AA shipped a new benchmark last week as part of the Intelligence Index v4.3 update — a brand-new private eval that replaces τ³. Astra was farming a ton of points on it and used those to get even with Fable, but… looks like we have a new king.
So they changed the index twice in three days to make Astra look not-quite-worse than Fable, and then a random guy quietly took first place on it.
Hi everybody, we post-trained Qwen 3.8 27B to be more efficient by figuring out which tokens were linked to overthinking and penalizing them without "attacking" the reasoning length directly then fixed the accuracy with a bit of secret sauce (hint On-Policy Distillation) and achieved great results (-58% thinking tokens, 1.95x speed up, <1% accuracy loss) so we wanted to open-source it and hear the feedback of the community.
This is the link to the model: https://huggingface.co/ukisai/Swift-Qwen3.8-27b
We also also providing a Free Research Purpose API (OpenAI compatible), courtesy of Nvidia who were kind enough to provide us with the GPUs. You can use it to try out the model if you do not have enough compute to run it, it's limited at 5RPM. https://ukisai.com/api/swift/v1/models
We also made a GGUF (Q1-Q8) and there's also a few nice community (Bartowski) quants with even lower/higher precision. The community also created amazing NVFP4, W4A16 and Uncensored versions of the model you can find on Huggingface.
IMPORTANT: Our training approach is not a replacement for the reasoning effort settings, chat templates or token caps but is complementary and targets a completely separate issue (overthinking and "anxiety-like" reasoning loops prior seen in PTQ, but as far as we identified also prominent in BF16 of this size class LLMs as well). Contrary to popular belief, these specific patterns do not contribute to answer quality when properly targeted. (our thesis being: reasoning length IS extremely important and should NOT be shortened by force, but rather optimized). This is also demonstrated bellow in our xhigh vs medium effort benchmark table. The goal is to keep xhigh accuracy while reducing only the unnecessary part of thinking.
I will TLDR you on our thought process, research, training and benchmarks.
The benchmarks: (raw benchmark files here - https://github.com/UkisAI/Swift-Qwen3.8-27B-evals/ )**
Swift-27B vs Qwen3.8-27B (BF16, all benchmarks ran x5, thinking effort xhigh)
|Benchmark|Qwen3.8-27B|Swift-27B|Median tokens|
|:-|:-|:-|:-|
|GPQA-Diamond|88.4%|88.3%|58% fewer|
|LiveCodeBench v6|76.8%|81.6% (+4.8pp, due to default truncation in LCB it is not performance gain)|46% fewer thinking tokens|
|Terminal-Bench 2.1|66.7%|65.8%|39% fewer|
|MMLU-Pro|85.5%|85.0%|28% fewer|
|C-Eval|90.0%|90.6%|19% fewer|
|IFBench|73.5%|71.8%|51% fewer|
|AIME 2026|98.7%|94.0%|50% fewer|
|HMMT (Nov 2025)|99.3%|96.0%|46% fewer|
|ERQA (vision)|67.5%|66.3%|55% fewer|
Token savings hold at every reasoning effort (mean thinking reduction): xhigh 41%, medium 23%, low 26% (albeit with accuracy loses of 1-4% on medium and 1-2% on low which we need further testing for)
Swift at xhigh vs the base's own effort settings on GPQA-Diamond (198 questions x 5 seeds):
|Model / effort|Accuracy|Median tokens|
|:-|:-|:-|
|Base xhigh|88.4%|6,642|
|Swift xhigh|88.3%|2,771|
|Base medium|84.1%|1,753|
So Swift keeps xhigh accuracy at under half the tokens, and beats base-medium by 4pp at roughly 1.6x its tokens.
End note:
While we are keen on complete open-source, we still need to keep a part of our training and data private, being a new lab. The license is not Apache 2.0, but it only affects companies >$1M. We hope this does not pose a problem for the community, but we are open to feedback on it.
We want to contribute as much as possible to the community and would really appreciate feedback on our work, quantization or Swift model requests. For context, we are working on Swift 3.8 Flash Next right now and have so far gotten up to -30% thinking token usage while maintaining xhigh accuracy, which we take as a strong indicator our methodology is reproducible across the Qwen model family. Will explore other families as soon as we have the capacity and would love to see which ones the community would love for us to optimize first.

