Hy3
- deleted 4mo ago[deleted]
- minraws 4mo agoI tried out the model it's pretty great, better than ~~gpt5.4~~ gpt-5.4-mini perhaps, atleast close enough to sonnet 5 in performance that I didn't notice much of a gap. Not really at gpt 5.5 tier though, and probably below glm 5.2... But most of all it just works for me for most things I tried and it's exceedingly cheap so there is no reason not to use it, if you need a foss model. Edited: gpt-5.4-mini not the base gpt-5.4
- theplumber 4mo agoI think you’ve got the models wrong…gpt-5.4? I doubt there is any open source mode matching it. Maybe in a year
- cbg0 4mo agoHy3 DeepSWE - 28% GPT5.4 xhigh DeepSWE - 52% A lot of contaminated benchmarks in the blog post about Hy3, needs real testing though I have a distinct feeling it's benchmaxxed like a lot of Chinese models.

- nshotton 4mo agoThis model is shockingly small for how capable it is. its a little bit bigger than deepseekV4 flash but around as capable if not more on some benchmarks than V4 pro, i wouldnt be surprised if this becomes a popular local model.
- nunodonato 4mo agohardly, its still quite big unless by "local" you mean people that spend many thousands on rigs :)
- nshotton 4mo agoYeah i shouldve been more clear, a model of this size could run on 2 dgx sparks so out of the range of a lot of the typical consumer sure, but I think there is definitely a market for that size
- andai 4mo agoI've been wondering about that. GLM-5.2 is also half the size of DeepSeek V4 Pro. (But costs roughly twice as much.) I looked into DeepSeek's architecture a little bit and the main focus was how can we save as much money as possible. They did a lot of cost cutting with the attention mechanisms. This allowed them to offer an insanely cheap price even on massive contexts, but seems to have come at the cost of performance? At least, that's my guess, when I see smaller models costing more and outperforming, I think, "they must have denser attention?"
- wgd 4mo agoThe current Deepseek V4 Pro is still just their initial preview AFAIK, with the "real" model release rumored to come later this month. GLM-5.2 might be outperforming simply because it's had more post-training on top of the GLM-5 base.
- VulgarExigency 4mo agoIf the "final" release of Deepseek V4 Pro outperforms GLM-5.2 while maintaining the current Deepseek price, then it's going to be a marvel.
- nunodonato 4mo agoVery impressive model for its size
- handzhiev 4mo agoIt's a very good model for this size and price. I tried it with a couple of small tasks - just an year ago this would be the level of the leading models.
- Catloafdev 4mo agoCurious how people feel about this compared to DS4 Flash, given they are pretty close in size. Also curious how well it holds up to heavy quantization. DS4 Flash can currently run reasonably well on systems with ~96gb+ RAM, I wonder if Hy3 can compete there.
- nunodonato 4mo agoDS4-Flash is not only "significantly" smaller, it will also benefit from a lot more speed thanks to DSpark
- Catloafdev 4mo ago299B for Hy3 vs 284B* for Flash Edit: fixed, got bad info
- nshotton 4mo agoflash is 284b isnt it? https://artificialanalysis.ai/models/deepseek-v4-flash https://artificialanalysis.ai/models/deepseek-v4-flash
- Catloafdev 4mo agoOh, it is. I was looking at the Huggingface repo which listed the lower number at the top of the page, looks like that's wrong.
- nunodonato 4mo agoSame, I was relying on that. Weird!
- wolttam 4mo agoHy3 lacks the DSv4 architecture's KV Cache efficiency. Whereas I can run DSv4 Flash on a pair of DGX Sparks and have enough memory left over for 3M tokens of KV cache, with Hy3 (quantized to FP4), there is only room for ~130K tokens of KV cache.
- james2doyle 4mo agoBeen using this and GLM 5.2 back and forth. I like the speed of Hy3. Also seems very happy to follow instructions. Still haven’t found any open models that follow instructions as good as Mimo v2 pro though
- SwellJoe 4mo agoMiMo v2.5 Pro is very spiky, in my experience. Sometimes excellent, sometimes mediocre. Weirdly high non-deterministic behavior. Run the same task three times, get three different results. I mean, they're all rolling dice for the next word, but MiMo seems to run hot on the randomness dimension in my benchmarks. But, it performs very well for its size. I just looked it up, and it's much smaller than I thought it was when I was testing it. 310B A15B is tiny for how well it performs. I guess that explains why it's so cheap.
- SwellJoe 4mo agoEr, actually, Pro is a big 1T model (which makes more sense given how well it does, sometimes). Regular MiMo is small, and I haven't tested it.
- throwaway2027 4mo agoQuite interesting to see them and Meta and others release before OpenAI supposedly is to release GPT 5.6 today, would it be better to release it before or after? Calm before the storm type of thing?

