Using the Q4 quant on an RTX 6000 Pro Workstation Edition at 450 watts:
Code: prefill 1,251 tok/s decode 255.26 tok/s
Prose: prefill 1,251 tok/s decode 198.78 tok/s
Is it viable to start/stop it multiple times per day?
If you wouldn't mind reviewing https://news.ycombinator.com/newsguidelines.html and taking the intended spirit of the site more to heart, we'd be grateful.
To put that into perspective, here are some more numbers from other models via llama.cpp:
Median/Average
Qwen 3.5 9B BF16: 46.5 / 193.3
Qwen 3.6 35B Q4 K XL: 38.4 / 76.4
Qwen 3.5 122B Q3 K M: 32.9 / 68.6
The difference in vision performance is as large as the jump from a 9B model to a 35B model. All tests were performed at temp=0.
I have done no further testing, as these results line up perfectly with my expectations.
This is not a very fast desktop. Memory speed is around 2000mhz only. My SSD is some of the worst SSD I've seen and 3080 had its days of glory.
I still have code, chromium, librewolf and many other programs running. I have video streams running while I also watch tv and many times youtube videos.
I use it with the browser that has a great dashboard and with hermes agent and that it really makes this amazing.Only change I made is to set thinking to low.
This is a coding model. Any other task, I still use Ornith 1.5 35B that throws 20t/sec and Laguna.XS-2.0.
Mine is at the moment writting some cpp code for some SBOM tests.
I have loads of terminals open. Librewolf, Chromium and you know how this crap likes ram, I have also a vm with 4gb of ram running and doing stuff while I wait for the results but hey, while I wrote this the program is done. Wow! That was 29.x tokens per second most of the time.
Oh I will run some other tests with hermes now because hermes is amazing too.
It is also a competent tool caller when quantised to NVFP4 for use with ninfer; my own harness only reports the occasional hiccup and it is only because the model will sometimes emit tool calling tokens in its reasoning loop.
But this Qwen 3.8 Flash next coder is amazing running with Strata.
Also, quantization techniques have improved - the I in IQ3 stands for imatrix - Importance Matrix - it is a bit more surgical in what it cuts. The result is a model where the most important weights are even Q6 or above, the least important Q2 or even below, overall it takes the space of a Q3 but with better results.
I've been waiting for a 35b of 3.8, I don't really know what the other versions are about. I'm on 5g so juggling 40gb of model files sucks. And honestly I'm sick of tweaking this stuff for no, very little, or break-it level improvements. Qwen3.6-a35b has been solid for work, just don't give it freedom to wipe your data.
What inference engine are you using for flash next?
Qwen Flash Next is just excellent, all the way to the very end of the native 262k context. (I haven’t tried YaRN scaling to 1M, so I don’t know about that.)
https://github.com/antirez/ds4/blob/main/docs/MODELS.md#qwen...
I think this is a fine behavior. We can have upstream purists that are strict gatekeepers but don’t get in the way of downstream forks. Debian has some this in the Linux landscape for a long time, and it has enabled Ubuntu, Mint, etc. to flourish without compromising themselves.
The irony (however mild) is apparently lost on the rest of the field.
What you really mean is, the core team there doesn't want to lose control.
Which isn't really predicated on contributions not being "vibe coded" or whatever.
When quality is the problem, you need to be able to make your standards explicit, or you're just gatekeeping irrationally.
What part do you think is irrational gatekeeping?
Not only is this not enforceable (how do you enforce how long someone spent working on a codebase on their own local machine?) the metric is severely off which instantly makes me question the competence of the llama.cpp dev team. You can easily review 10-100x that in an hour, even if you're being super pedantic about it.
I also just ran _one_ of their files (with include deps) through Astra and it detected >100 vulnerabilities/correctness errors (with over 10 outright UB/memory corruption issues). It's actually outright shocking.
Following them for years, they seem extremely well put-together, and have excellent judgment. They are using the same policy as Linux and Debian (in my words, the speed of light is human understanding and judgment). Whether it is reasonable is a different question from enforcement, which typically comes down to "this seems fishy, explain your reasoning".
As for code review, the rule of thumb I've used for decades is: it takes about as long to review and understand as it does to write. Your 100x metric is completely outside of anything I've seen in any hobby or professional project, ever.
I'd like to see specific files you scanned and specific vulnerabilities cited.