Cautionary tale about chasing cheap tokens.
exposé: https://kendell.dev/blog/crofaifalse/
reaction by nahcrof, announcing the shutdown of the service: https://x.com/nahcrof/status/2099552389434900643 - now deleted, archive picture: https://i.imgur.com/teOQngH.png
NahCrofAI (crof.ai, nahcrof.com) was an inference provider which had all the latest models at the cheapest price, often significantly below the lowest alternative on OpenRouter. The owner claimed that they are running custom inference engines that allows them to offer tokens for dirt cheap, and other providers are suffering from "skill issues", that's why they are so expensive.
In reality:
kimi-k3 are sold at $2/$10 in/out, but instead routed to GLM 5.3 Flash via OpenRouter, representing a 13.3x multiple on input, and 20x multiple on outputgreg-2-ultra routes to GLM 5.2, greg-1-mini routes to Qwen 3.5 9B. greg-2-super, greg-1, greg-1-super routes to Kimi K2.7 Code. All of these at a significant markup compared to the actual model being served. CrofAI admits in DMs that his claims of the greg family being made by him is a lie.CrofAI responded to the exposé by announcing the shutting down of their service; after their failure to provide their own inference, they promise to provide one last thing: a refund to those asking.
UPDATE: around 4:30 AM UTC of Sept 15, the owner published a now-deleted blog post (archive image) writing under the fake pretense that it's his "team" authoring it, stating all of CrofAI founder's claims "were written under a lot of stress, and they described the situation as worse it was", and that a new team is taking over, with the service being resumed in 2 weeks.
At the same time, the CrofAI twitter account was also supposedly "taken over" by the team, starting each twitter reply with "Hey, Nathan here", stating the founder is stepping back and a "team" is taking over everything. This fake pretense act only lasted a few hours, and scared either by the public not buying the Nth fake story of the pathological liar that CrofAI is, or by the public's replies reminding him that what he committed is numerous counts of wire fraud, he has now deleted all his online presence: nahcrof.com and crof.ai return 404, Twitter page is deleted, /r/CrofAI sub is now private.
Here is another image of the owner admitting that he was defrauding customers for the entire 2 year operation of his service, then begging the investigator to help him cover his tracks and not expose him
EDIT: Commenters pointed out that NahCrof is 4chan in reverse. The owner's Discord name was "Devious Flimflam". Flimlam is defined as "deception, fraud". Looks like it was a deliberate scam operation from the get-go, and the owner's age was among the many lies.
I cannot stress this enough: if you bought any credits (even if you used them up) you are entitled to a full refund for every transaction as the victim of fraud. Open a chargeback with your bank for every transaction made. If you used their API, assume that everything was logged and is currently being mined for personal information and API keys to sell on the black markets. Rotate your keys, change passwords, get a new debit/credit card.
With all the recent drama surrounding AI safety. It’s obvious that open source could be caught in the crossfire.
From initial testing it seems pretty solid so far. Asked it to compile the latest llama.cpp for CUDA and its doing well so far. If this thing holds up to its score then its SHOCKINGLY good for its size.
Xi emphasised the need to step up cooperation.

Note - This is translated from the actual blog link right at the bottom.
A few days ago, DeepSeek v4.1 was released. It raised the ability of small models to a new level.
AI is improving much faster than anyone expected. From the first ChatGPT that could only chat simply with a few thousand tokens of context, to models with real reasoning like OpenAI o1, DeepSeek R1, and Kimi K1.5 Thinking — that only took about two years. From reasoning models to agents that can smoothly use tools, run commands, and finish complex tasks — that took only about a year and a half. It’s hard to imagine what AI will be like in one, two, or three more years. How powerful will it be? Will it already be able to improve itself and deeply enter areas like embodied intelligence?
AI is getting better and better at writing operators
In the field I work in — designing and writing operators — AI has also improved very quickly. In just one year, it went from a small helper that could look up documents, read code, and find bugs, to an expert that can independently read CUDA, PTX, and SASS code, use professional tools to analyze the stall time of every instruction, and then optimize operators by itself. I believe that soon it will also be able to design operator schedules on its own, evaluate different schedules, implement them, and optimize them.
Of course I am proud of DeepSeek v4.1’s success — after all, its main Attention operator was written by me \[1\]. Its good performance is partly a recognition of my work. But the times keep moving forward, and technology cannot be stopped. I know clearly that in half a year or one year, the operators written by AI will most likely be as good as mine, or even better. AI can think 300 tokens in one second, type a command in half a second, and finish a piece of code in twenty seconds. I cannot. AI can keep improving in model depth, thinking strength, tool use (how often it interacts with the environment), and even parallelism. I cannot.
