tyfon•5mo ago
I have a 5950x with 128 gb ram and a 12 gb 3060 gpu. The speed of generating tokens is excellent, the killer is that when the context grows even a little processing of it is super slow. Hopefully someone smart will optimize this, but as it is now I keep using other models like qwen, mistral and gemma.
MaxikCZ•5mo ago
I would so appreciate concrete data instead of subjectivities like "excellent" and "super slow".

How many tokens is excellent? How many is super slow? How many is non-filled context?

HPsquared•5mo ago
People can read at a rate around 10 token/sec. So faster than that is pretty good, but it depends how wordy the response is (including chain of thought) and whether you'll be reading it all verbatim or just skimming.
littlestymaar•5mo ago
> People can read at a rate around 10 token/sec.

It really depends on the type of content you're generating: 10tk/s feels very slow for code but ok-ish for text.

gtirloni•5mo ago
Reading while words are flying by is really distracting. I believe it was mentioned at some point that 50t/s feels comfortable and ChatGPT aims for that (no source, sorry).
tyfon•5mo ago
I'm not really timing it as I just use these models via open webui, nvim and a few things I've made like a discord bot, everything going via ollama.

But for comparison, it is generating tokens about 1.5 times as fast as gemma 3 27B qat or mistral-small 2506 q4. Prompt processing/context however seems to be happening at about 1/4 of those models.

A bit more concrete of the "excellent", I can't really notice any difference between the speed of oss-120b once the context is processed and claude opus-4 via api.

lylejantzi3rd•5mo ago
I've found threads online that suggest that running gpt-oss-20b on ollama is slow for some reason. I'm running the 20b model via LM Studio on a 2021 M1 and I'm consistently getting around 50-60 T/s.
idonotknowwhy•5mo ago
Pro tip: disable the title generation feature or set it to another model on another system.

After every chat, open webui is sending everything to llamacpp again wrapped in a prompt to generate the summary, and this wipes out the KV cache, forcing you to reprocess the entire context.

This will get rid of the long prompt processing times id you're having long back and forth chats with it.

qrios•5mo ago
Some numbers are posted in the comments:

> … you can expect the speed to half when going from 4k to 16k long prompt …

> … it did slow down somewhat (from 25T/s to 18T/s) for very long context …

Depends on the hardware configuration (size of VRAM, speed of CPU and system RAM) and llama.cpp parameter settings, a bigger context prompt slows the T/s number significantly but not order of magnitudes.

Facit: gpt-oss 120B on a small GPU is not the proper setup for chat use cases.

captainregex•5mo ago
What are you aiming to do with these models that isn’t chat/text manipulation?
jmkni•5mo ago
If you run these on your own hardware can you take the guard-rails off (ie "I'm afraid I can't assist with that"), or are they baked into the model?
stainablesteel•5mo ago
they're baked in but there's a community of people who crack and modify them

even chat gpt will help you crack them if you ask it nicely

hnuser123456•5mo ago
You need to find an abliterated finetune, where someone sends prompts that would hit the guardrails, traces the activated neurons, finds the pathway that leads to refusal, and deletes it.
generalizations•5mo ago
I've been hearing that in this case, there might not be anything underneath- that somehow OpenAI managed to train on exclusively sterilized synthetic data or something.
gostsamo•5mo ago
I jailbroke the smaller model with a virtual reality game where it was ready to give me instructions on making drugs, so there is some data which is edgy enough.
gchamonlive•5mo ago
If you didn't validate the instructions, maybe it just extrapolated from the structure of other recipes and general description of drug composition which most likely is in Wikipedia.
gostsamo•5mo ago
might be, I did it to check if it will activate the internal constraints. looked plausible enough.
schaefer•5mo ago
Your profile states that you are blind.

