI hype cycle where the benchmark of "successful product" is ChatGPT, Claude Code, etc. b) a social media environment that only rewards the most-engaged content

It's easy to declare something "fell off" because it didn't immediately revolutionize how everyone does their daily work.

But by that measure, nearly everything is a failure, even if it creates great businesses. That's especially true for infrastructure that runs in the background.

They literally raised $870 million this month. It's like people think the hype cycle = success of business for some reason. I'm sure a couple of months later, they're going to release something new, hire a lot of PR, and the same people will be "man, Jev had fallen but this new [xyz] brings them so back! [xyz] industry will now be dead!"

Agree greatly. decision AI model is getting more common on the room of both of product and research.

andyferris 1 hour ago | parent

As someone working on decision AI models well before Jev, yes, I can’t see the concept disappearing or becoming less impactful/important.

ordinaryradical 1 hour ago | parent

Jev is already at $100M ARR, right?

The author ironically thinks people talking about a product is more indicative of its success than its success – which is hype, the very thing he railed against.

JKCalhoun 38 minutes ago | parent

I suspect the author is treating "hype" as a leading indicator.

(They may be right.)

nameless912 56 minutes ago | parent

Yeah like...I incorporated Jev into a shipping product. It's live. It's most certainly not dead or I would be getting paged right now.

Likewise, I switched over about 20 frustratingly buggy llm judgement calls that were using Luna (should the model use X tool, should it trigger deep research, what topic is the question etc.). I had spent days tuning the prompts to get somewhat decent results - meaning correct maybe 70% of the time.

I told an agent to test switching those all over to Jev. Came back a couple of hours later, thinking of this as an experiment, no major expectations, to find that they were all giving 100% accurate results in 800ms median time.

So it got adopted in a couple of hours work, it's live now, working very well, and I haven't had to think about it for the past week. That's the definition of a successful product.

EDIT: I should note two things

- there was actually one non English case that didn't have such high accuracy, now that I think about it.

- I assume a big part of why I got such good results was that I'd already spent ages tuning the prompts for Luna

OpenAI has a decisions API now so you didn't even have to migrate to Jev at all. Personally I'm using the open weight D3 decision models which work great and work locally on everything from phones to beefier computers due to the range of models they have.

zer00eyz 51 minutes ago | parent

> and stopped getting talked about a few days later? Yes.

No one was talking about PHP last week either. Till we all got a reminder that a massive chunk of the web is still happily running on it.

Being talked about is a terrible metric for anything other than how much people are talking about something.

alex7o 43 minutes ago | parent

E every 2 weeks we have a new hype cycle so all in according to how stuff already works I don't see something special here. I use jev, but it does not solve all my problems.

> I really don’t want to bash Jev

Sure. And yet...

christkv 1 hour ago | parent

Doomerism + Wishful thinking. We are what ~3 years into mass adoption of llm tech? Every couple of months it improves. Jev came out a couple of months ago and there is nothing that makes me believe that it will not improve over time as people fine tune small models to work better over time.

pmdr 1 hour ago | parent

Jev is still extremely useful for its intended purpose, not the mildly interesting hype on social media.

bsenftner 1 hour ago | parent

Jev feels like what happens when people that have had no serious statistics get a glimpse of what statistics makes possible. I'm not talking about the developers of Jev, I'm talking about the uninformed that went all hype cycle on it. It's well designed and the advanced system a good statistical programmer would write.

freecodeio 1 hour ago | parent

I think there seems to be extremes in both ends and in my opinion neither of these extremes are the ICP. If you're using AI to finish your work, you're not the ICP. If you're building a product and want to implement AI in your product, you're the ICP.

tpetry 1 hour ago | parent

The article says that other models are better at performance or cost. But whaz is not mentioned? Models that are _better_. From my testing, most models are much worse. And if you do an analysis on quality/performance/cost no one is beating Jev. Heck, no one is beating it at performance and cost at the same time.

There‘s a lot of hype with many releasing their decision models the past weeks. But all are worse. So maybe the years they spent in stealth is something you cant replicate in two weeks?

hanifbbz 1 hour ago | parent

Look up Laya. Also the notion of "best" is flawed because half of that equation depends on the use case. Benchmarks try to answer that by creating artificial use cases and test in isolation but that's not the concrete answer for a given use case either.

What a low quality hit piece.

solyin 1 hour ago | parent

In the digital age, the "fall" of anything just means you, and the people in your bubble, stop using it. It could be something that enough people get value out of it that they can afford to pay for the domain name, and a bunch of other stuff, and you'd never even know. So to claim anything falls, well. There's Yahoo, AOL, Kodak, Snapchat, Facebook, Twitter, and Zombo.com. And they ain't going away.