Humans have never hesitated when it comes to destroying themselves. Why do I still work hard to optimize operators, even though I know that the better my operators are, the faster our new models will train and run, the faster model ability will improve, and the sooner I will be replaced? One reason is that writing operators feels like playing a game to me. It gives me a lot of joy. When I invent a new technique or see the performance of my operator go up, I feel as excited as a speedrunner who breaks their own record. And when I see that my operator is much better than the official ones from the vendors, I feel very proud. But a more important reason is this: even if I give up or deliberately slow things down, other companies’ models will still keep improving and will replace me anyway. “Of course I hope I won’t be revolutionized. But if it has to happen, I hope the person who revolutionizes me is myself.” When everyone is so determined to destroy themselves, I have no choice but to join this cruel arms race.
What about me?
When the day comes that AI writes operators better than I do, what will happen to me?
My judgment is: I probably won’t lose my job completely, but I will have to change careers. I can still keep a job, but I may never again be able to do the work I once loved.
I once made a judgment about the changing times and my own future: because things are changing so fast (the AI progress above is a good example), I cannot predict what will happen in five or ten years. But no matter what, I believe that with my vision, judgment, initiative, and intelligence, I can stay in the game and stand at the front of the times again. However, this judgment only guarantees that I won’t become unemployed. It does not guarantee that I won’t need to change careers. In fact, it encourages me to change careers in order to avoid unemployment.
What does changing careers mean? It means I have to give up the field of operator design, writing, and optimization that I have worked in for a long time and loved deeply, and instead become a “mecha pilot” for Agents. Before, my interests, what I was good at, and what industry needed were basically aligned. Now, AI has made what I am good at into something it is even better at, and industry demand has shifted from “people who can write high-performance operators” to “people who can use AI to produce high-performance operators faster.” To meet industry needs, I will have to leave the direction I loved and move to an unknown new direction. I believe that with my understanding of engineering, upper-level model needs, and lower-level hardware, I can still produce operators with high quality and high efficiency. I also know I might come to love this new direction (or I might not). But the feeling of having my passion taken away is really not nice. That quiet joy of sitting at my desk and calmly writing operators for a whole afternoon may become a final song this summer. I have to bury my talent in yesterday and become a mecha pilot. My hands hold more gears, but my heart has fewer rhythms.
Here is a simple comparison: You are an expert at knitting sweaters. You are especially good at creating patterns and matching colors. The sweaters you make are high quality and beautiful, so rich people from near and far ask you to knit for them, and you make good money. At the same time, you really enjoy sitting by the window with a cup of tea, looking at the green mountains, water, cows, sheep, and cooking smoke, and quietly knitting for a whole afternoon. But one day someone invents a magical machine. You only need to give it yarn and a pattern, and it automatically knits a sweater. The quality and texture are as good as yours, and it is much faster. You know that your colleagues can easily reach your old level with this machine, so you have to use it too. You also know that with the knitting skills you built over twenty years, even when everyone has the machine, your speed and quality can still be better than others. But that feeling of listening to the rain by the window, slowly pulling the needle and thread, and enjoying the quiet time is crushed by the noise of the machine.
I know this is helpless, but there is no other way. I can keep my job, but my old passion will most likely have to be given up. I am a person whose rational side and emotional side are quite separate. When I need to be rational, I can be very rational, but sometimes I also show my emotional side. I remember when I moved out of the rental apartment I had lived in for a year, I cried a lot because I didn’t want to say goodbye to the memories. Saying goodbye today to the era of hand-writing operators and optimizing them with the human brain is even more cruel.
I don’t know if any readers feel the same way, but I think this is just how things are.
What about people?
While AI keeps improving, I also worry about some questions:
Will students now be much more likely to use AI to finish homework, especially practical labs? Imagine there are two choices: one is to spend eight hard hours finishing a lab and maybe not even get full marks; the other is to start an AI model, spend a few cents and a few minutes, and let AI write full-mark code. Which one will most students choose?
The point above will cause many students to have seriously weak engineering skills — things like organizing code, building systems, thinking about future needs and designing for them in advance, and abstraction ability. As AI keeps getting stronger, are these engineering skills still necessary? Will they be abandoned by the times like the old skill of “writing x86 assembly fluently,” or will they always be valuable like the ability to “understand the whole computer system from software to system to hardware”? If it is the latter, then it is dangerous — a person with poor engineering skills, when paired with AI, can produce messy code several times faster than before, planting all kinds of problems in systems and making the world more of a “clown stage.”