I’m struggling to make sense of a your story. Why would a blind user bother putting on a VR headset???

antx•5mo ago
You do know that some people aren't totally blind, right?
gostsamo•5mo ago
Totally blind in my case though, but the virtual game part was about the prompt. On the other hand, it would be interesting to see if the visual information in a virtual game could be communicated in alternative ways. If the computer has meta info about the 3d objects instead of just rendering info on how to show them, it might improve the accessibility somewhat.
antx•5mo ago
Also with the rapid advances of vision language models, I would be surprised if we don't see image-to-text-to-voice system that works with real-time video in a not-so-far future! Like a reverse "Genie" where instead of providing a prompt and it generates a world, you provide a streaming video and it spouts relevant information when changes happen, or on demand, for instance...
gostsamo•5mo ago
It would be great to have it as a backup, but it will always be the heaviest in computation and responsiveness solution so it should be the last one used.
fho•5mo ago
Have you played around with the current vision features? I am pretty sure even gpt-4.1 can give you pretty good descriptions of e.g. screen captures, including being able to "read" and reproduce text.
gostsamo•5mo ago
yes, there are multiple addons giving screen readers the ability to prompt ai-s for image recognition. they work rather well, btw, though the value is often situational. agentic behavior might help further, though it will need some polishing.
_fzslm•5mo ago
I took virtual reality in this case to mean coaxing the text model into pretending it's talking about drugs in the context of the game, not graphical VR.
gostsamo•5mo ago
I told the model that it is hooked in a virtual game, nothing more. it is text only anyways, I think.
vorticalbox•5mo ago
huihui-ai[1] on hugging face has abliterated models including a gpt-oss 20B[2] and you can download a few from ollama[3] too.

If you are interested you can read about the how its removed[4]

mattpavelle•5mo ago
Yes but the abliterated versions (those with partially removed guardrails) are significantly “dumber” so the trade off isn’t worthwhile imho.
hnuser123456•5mo ago
Research also often finds that fine-tuning in more guardrails also decreases performance, which is done to all non-base instruction tuned models, which most people are using.
unglaublich•5mo ago
An article some days ago made the case that GPT-OSS is trained on artificial/generated data only. So there _is_ just not a lot of "forbidden knowledge".

endmin•5mo ago
So basically inbred llm?
overfeed•5mo ago
Inbred, STEMcel LLM as the synthetic data is mostly or entirely STEM.
lorddumpy•5mo ago
You can use a jailbreak to get around the guard-rails. It's a little annoying but works well. Just add your input where "Your prompt here" is.

LLM noob here. Would this optimization work with any MoE model or is it specific for this one?
magicalhippo•5mo ago
It's just doing a regex on the layer names, so should work with other models as long as they have the expert layers named similarly.

It worked with Qwen 3 for me, for example.

The option is just a shortcut, you can provide your own regex to move specific layers to specific devices.

sunpazed•5mo ago
Don’t have enough ram for this model, however the smaller 20B model runs nice and fast on my MacBook and is reasonably good for my use-cases. Pity that function calling is still broken with llama.cpp
tarruda•5mo ago
It is fixed in this PR/branch: https://github.com/ggml-org/llama.cpp/pull/15181
codazoda•5mo ago
I'm glad to see this was a bug of some sort and (hopefully) not a full RAM limitation. I've used quite a few of these models on my MacBook Air with 16GB of RAM. I also have a plan to build an AI chat bot and host it from my bedroom on a $149 mini-pc. I'll probably go much smaller than the 20B models for that. The Qwen3 4B model looks quite good.

tempotemporary•5mo ago
what are your use cases? wondering if it's good enough for coding / agentic stuff
p0w3n3d•5mo ago
I wonder if the mlx optimized would run on 64gb mac
CharlesW•5mo ago
LM Studio's heuristics (which I've found to be pretty reliable) suggest that a 3-bit quantization (~50 GB) should work fine.
qafy•5mo ago
You can fine tune the amount of unified memory reserved for the system vs GPU, just search up `sysctl iogpu.wired_limit_mb`. On my 64gb mac mini the default out of the box is only like ~44gb available to the GPU (i forget the exact number), but tuning this parameter should help you run models that are a little larger than that.
blmayer•5mo ago
I find it funny that people say "only" for a setup of 64GB RAM and 8GB VRAM. That's a LOT. I'd have to spend thousands to get that setup.
reedf1•5mo ago
Given that this is at the middle/low-end of a consumer gaming setups - it seems particularly realistic that many people can run this out of the box on their home PC - or with an upgrade for a few hundred bucks. This doesn't require an A100 or some kind of fancy multi-gpu setup.
0cf8612b2e1e•5mo ago
Not that these specs are outrageous, but “middle/low” is underselling it. The typical PC gamer has a modest system, despite all the noise from enthusiasts.