- minimaxir 4mo agoA month ago I wrote a blog post about how Hy3 was topping the OpenRouter rankings despite no one talking about it: https://news.ycombinator.com/item?id=48317294 https://news.ycombinator.com/item?id=48317294 As of today, it has fallen to 8/9th on the rankings. I don't see a reason where you would use this model over competitors. However, price economics are bit confusing, as currently the effective input price of Hy3 via OpenRouter is now the same as DeepSeek-hosted DeepSeek Flash V4. https://openrouter.ai/tencent/hy3-preview https://openrouter.ai/tencent/hy3-preview https://openrouter.ai/deepseek/deepseek-v4-flash https://openrouter.ai/deepseek/deepseek-v4-flash
- Miner49er 4mo agoI had to stop using it because I was getting rate limited like crazy. Probably why it has dropped. Seemed like they couldn't keep up with demand.
- andai 4mo agoThat was the preview model right? This one appears to be significantly better. I mean it's still a small model, but at least the benchmark scores (incl. on DeepSWE) went up significantly. It costs as much as Flash, but the benchmarks are on par with Pro (or above in some cases). Of course, benchmarks are mostly meaningless -- the only real benchmark is the actual work you give it :)
- BoorishBears 4mo agoWrites pretty engaging prose, finetunes well, now MIT licensed... what's not to like? Oh and very good world knowledge for the size: better than than DS4 Flash
- Azantys 4mo agoDo people really use 100B+ models for writing? I am no writer but to me it seems like writing is one of the easiest tasks with barely any logic or reasoning and as long as its not longer than a handful of pages I expect even 8B models to perform great.
- doawoo 4mo agoThat UI demo page is… really quite janky.
- simonw 4mo agoPelican from a few days ago: https://simonwillison.net/2026/Jul/6/hy3/ https://simonwillison.net/2026/Jul/6/hy3/ - I was using the free tier on OpenRouter, which expires on July 21st. I tried the preview model 41 days ago and got a pelican with a "change pelican color" button: https://static.simonwillison.net/static/2026/hy3-preview-pelican.html https://static.simonwillison.net/static/2026/hy3-preview-pel...

- invictati 4mo agoSome things are better left unsaid.
- righthand 4mo agoWhy? “Because it looks foolish!” This account is anonymous. Who gives a fuck? I will write to whomever I want.
- kordlessagain 4mo agoI will vouch for Simon. I do not know him personally. To me his posts are honest and inspirational. > I have been overly critical and arguing in bad faith about your writing in the past I think you are just critical without a stated valid reason. Arguing in bad faith seems to be a thing if HN history is the judge. And this is coming from a critical thinker, who is a bit tired of people firing off "human slop" comments. The Internet is full of a lot of people, but even when a few are bad apples, it spoils the lot. Maybe that is the intent. Maybe you are just grumpy for your life's situation. It is 100% possible to build software entirely with AI. If you don't do that, that's great! I still code by hand from time to time, and I'm reading a lot of Rust nowadays, and learning the ropes. I come from a strong Python and Javascript background, plus networking and operations, which I'm a whiz at. I don't do it anymore, but I know how to inform it is done properly. With this power, I can build things nobody wants to build, but me. Doesn't mean one has to put it into production, or it has to pass some security test, although with me driving it probably will. It only need be what is important to the end user, the prompter, to matter. I think Simon helps people with this mindset be better at what they love to do. And for that, we should all be grateful.
- thot_experiment 4mo agoI feel like I'm taking crazy pills with hy3, it's either benchmaxxed to hell and back or skill issue on my part but I'd rather use dense gemma. I don't think there's a single model that's wasted more of my time in recent memory.
- SwellJoe 4mo agoThe Hy3 preview has been a mediocre performer in my benchmarks of security auditing with models, and yes, it is outperformed by Gemma 4 (31b soundly beats it, the MoE does slightly better, even at 4-bit quantization when using the QAT version). Qwen 3.6 27b also beats it. I'll try it again now that it's out of preview and has been updated with more post-training. It presumably can't be worse, so maybe it's better enough to compete with a 31b model.
- andai 4mo agoFor context Hy is 295B, roughly on par with DeepSeek V4 Flash (284B). I haven't tested it yet so I cannot comment on the quality (nor the comparison with 10x smaller (!) models)
- thot_experiment 4mo agoThere are extreme diminishing returns in real world performance as models get bigger. 10x bigger might mean 5-10% better on benchmarks, a margin that can easily mean it's functionally equivalent in real world use or even a worse performer depending on the context it's being used in, and how good you are at providing meaningful context. Of course the bigger model embeds more knowledge, but when neither model has the knowledge necessary to perform the task, hy3 makes idiotic decisions all the time whereas gemma 31b has a decent hit rate. hy3 feels like someone who's read a lot of books and says the right words but has nothing of substance between their ears, gemma feels like a reasonably intelligent person who doesn't understand the domain, the latter is muuuch easier to work with than the former.