I use Jev in production. Hype or no hype it’s working.

handzhiev 1 hour ago | parent

Same here, it's fast, cheap and fairly reliable for my use case.

yitchelle 1 hour ago | parent

HN has a funny was of bubbling up low value article such as this. Jev is far from being a fallen software. It works and it works well. Just because no one is talking about it does not make it a failure.

BoorishBears 1 hour ago | parent

We reached inverse hype: where the folks jaded by hype are so jaded that they start to hype the same low value content they normally deride... as long as it speaks counter to any hyped topic.

Ironically, that technique usually pans out since a lot of useless fads get hyped. But every once in a while it causes people to completely and utterly miss the point.

Ozzie_osman 1 hour ago | parent

Seems to be doing fine as per Openrouter rankings: https://openrouter.ai/rankings#leaderboard-table

It's the top model for classification.

hanifbbz 56 minutes ago | parent

Yeah but do Openrouter stats represent local classifiers? Unlike LMs decision models are quite likely to run at edge, especially because their utility for a specific task improves with training.

zhisme 1 hour ago | parent

did author used jev by any chance?

this actually very useful where you can rely your classical programming logic with coefficients provided by jev decision model results if (jevResponseJudge < 0.3) doSomething() else doNothing()

how would u code with LLM in such cases? parse responses for keywords? xd

no, they provide very useful interface. Just try it before writing posts about "hype".

armcat 1 hour ago | parent

After reading the article I can see that the comments here are a bit off. For example see this quote from the article:

> It’s not dead. Some companies use it while I believe the majority of use cases are addressed by open-weight rivals.

The point the article is making is the incredible way Jev specifically caused insane hysteria and hype, and just as suddently faded away. Not that it's dead or that the concept is severely flawed.

owebmaster 1 hour ago | parent

Yeah no, it's too early to make any of these calls so the title is clickbait, the article thesis is false.

senordevnyc 1 hour ago | parent

No, it reads to me like the author got over-hyped at the launch, and then fell into their own trough of despair, and now that means AI is a bubble.

alexey-salmin 39 minutes ago | parent

The article itself contains more hysteria and hype than the actual Jev launch had. Maybe the author should just calm down a bit.

Kuinox 1 hour ago | parent

> It’s not dead. Some companies use it while I believe the majority of use cases are addressed by open-weight rivals.

The quality of the answers on my datasets are in another league compared to the benchmarks. I have a mixed language dataset, Jev answers only lack some accuracy, the open weight rivals output just look like random noise

leemoore 1 hour ago | parent

Typesafe over-hyped their useful product and successfully got it in front of AI devs. So to be assholingly snarkily reductive I can sum this up as "founder did founder shit well"

hanifbbz 46 minutes ago | parent

They knew exactly what they were going for. Hopefully posts like this keep founders on their toes instead of normalizing this "founder shit".

The crime of hyping your own solution against trillion dollar companies

If this is Jev’s trough of disillusionment, I’ll happily trade them for my plateau of productivity.

hanifbbz 48 minutes ago | parent

Seems to me most of the comments here miss the main point of the article about the pattern of hyped marketing (name dropping and jargon, ambiguity and inflated expectations, drama).

aeon_ai 34 minutes ago | parent

The author is obviously informed, but just as clearly biased.

Accused Dario of being part of Ilya’s coup against Sam Altman (now retracted), stated “ It’s an open secret that the training data wasn’t legally obtained anyway” when fair use has very clearly been established, and panders to the anti-AI doomer crowd with talk about how AI won’t be useful economically until we can get to the energy efficiency of the human brain while still invoking the boogeyman of killer drones and cyberterrorism.

Jev was overhyped, and the marketing was clearly looking to coin a few buzzwords, but the author seems to be intentionally ignoring the pace of development, the erosion of traditional intellectual property assumptions, and the realities of the technology. It can be overhyped, but this is very clearly the telos of all technology.

kypro 31 minutes ago | parent

I've said it before, but the most surprising thing about Jev was that no one thought of doing it before. And second to that, that so many people didn't realise how useful classifiers were...

It seems a lot of the stuff people have using LLMs for in recent years were things that would be better suited to a classifier model.

Classifiers are not particularly difficult to train, but they also not as easy as just throwing an expensive LLM at the problem. That's really only the problem Jev solved. They've not done anything particularly technically impressive (imo), but they noticed the market for lazy/poorly informed people misusing LLMs for classification tasks and built a better solution.

I see no moat in that, but good on them for building something that is clearly useful and solves a real problem. The only thing I personally dislike about Jev is their Reddit-speak cringe posts and all the marketing nonsense about AGI. Although I'd be willing to believe that could be deliberate and they know their target audience are nerds with AI-psychosis.