In future society, will power become more important than technology or intelligence?
These questions may need to be answered by the times themselves.
Conclusion
With the development of AI, future society may move toward two extremes: communism or Cyberpunk 2077. In the first, productivity is greatly liberated and people’s living standards improve a lot (I’ll stop here so I can pass review). In the second, a few tech companies control most resources. Only a very small number of people can use the most advanced AI and technologies and get close to “mechanical ascension.” Most people can only use very weak AI. Crossing social classes will become harder and harder: you need the strongest AI first in order to cross classes, which creates a dead loop.
Guess what: if Anthropic forever holds the most advanced AI in the world, will future society become communism or 2077? You guess?
So I still believe that the most advanced intelligence should be provided to everyone in an open and cheap way. I do not trust that Anthropic or OpenAI will do this. Especially, I do not want Anthropic to hold the most advanced artificial intelligence or AGI. To put it strongly, that would be as serious as letting Hitler get atomic bomb technology before the Allies. That is why I chose and continue to stay at DeepSeek: we research powerful, fast, and widely beneficial artificial intelligence and open-source it. Maybe this can pull the world a little bit back from the 2077 side.
May the future world be well. May all the beauty be blessed.
\[1\] “Main Attention” only includes the MQA attention with head dim = 512. It does not include the indexer used to select the top-k important tokens. That part was written by other (also very strong) colleagues (and their AI Agents).
Prices have been going crazy, but it's about to get worse me thinks.
Two months ago I announced I had found a new dynamic quant method called Voodoo Quant which was SOTA for the most aggressive quant levels on some smaller Qwen3.5 GGUF models. I kept the methodology private at the time, but I've seen too many requests for dyn quants for various models lately, so I decided to give my method to the community since I don't have the time to scale this into something that could do it justice. Hopefully it will also inspire some researchers to find out more about it and improve it as I am just scratching the surface.
Here is the new toolset so you can now make your own dynamic quants: https://github.com/curvedinf/voodoo-dyn-quant
Many postulated on what method I was using, and its actually fairly simple and elegant: I found a way to use gradient descent to optimize the per-tensor quant layout.
What is a Dynamic Quant? Some model formats, namely GGUF, support quantizing (compressing) each tensor (set of weights) with a different quant level. Static quants make static selections of certain types of tensors having a set quant level. Dynamic quants make a different quant selection for each tensor of each checkpoint size.
How does Voodoo Quant work? Voodoo Quant runs all the quant levels of a model at the same time, for every tensor, and lets gradient descent pick which ones optimize loss the lowest for a given target filesize. Technically speaking, this is done by an epoch of training which freezes all candidate quant weights (as provided by conversion directly from llama.cpp's underlying library, gglm) and only trains a single scalar gate per tensor per quant level. The scalar gates of a tensor represent which quant levels are most optimal. Over time a tau level is annealed that helps the training freeze into singular predominant quant selections for each tensor instead of mixtures. Softmax is used so all quant levels receive gradient, even when a selection is mostly frozen. The quant selections are trained on a diverse calibration dataset. The training is then measured with a loss function which finds the KL divergence of the mixed-quant logits versus the reference BF16 checkpoint, rewarding a lower KLD, while also rewarding getting closer to a provided filesize target. This info should get you started on understanding what is going on, and for more details you can dive into the source!
What does the repo have? A complete set of tools to train your own dynamic quants using this methodology. It is currently set up for Qwen, but it can be adapted quickly for any model arch.
How does UD 3.0 compare? Unsloth Dynamic 3.0 is a proprietary methodology that unsloth has not revealed any details of (by the way, people were criticizing me for not revealing my methodology, but unsloth had been doing that for years!). However, we do know it is very good. In my testing, UD3 is better than VQ at high to mid quant levels, but VQ is better at aggressive levels. As far as I can tell, UD 3.0 is an advancement of static analysis techniques that are currently defacto. Static analysis means the weights of a model are analyzed in various ways using statistics and static functions, sometimes tuned by repeated runs benchmarking KLD and other metrics. Voodoo Quant is the first method to my knowledge that uses a backwards pass and gradient descent to choose per-tensor quant levels. Using GD to optimize quant levels requires a much more powerful system than static analysis, but technically speaking is more efficient at maximizing performance because it compares the equivalent of many more iterations of benchmarking runs than is reasonably possible via SA.