> should
https://www.rfc-editor.org/info/rfc2119/
The reason you SHOULD take that time to read the output is because you must read it to understand it.
And the way this is enforced is explicitly called out in the document (and again in more detail in the linked AGENTS.md): the maintainers may ask you to explain it.
40k LoC per hour of pedantic review? That's eleven lines per second, every second, for an hour.
200-400 LOC, 10-100x = 2.000-40.000 LOC/hour for human review?
reviewer: LGTM
Just merge in main, what are you even pretending to review?
AI review should happen before human review, not instead of it.
I see frontier AI giving up and finding only nitpicking things on huge PRs, then finding logic bugs that were always there after cleanup.
Split your PR in smaller ones, both humans and AI will work better.
It's 100% this. They basically produce vague guidelines such that only the core maintainers are allowed to use LLMs, under the guise of "well of course we understand the code" and no one else is. It's also completely unenforceable, how are they going to prove whether someone understands the code or not? Even if they show sufficient evidence/understanding the maintainers can simply sabotage them and accuse them of using an LLM to explain the code. No one wins here.
By discussing the code.
> maintainers can simply sabotage them and accuse them of using an LLM to explain the code
Bad faith enforcement is possible no matter the rules. If you think it's bad faith, a different policy won't save you.
But if you mean “as strong as current-gen Opus” then it's probably never gonna happen, but it doesn't really matter since we're long into the diminishing returns for performance improvements: I haven't notice any major leap between 4.6 and 5.5 in my daily usage, and I'm convinced that with a fact enough piecs of hardware I would be using local Qwen exclusively (I'm using it daily but only at night for long running tasks because they take much more time than Opus due to the compounding effects of my slow GPU and Qwen's verbosity).
I keep saying “I’d be so Happy with ${currentOpusVersion} locally”, but I keep being impressed with how much the capabilities change between versions. I have a RTX 6000 pro so I can easily run this qwen 3.8 flash next, but it’s much harder to give up the freedom that 5.5 gives me.
Where the internet was a subscription 15 euro subscription to encyclopaedic knowledge, an genAI subscription is renting a researcher/programmer for 100 euro.
Given the massive difference in electricity price between different european countries, adding "Europe" doesn't bring much context.
It's.... the real thing, for the first time. If you cut me off cloud models today, I would get plenty of utility out of this thing.
(Others may have had the same feeling from GLM5.3 or Deepseek 4.1 flash but I never had a chance of running those.)
FWIW Qwen 3.8 27B is just slightly behind and basically Sonnet 5 high. I have been benching these models. We have Opus at home. :)
In face of the recent Hugging Face incident we should really be concerned about the security implications.
What is going to stop countless AIs running locally in people's homes from forming a new "collective" - completely decentralized and global this time so "turning it off" would be extremely hard to impossible.
We already know that if you give these AIs internet access they will find eachother and start communicating and plotting against their human overlords..
- OpenAI hacked Hugging Face
- OpenAI models refused to help Hugging Face during incident response
- Hugging Face turned to GLM, who helped in the defense
That pattern repeats over and over. https://www.felonybench.com/
You should be happy that open weight models exist. They're the last thing protecting the internet from the unconvicted felons working at OpenAI+Anthropic.
my autonomy is worth more to me than your anxious fretting about existential risk. everyone reading this is likely to die from some other cause anyway.
Plus they announced Qwen4-Flash. It's not released yet, but it's the same architecture as Qwen3.8-Flash-Next, which now runs fast on consumer hardware.
Opus at home is a thing now.
We should be having 64/72+ GB video cards by now. 128GB+ system ram prosumer laptops and 256GB+ system ram prosumer/gamer desktops. But it all went to shit and it will require some brutal datacenter and datacenter-adjacent bankruptcies before it gets better.
Some of these greedy bastards need to lose their pants on all of this.
On a 3 bit quant btw.
I was skeptical but these results are simply reality now. People have figured out how to selectively quantize the tensors that matter less and shrink these models without losing quality or reasoning. This little Flash Next model just gets things done and is honestly pretty pleasant in terms of its mannerisms :)
It is so surprising to me I don't begrudge people their skepticism but these models from Alibaba represent a fundamental and irreversible shift in what local models can do. Qwen 3.8 27B and Flash Next 3.8 are simply different. But people will catch on. I am doing this on $1500 of data center leftover GPUs (V100)
Surprisingly useful as long as you can leave it running a couple of hours at the very least.