- docheinestages 4mo agoWhat we really need is a breakthrough in inference or LLM architecture to allow running GLM-5.2-level models at the size of Qwen 3.6 27b or smaller on consumer devices like a 48GB Macbook Pro, and at least at 100 tokens/second. My hypothesis is that a smaller, less capable but faster model paired with a good harness can run for longer and brute force its way out to solve problems that the bigger models can one-shot.
- cyanydeez 4mo agoim more expecting the harness to be a literal LLM, Like how you put vibration dampeners on all kinds of mechanical structures
- redwood 4mo agoThat would be great during the winter months
- docheinestages 4mo agoWhy not! And free hot showers during the summer. Just looking at the progress made since 2023, I don't think the LLM architecture we have today is the most efficient. We need creative game developers to start making LLMs.
- fc417fc802 4mo agoUnfortunately I don't expect indie game devs can afford high spec hardware at current prices.
- red-iron-pine 4mo agoused to heat my dorm room with a Pentium D that I overclocked and pointed a small fan at. Could open a window in winter, turn off the room radiator, and keep it cozy. perhaps at-home LLMs will bring me back to that. fun days of hacking and thermodynamics.

- wormius 4mo agoYes, I was gonna say... Today, I am this old.
- assimpleaspossi 4mo agoI would never use any product that can't explain on its own front page what it is and why I should use it.
- andai 4mo agoIt's like a computer, but you can talk to it.
- assimpleaspossi 4mo agoIf they can't tell me what it is or how to use it then they can't explain to me how to install it or anything else properly so forget it. I'm not wasting my time trying to figure it out.
- 3012756 4mo agoCongrats, the trial chat is QR locked. The AI companies are spoiled and get crazier every day (not only this one, US companies as well).

- freecodej 4mo agoNice
- Roguelazer 4mo agoGot really excited for a minute that the long-standing [Hy](https://hylang.org https://hylang.org) project had had a release, but it's just some confusingly-named LLM. Shame.
- linzhangrun 4mo agoThe strange names are mainly initials from Chinese pinyin. The first generation of Tencent Hunyuan was released in 23Q3, so it is already quite a veteran.
- jszymborski 4mo agoI'm sorry but what on earth is going on with that bar chart, the bars are not consistent. E.g., in the frontierscience-olympiad chart Hy3 preview scores the same as DeepSeek (70.0) but Hy3 preview's bar is visibly lower.
- mattstir 4mo agoThis is admittedly an aside from the content of the post itself, but... why do so many mobile sites insist on preventing zooming in and seem to share the same incredibly buggy image zooming? It's quite frustrating.
- rw2 4mo agoThere are now 3 tiers of competition: -Fable + Gpt 5.6 Sol -Opus + Gpt 5.6 Terra + Grok 4.5 + Muse Spark 1.1 -Open Chinese models: GLM + et family The economics is on the Fable tier people are willing to spend a lot on it and on the Open tier you have to give it away to drive usage. The bottom tiers are also getting more and more competitive.
- baalimago 4mo agoWorse than GLM-5.2, much more expensive than deepseek v4. Tough bargain.
- ponyous 4mo agoInteresting way to show off a model last on every benchmark. Not sure any other lab is doing this
- svantana 4mo agoMore like second-to-last on most of them, to my eye. Which is impressive as it's smaller and cheaper than the others.