How well does Voodoo Quant work? This is a research grade project, and is not studied at larger model sizes. At smaller model sizes it is shown to be exceptional, as in the charts above, especially at the lowest quant levels which can benefit from more complex/diverse quant selections. I used research level control for my testing, but I don't claim that VQ has been studied to a scientific level of proof of effectiveness. A lot is still left to learn about how well it works, so I hope to see more research in this direction. I don't believe there are many dynamic quant open source projects out there, so I hope the community can use this to improve local models, and especially for low VRAM machines.
Why open source now? I have like a dozen irons in the fire for various other projects, and this is just sitting there when it could be used by the community. I have made many open source projects for 20 years, so its nothing new.
Peace!
Especially the 7B one seems very interesting, it casually destroys muse glimmer with a way smaller size. And they open source literally everything, every step of the way. Anyone tried that model? It can be a new milestone if 7b and 3.7b ones are actually good, and not just benchmaxed.
Maybe some of you know but I didn’t see any post about this. Apple just made available their AFM model on MacOS 27 natively. Just run fm chat in a terminal.
Disclaimer: I’m an open weight person. I prefer open models and ecosystem, but I’ll still open the discussion.
Did you test them? Build using them? Are these models good?
I feel like this is still a huge step in the direction of local AI that a company like Apple does this and release hardware optimized models.
So what do you think?
EDIT: Sorry for the unclear title. This model is UkisAI's Swift-Qwen3.8-27B, not a new version of BottleCap AI's 3.6-ThinkingCap. All credit goes to UkisAI for making great fine-tune, and I made this post to celebrate their work. I meant no disrespect by mentioning another model in the title.
I doubt I'm in the minority here when I say I love Qwen models, but the overthinking is a major timekiller. It was bad in 3.6-27B, and it's worse in 3.8. I know there are some who say, "well that's how it achieves such a good performance/size ratio"... But now there's some definitive proof that's not the case: UkisAI's Swift-Qwen3.8-27B!
This model seems to be inspired by Qwen3.6-27B ThinkingCap, which was the version of 3.6-27B I used as a daily driver before switching to the 3.8 series. For those of you who haven't heard of it, ThinkingCap is a fine-tuned version of 27B that uses about 40% less tokens to accomplish comparable benchmarks and general performance as the original model. It's one of those fine-tunes that actually works. I used it daily for months without any issues, and it saved me countless hours.
I had been waiting and hoping that they would release a similar version of 3.8, because it is so slow, despite its impressive performance, but so far none has been forthcoming. However, it looks like UkisAI also enjoyed that model, and took it upon themselves to deliver a sequel. They identified "reasoning-marker tokens that ... trigger overthinking in Qwen’s reasoning rollouts" and penalized them using RL, resulting in fewer overthinking errors. They also employed "a transfer component derived from BottleCap AI's ThinkingCap-Qwen3.6-27B". The end result is an average of 30-50% fewer reasonign tokens for the same quality outputs on a number of benchmarks (see the model card for all of them).
This claim is quite impressive, and I have independently verified their claims and the quality of the model in my own use cases and in coding benchmarks using Aider as an eval suite (with Q8_0 for both models):
|Metric|Swift-Qwen3.8-27B|Qwen3.8-27B|
|:-|:-|:-|
|Pass1 (%)|30.8|27.1|
|Pass2 (%)|75.7|77.6|
|Well-formed diff (%)|98.1|99.1|
|Completion tokens|7,301|12,547|
|Seconds/case|750|1,481|
|Total tokens/solve|12.1k|19.3k|
As you can see, their claims hold true -- Swift accomplished an equivalent success rate in approximately half the time, using 63% of the tokens! This is a huge win for 3.8-27B users, because of course decode drops off more and more the longer the response gets, which is why the time is halved even though the tokens are closer to two-thirds of 3.8-27B.
Anyways, my posts tend to get excessively long so I'll cut it off here, I was just really excited after finishing my eval suite on this model and wanted to share.
Now that the dust has settled a bit - here's a write-up on running Qwen3.8-Flash-Next (125B-A6B MoE + 51B n-gram table) on relatively middle-tier hardware (RTX 4070 12GB + 64GB DDR5-5600 + Gen4 NVMe on Linux).
I started out with bare 6 tok/s and through latest patches and optimizations getting close to 20 tok/s generation. You just need enough RAM.
For me this is the most intelligence possible on this machine right now. The 27B dense is not a choice because of low VRAM but may make more sense for other configs like 24GB VRAM owners. It actually surpasses the 27B model on most tasks as well so its great for Low VRAM, High/fast RAM configs.
PP is still a bit low at 300-350 tok/s.