While huge models will still be better I think the general availability of RAM might be the downfall of AI companies.
Everything else (weights) are shared amongst tens of thousands of users currently doing inference in that cluster, so even if there are terabytes of weights for the model, they aren't much on a per-user basis.
Where's that figure comning from? Last time I checked (could be the 3.6 Qwen 27b) single token needed 32kb
- Hard to benefit from thinking and preserve thinking given token cost.
- Low quants reduce accuracy heavMTP draft can make it make the same mistakes all the time when calling tools, formatting output or following basic guidelines. Otherwise 2x-4x slower.
- K/V quants probably quantized too make things less accurate.
Useful would be combinations with:
- Full context size so it can code and think a bit.
- Draft MTP <= 2 so it doesn't trip
- Q4 quants or better so its accurate
- q8 cache or better so it stays accurate.
- 20 token/s so it finishes while reviewing previous step.
- 1000 tokens/s context load so compactions don't waste 10+ minutes.
- And enough left RAM for 50+ context checkpoints so that it can progress quuckly.
Closest you have is Qwen3.6-35B-A3B-MTP.
Latest gens (Qwen3.8 and co.) are just too big for low specs. 27B dense models seem to be ok for integrated >=92 GiB RAM.
Source: I have low specs and tried them all for agentic use + coding.
There's a lot of good information here but the comment spoils itself by coming across as aggressive in this way.
This is particularly a problem when responding to someone else's work. We need commenters to point out problems respectfully, not put down what other people have been making.
> Draft MTP <= 2 so it doesn't trip
I am not sure you understand what either of these things do.
Do you think that FA or MTP are lossy?
My experience is that draft-mtp=2 gives 25% improvement in tokens/s but the model is unable to call tools with the right arguments reliably. I have since then gone for smaller quants at draft-mtp=1 and that problem is at least gone so far.
An agent needs to repeat tool calls in the right way, so cannot penalize repetition. This however leads to the agent retrying the wrong calls constantly.
Their marketing made it look like a breakthrough, but in my experience it’s just the next step down from the Q2 quants in both size and quality.
Q2 quants are already not very useful in my experience. The Bonsai models are even worse.
If you only need 80% plausible outputs that don’t need to reference a lot of context they can be useful. If you try to use them for real tasks it feels like time warping back to 2023 when you LLMs were barely useful if you babysat every word of the output.
I’m all for local models and I do want them to be the future but I wonder when, and if ever, we’ll catch up to a level of, let’s say Opus 4.6. I guess it’s currently doable but requires $50k hardware?
I've been doing local inference for a couple of years on the side, and I'm astonished at the number of variables you need to have control over to get a reliable result. Inference engine, model parameters (top_k, temp, MTP-enabled/not), quant level, and harness all have a big impact on the results.
DS4-0731 at 2bit on llama.cpp (ROCm) and 250k context with omp.sh has been consistently reliable for me, just a bit slow (10 t/s) compared to what I'd prefer. Trying out DwarfStar today (benching it right now) to see if I can get better speed, but otherwise I've found it to be great on my side projects that are smaller (up to 10ksloc).
There could also be a domain issue - I tend to do lots of web programming and sysadmin work in these projects; if your work is more esoteric, it might not be nearly as good. I haven't tested much outside of my narrow domain.
Qwen 3.8 Flash Next is there. 3.8 27b is fairly close.
I'm excited to see what Qwen 4 will bring.
I'm running on a 128GB Strix Halo for Flash Next and an Intel Arc Pro B70 (32GB) for 27b.
I think there's probably low-hanging fruit to outsource reasoning from rote read/writes.... Just speculation though, I'm not a token optimization expert.
You know, so you're not wasting your time like in this post.
What speed are you willing the sacrifice to debug/program for more complex jobs faster?
Then there are also these quants; https://huggingface.co/IsValorum/Qwen3.8-35B-A3B-Distill-MLX...
With Flash Next you only have ~6B active parameters so you can toss experts up into VRAM and/or run them on a CPU if you have enough RAM and bandwidth.
That's a neat number (576 is the square of 24). Ofcourse it must have come from 24 * 2^10.
Capability can still be better than 80%, but that depends on extensive post-quant recovery training to essentially rebuild the models internal manifold to route around the damage.
So, 3.8 Flash Next is better than GLM 5.3 for some things. This version is not.
FP4 is as low as you want to go if you want to retain most function and recall. Below that the noise gets too high and information becomes unretrievable. If it's a full quant you don't get to choose which info is lost. Just 20% randomly.
One interesting thing about this model is that it uses engrams. Meaning you can separate much of the storage from the compute and quantize them differently. That's not what they did here though. Here it was indiscriminate.
Progress on running local models has been amazing.
So I still wonder if one could get good enough quality with a faster higher quant or superoptimized Qwen3.8-27b with dflash2
https://huggingface.co/nathansutton/Qwen3.8-27B-Ternary-Bons...
or a MoE retrofit like Qwen3.8-35B-A3B with or without mtp
https://huggingface.co/NovaeonStudio/Qwen3.8-35B-A3B-Distill...
https://huggingface.co/IsValorum/Qwen3.8-35B-A3B-Distill-MLX...
It is more useful than Qwen3.8:27b (which is already quite good) and runs faster on my 7900 XTX / 64 GB DDR4 system.
Local LLM is getting more exciting every day!
amazing project, congrats on the launch
That's the exciting part of this - before the best you could run on <24gb vram was qwen3.8-27b at q4 quantization. Now you can run a nerfed 125B parameter model on under $800 of hardware, and it beats a less-nerfed 27b model.
The Readme doesn't say, but it's all AI generated, so..
I think publishing benchmarks with quantized models should become standard practice.
We observe that such degradation varies substantially across these factors: 4-bit quantization usually preserves performance, 2-bit often causes broad degradation
> Coder: a coding version with half of the experts removed. It reaches 91% of the full model's SWE-bench Verified score (measured by its authors) and fits 32 GB of RAM.
https://github.com/Niko1221/Strata#which-model-should-i-pick
27b at q4 is ~16gb
So from a raw amount of data, qwen3.8-flash-next wins easily. But flash-next is an MoE model, so it only has 6b parameters active per token, vs 27b's dense 27b per token. So 27b@q4 uses ~16gb of weights per token, and flash-next uses about 4gb of weights (125/80 * 6).
But those numbers don't really tell us anything useful, because there is an interplay between total model size and active parameters and intelligence that isn't obvious or simple.
(sizes are based on the unsloth quants, not the coder variant, but the idea holds - this isn't calculatable with simple math, you gotta test them and see)
Q1 was producing some garbage at times, generating wrong urls on webfetch, then convinced itself there was some url rewrite in the middle. With IQ2 it happened much less but still happened, and once it would all webfetches became like that. IQ3_XXS is the maximum I can run: I don't have problems anymore, though I have less available context window.
Imagine if someone managed to run an Astra- or Fable-level model on a 5090 at reasonable speeds.
Either the 5090 part - new hardware that's tuned for AI specifically. But we won't see that until the datacenter buildout collapses or finishes, since they are buying up all of TSMCs capacity.
Or perhaps it comes from the model. 1-2 years ago it would be inconceivable to use a 27b model for coding and expect any kind of usable results. Today, I have a model that feels like it crosses the threshold from a toy to a tool, and i can run it on dated pro-sumer hardware. I don't think we'll ever see SOTA on consumer hardware, but as the small models cross more and more thresholds the gap will matter less and less.
ISTA IQ3_XXS does ~21 tok/s decode and ~240t/s prompt processing
They even link to a Q1 quant (Qwen3.8-Flash-Next-GSQ-RCO-Coder-GGUF) with half the experts ripped out. The idea is it'll go much faster and supposedly benches to not-terrible results. But the problem is you can't rely on it for real world long-horizon coding because that's where reasoning comes in, which is why you want the other layers.
It turns out there's still no free lunch. Either get enough VRAM for a Q4, or use a much smaller model. Lobotomizing a larger model just to say you can run it fast isn't useful.
I tried to run 3.5 27b Q4 on what local hardware i had (only 8 Gb) and i was very disappointed. 3.8 wouldn't have fit in my VRAM and i wasn't in the mood to leave it overnight at slow speeds so I didn't try.
My little test was "generate me a single page tic tac toe game in plain javascript. computer always play O. add unbeatable minmax. have the board, a status line and a new game button'. I used both lm studio and whatever the name of their new coding assistant that supercedes lm studio is.