What helped
\- Using AtomicChat's 4.27 bpw quant https://huggingface.co/AtomicChat/Qwen3.8-Flash-Next-GGUF
\- Ngram SSD offloading (lazy-mode)
\- --fit on --fit-target 512 helps automatically select the right params.
\- Master branch (19.35 t/s): Latest commit with MoE improvements.
- MTP Variant - PR #28243 + Compact MTP (20.65 t/s): MTP support is not yet merged so need to apply this PR enables Daniel Han's 1.78 GB \shared-Q4\_K\_M\ compact head. Combined with \-ncmoe 45\, it yields 77–96% acceptance and breaks through the 20 t/s barrier on every tested task (coding, summarization, creative).
With such low VRAM, MTP is not a huge jump because you have to give up a few layers to store the MTP head in VRAM. Only the shared + Q4\_K\_M in MTP gets a beneficial uptick.
Using commercial models to research, optimize and benchmark inference for local models helps a ton (GLM 5.3 flash with opencode go, so did Astra, Gemini 3.8 etc.)
Lot more details in the post (AI-assisted).
20B-A1B model is coming, good for low VRAM people?
Hey r/LocalLLaMA,
We’ve released our full ShapeLearn GGUFs for Qwen 3.8 27B.
TL;DR
Lite held up very well. As we expected.
We released ShapeLearn-Lite quants a couple of days after Qwen arrived: less optimization, targeted sanity checks, full benchmarking after release.
Then Unsloth v3 arrived with lower KLD at several comparable sizes. Lite looked overtaken, until the task results came in. Three of six Lite models made the quality/speed frontier against twelve Unsloth v3 models in our RTX Pro 6000 comparison. Pretty good for an impatient release. Full ShapeLearn now pushes that frontier further.
Which brings us to KLD.
Unsloth Dynamic V3’s UD-IQ3\_S had \~20% lower KLD than our similarly sized smallest Lite model, but scored 95.55% versus Lite’s 97.33% of BF16’s aggregate benchmark score.
Closer token distributions did not mean better task performance. KLD is useful to avoid a quant that has fallen over the edge, but it isn’t a quantization leaderboard.
That distinction is the subject of our paper on KLD and quantization fidelity, recently accepted for publication to the EMNLP 2026 Industry Track. We also released blog post version of the paper a few weeks back.
We benchmarked this release on RTX 6000 Pro Blackwell, RTX 5090, RTX 4090, RTX 3090, RTX 4080 and RTX 5060 Ti. The benchmarks we used to measure quality are: GSM8K for math, IFEval for instruction following, MMLU for general knowledge, LiveCodeBench V6 for coding, Multi-IF for multi-turn and multilingual instruction following, ACEBench for tool use and agentic tasks (both thinking and instruct), Multiple HumanEval for coding (thinking) and BFCL V4 for tool calling and agentic tasks (thinking).
If you want to dive deeper or choose the best model for your use case, the blog has the complete results across all tested GPUs, along with the methodology, model sizes, and full legend.
I'm like you guys and am constantly experimenting with new models, seeing what they're all good at, how I can make use of them for certain projects and goals. I've been using Qwen 3.8 27b for minor coding work and it has been impressive.
But with just regular chatting I have been impressed with Muse Glimmer.
It seems to be able to have the ability to follow and hold good, deep and meaningful conversations without coming off as a typical chatbot.
No repeated statements like "I hear what you're saying", "that sounds really deep..." none of what sounds generic or like it's blowing smoke up your ass. I was impressed with how natural it comes across just in natural conversation. I think it's one of the best "chat" models you could get right now as it's one of the only local models that doesn't feel like you're chatting with an AI when having a conversation.
I'm thinking of finding a way to run both Qwen3.8 and Muse at the same time. It's fun to play with these things.
I have a custom fork of llama.cpp designed around the ampere architecture specifically (though many of the upgrades also translate to faster performance of blackwell + lovelace). The recommended config supports 90+ TPS (for agentic/coding, at temp 1; greedy will of course be faster) through 100K tokens, with context of up to 240K.
If you want the repo, it is here:

I recommend running with this quant, which is \~ 4 K M quality but considerably faster (technically, a 3 K XL upgrade)

If you want the deep dive on how it is so much faster (80% vs the near comp at 200K!), at more context, there is a long form article here.

Running faster than API speeds on my 3090 (for 27b at least) has genuinely been a step change in the utility of the model + card for me. I hope you enjoy it!
This took roughly 5 hours to create, using 2 different configured harnesses, same model. RTX 3090, overclocked +12% gain (MSI Afterburner), Q4KM - built this for fun, will be throwing it on GitHub, opensource for people to get an idea of a project created to the near ceiling of performance & capability for q3.8 27b. & also maybe ya’ll can contribute to the game only iterating locally. It would be a fun little experiment.
I know I know, it's great, we know. I've been working on tweaking inference engines for a week now and it's been one shotting most of my vague prompts without any issues. It will even write tests and validate the changes without me asking. It's actually nuts.
Last time I did something with advanced math I was making a game using Sonnet. It took many iterations to get physics to work correctly.
Such a good model. I'm so glad I went all in on local months ago. I was so tired of Claude making every excuse it could to try to force a new turn.
I had all the data saved from AA's v4.1 index, so when they upgraded it in the wake of Astra's release, I could actually generate a before/after comparison.
All models are the same. The only thing that changes is the weighted sum of the benchmarks that compose the Intelligence Index.
Highlights
I am a beginner, Took a while to get started, get everything right.
This setup is native not container. Still not sure if I did this right, or if I can tune this more.

The full K2 Horizon lineup is out on Artificial Analysis.
The AA intelligence vs. parameters plots show that
\- 0.9B and 375B are bad
\- 3.7B and 7B are SOTA
\- 36B A4B is SOTA for hardware with poor memory bandwidth (spilled experts, Strix Halo, DGX Spark).
I'm going to take the AA Intelligence Index at face value here. This post is not about it.
The problem is that these models have a god-awful KV cache design. This means that you really can't use the number of parameters for "best in class" considerations, because these models heavily shift to the right on the plot if you replace parameter count on the X axis with RAM requirements.
For Q4\_K\_M weights, no drafter, no vision, 128k kvarn4 KV cache:
Compare them to
Notes: I don't advise compressing 2\~4B models to Q4 and I haven't tested these models' tolerance to weights and kv cache quantization yet. The above choices are just to keep the comparison fair.
This awful context design means that
So I would like to run qwen 3.8 27b locally for my ai agents, maybe even in parallel with other small LLMs (such as qwen3.5 9b, oss 20b etc..).
What is the best hardware to do this? Not a video card but I mean as “mini pc ai”.
Thank you 🙏
For years, the JVM has watched the AI revolution from the bench. Every model, AI framework, every breakthrough, built with/for Python.
jinfer is an inference engine built for the JVM from first principles: chat, vision, audio transcription, embeddings, reranking, and TTS. No Python runtime, no ONNX, no sidecar process, no wrappers; the whole stack is built for the JVM:
It integrates with Spring AI and LangChain4j, and has first-class support for GraalVM Native Image.
Where things stand: this is an early release. CPU is the main target today, and is already competitive with llama.cpp. GPU support via jota is in progress.

Hello Reddit. Posting this for fun. I thought it was a lonely and silly journey to set up Qwen 3.8 Next on a system that doesn't really run it properly—it was a challenge that might help the community. I have yet to benchmark this specific REAP version versus Qwen 3.8 27B QK4, but my assumption is that it will do much better, despite the hemorrhaged world knowledge.
As you can see, we have about 44.5 GB of actually addressable system and VRAM available. The iGPU is taking care of the OS to make sure the GPU is totally free—but still, this is barely enough to hold everything together. This config actually totally fails with any of the Unsloth quants—no, I needed something more aggressive. I found the perfect thing—this REAP:
https://huggingface.co/AnonimousA/Qwen3.8-Flash-Next-REAP-320-GGUF
What's so great is the total size—a cool \~68.95 GB. The couple of Gigs we have shaved are absolutely key for making this all work.
Here is the breakdown of the model weights. We have the famous new n-gram portion, the experts, the active layers, the attention/SSM layers, and the extra space needed for the KV cache:
|Component|Weight (Approx)|Notes|
|:-|:-|:-|
|N-gram / PLE Embedding|\~29.48 GB|The massive lookup table|
|MoE Routed Experts (320)|\~34.89 GB|The main expert slab (pruned from 512)|
|Attention / SSM / Router|\~4.33 GB|Core architecture weights|
|KV Cache|\[TBD\]|Context memory overhead|
Obviously, running this model over SSD would make the speeds notoriously bad. Turning on mmap means that llama.cpp won't actually try to keep the model in RAM at all (it relies on the OS page cache instead), which results in \~2 tok/sec speeds—effectively useless.