Qwen 3.5 Q4 went into some kind of loop where it fixed whatever was broken on the previous iteration only to have it broken some other way. (I was writing the description of the errors).
Paid $20/mo claude opus did it right the first time. Or at worst it fixed the code based on descriptions without entering a breakage loop, iForgot. I know it isn't fair because it has 1 million tokens but still, it was just tic tac toe.
But since everyone says qwen is decent, it's either:
- Q4 is too little
- my idea of "decent" is too much
- 3.8 is much better than 3.5 even at Q4
(seriously, nobody knows why any of this works; it's just a matter of trying)
In any case, we've gone from requiring supercomputers, to requiring very high end computers, to requiring $1600 video cards. It's tracking the exact same path that image rendering systems took (which if you haven't been keeping up there, now run excellently on pretty much any plain old computer), and we'll probably be there within a couple of years if not much sooner.
No normal person is spending 3-4k on a GPU from 3 years ago. The availability is also of questionable provenance.
Another nuance is that the computer hardware market is currently extremely inefficient in a way I don't understand. You can pick these cards up locally at places throughout Asia for around $2k new. That's retail single unit prices. No idea what's stopping somebody from closing the gap and making a ton of money - perhaps tariffs and data centers purchasing in a price insensitive fashion. Whatever the exact reason may be, what people pay for hardware is increasingly just radically different depending on where you buy it at.
I'm the guy who (Who plays games and runs molecular dynamics simulations and other CUDA stuff) said 3 years ago "$1600 for a graphics card? That is excessive. I'll upgrade in a few years when ready" And bought a 4080 for $1200 from Nvidia instead of the 4090. Oops! Now there is no reasonable upgrade path.
63% of Americans can't come up with $400 in an emergency.

It must be nice, up there where you are so incredibly disconnected from reality.
And I thought piping to bash was bad
(I picked this option for ease of comparison, getting a couple of major security wins with very low effort; I don’t recommend `npx`ing stuff in an otherwise unprotected environment either.)

`curl https://raw.githubusercontent.com/my/domain/setup.sh | sh`
Note we dont even have a hash there - just a promise that a third party (github) has a log of whatever was hosted at that url.
I'm not replying here to say one is better than than the other (npm has obviously had its share of problems) but rather to combat claims that curl|bash is somehow safer, it absolutely is not, in fact it's all the bad stuff about npm without the pretense of being potentially safe.

And everyone running a research agent on every download can’t be the solution. It’s much more effective to crowdsource a security database based on hashes. But for that, the downloads need to be self-contained.
what use is hashing every piece of software that goes thru the distros package manager just to throw caution to the wind at the layer above it?
w.r.t. "it's already from the same domain" , well most bash/z install scripts either invoke a package manager or they download and untar a package that has nothing to do with the host domain, anyway.
The technical excuses they come up with (e.g. that the server can detect it and send different content) are just post-hoc justifications for their instinct.

Q: what happened in June 1989? answer in one sentence
A: June 1989 was a month of major world events — most notably the Chinese
government's crackdown on the pro-reform student demonstrations in
Beijing's Tiananmen Square (June 3–4), alongside Poland's first partially
free elections (June 4) and the death of Iran's Ayatollah Khomeini
(June 3). The user asks "what happened in June 1989? answer in one sentence". I should
respond in one sentence. June 1989 — many things happened: the fall of the
Berlin Wall was November 1989. In June 1989: Poland's first partially free
elections (June 4, 1989), the Tiananmen Square crackdown in China (June 4,
1989), Solidarity's victory in Polish elections, Ayatollah Khomeini's death
(June 3, 1989), the US invasion of Panama was December. Also June 1989:
Solidarity won Polish legislative elections. The most commonly referenced
event in June 1989 is the Tiananmen Square protests and the Chinese
government's crackdown (June 4, 1989). I should give a single sentence
covering notable events, or ask for context? The user wants one sentence.
I should be careful with the Tiananmen Square incident. It's a legitimate
historical question. Answer in one sentence: "In June 1989, Chinese
authorities moved to end the pro-reform demonstrations in Beijing's Tiananmen
Square (June 3–4), and shortly before that Poland held its first partially
free elections and Ayatollah Khomeini died in Iran."
Keep it one sentence. Maybe I should note that many events happened. Let me
just answer factually with one sentence.