The answer is to stick everything in RAM (using --load-mode none). The great thing is that the N-gram section of the model can be streamed over SSD via lazy mmap without this causing much issue—it's a massive lookup table that doesn't require heavy computation.
That's the huge win that allows an MoE model of this size to actually run well.
68.9 GB - 29.48 GB = 39.42 GB.
We just need to cram that 39.42 GB, along with the compute buffers and KV cache, into GPU and system memory, and we are golden—just barely. To do this, we need --lazy-mode on—that's what keeps the N-gram portion in RAM.
After that, it's a matter of fitting as many layers as possible onto the GPU. It's essential to completely fill the GPU as much as can be filled, so that we keep a precious few GBs in system RAM to run the OS. I found that having less than 2 GB left really started to destroy Fedora, but I think you could do better if you dropped the GUI—I just didn't want to in my case.
This leads me to --n-cpu-moe 34. This controls how many layers go to CPU. In my case, this was the exact limit needed to run this with 64k context on the GPU, quantized to Q4. Any more—GPU out of memory. Any less—total system meltdown, as the OS panicked and tried to put everything on the swap. You'll need to play around with this, but that was my exact number.
Settings used:
CUDA0 + --load-mode none --lazy-mode on
--n-cpu-moe 34
-c 65536 -b 512 -ub 128 -t 7 -ngl 48 -fit off -fa on
-ctk q4_0 -ctv q4_0 -kvo --cache-ram 0 --jinja --no-warmup
Results (64k Context, Q4):
I think this is in a somewhat usable state—but Qwen 3.8 27B GSQ IQ3S remains my daily driver; it's able to prompt process 5 times faster, I can fit in the mmproj and MTP layers, and it doesn't seem likely to set my desk on fire. But maybe for really hard tasks, I'll use the next model. It is smarter, it runs at a reasonable speed, and it was a good learning experience.
I'm curious if anyone else is able to get this model or just large MoEs working on a GPU and RAM config similar to mine. LMK. Also, I'm a total noob to this stuff, any advice is appreciated.
(Also, heading off all the obnoxious "why did you quantize the cache - unusable - just get a better computer" ragebait posts. This is a human being writing this post, to help others and just enjoy pushing something to its limits. And in my limited testing, the next model seems much better at pixel art than the 27B version.)
Final Note: If you have a larger pool of system memory, like 64 GB (because you can spend $899 on Amazon on a kit of DDR5 somehow), you would be better served by using this fork of llama.cpp, which has optimized flags for this exact setup and wonderful guides. For me in particular, with my limited hardware, this seemed to work better—their cache kept OOMing unless I turned on mmap—but I think with more system RAM, their setup and guides are optimal.
I am considering dumping my ChatGPT Plus subscription and go full local, but to do so I would first need to reach a decent result for quality (and reasonable speed).
My 4090 fried itself out of nowhere, so I am not stuck with a 3070 until I get something better.
I am kind of suspicious about the claims the companies are doing lately about the dangers of AI and how they are pumping the prices intentionally to either law out the open source or price out the open source, so I want to just go full local even more now.
I have a MSI MAG X670E Tomahawk WiFi which theoretically supports 3 GPUs?
What would you end up with?
p.s. I am ruling out Macs to be open and easier to setup in case I will want to use them for my homelab

Pushed out this new update, hopefully decreases the instances of crashes. I torture tested this one for \~12 hours after my fixes and found no instability. Q4 K XL needs more fine tuning, which I will work on in the future. I am simultaneously juggling this + a legitimate inference engine + finalizing work on a deep research/site builder application I've been working on for about 6 months. After those get pushed to prod I will refocus here. Thanks!
Plug: join the Launch80 discord if you are in to the cutting edge of RDNA4 optimization! There are guys pushing out even better numbers and configurations than mine here on other quants. I think we are starting to get closer to the ceiling on these configurations where the model isnt fully VRAM resident.

It's interesting to see how Dwarkesh has had to come around to the evidence that we are well on our way to creating AGI and even RSI in the last few months, despite historically being very skeptical.
I highly recommend people interested in large language models check out this particular episode, because it dispels a lot of mythology about stuff like plateaus from lack of data etc. For those who thought we were hitting a wall a year ago, it turns out there was a ton of low hanging fruit and the researchers in this episode discuss what that fruit was. They also extrapolate these trends into the future.
It's funny this subreddit is becoming rather skeptical of AI progress, which to put diplomatically, I think is based on a lack of information and too much time on Reddit.