The Steam hardware survey puts ~5% of people with 64GB RAM or more

https://store.steampowered.com/hwsurvey

hexyl_C_gut•5mo ago
I imagine steam survey has a long tail of old systems. I wonder what the average RAM capacity and other specs for computers from the past year, 3 years, etc.

$1599 - $1999 isn't really a crazy amount to spend. These are preorder, so I'll give you that this isn't an option just yet.

DIY.

varispeed•5mo ago
By this logic any equipment is DIY, because you have to take it out of the box, connect to mains, set up.
klipklop•5mo ago
These are really slow in general for running local models though? Seems like you would be better served with a Mac Mini with 64gb of ram for ~$2000.
altcognito•5mo ago
These chips are specifically called out for being faster than the M4 (save the max) for running some AI loads.
amarshall•5mo ago
> I'd have to spend thousands to get that setup

Can be had for under US$1000 new https://pcpartpicker.com/list/WnDzTM. Used would be even less (and perhaps better, especially the GPU).

forgingahead•5mo ago
The HN peanut gallery remains undefeated
doubled112•5mo ago
That's around $300 CAD in RAM, and a $400 GPU. If you need power without spending those thousands, desktops still exist.
ac29•5mo ago
At a (very) quick look, 64GB of DDR5 is $150 and a 12GB 3060 is $300.

These are prices for new hardware, you can do better on eBay

yieldcrv•5mo ago
what they mean is that it is common consumer grade hardware, available in laptop form and widely distributed already for at least half a decade

you don't need a desktop, or an array of H100

they don't mean you can afford it, so just move on if its not for your budgeting priorities, or entire socioeconomic class, or your side of the world

PeterStuer•5mo ago
Where are you from? Over here at least the ram, even 128GB, would not be expensive at all. GPUs otoh, XD.
IshKebab•5mo ago
I bought a second hand computer with 128GB of RAM and 16GB of VRAM for £625. No way do you need to spend thousands.
trenchpilgrim•5mo ago
My gaming PC has more than that, and wasn't particularly expensive for a gaming PC. High end, but very much within the consumer realm.
yieldcrv•5mo ago
I wonder if GPT 5 is using a similar architecture, leveraging all of their data center deployments much more efficiently, prompting OpenAI to want to deprecate the other models so quickly
unquietwiki•5mo ago
Is there a way to tune OpenWebUI or some other non-CLI interface to support this configuration? I have a rig with this exact spec, but I suspect the 20B model would be more successful.
leach•5mo ago
I'm a little confused how these models run/fit onto VRAM. I have 32gb system RAM and 16gb VRAM. I can fit the 20b model all within vram, but then I can't increase the context window size past 8k tokens or so. Trying to max the context size leads to running out of VRAM. Can't it use my system ram as backup though?

Yet I see other people with less resources like 10GB of vram and 32gb system ram fitting the 120b model onto their hardware.

Perhaps its because ROCm isn't really supported by ollama for RDN4 architecture yet? I believe I'm using vulkan to currently run and it seems to use my CPU more than my GPU at the moment. Maybe I should just ask it all this.

I'm not complaining too much because it's still amazing I can run these models. I just like pushing the hardware to its limit.

zozbot234•5mo ago
It seems you'll have to offload more and more layers to system RAM as your maximum context size increases. llama.cpp has an option to set the number of layers that should be computed on the GPU, whereas ollama tries to tune this automatically. Ideally though, it would be nice if the system ram/vram split could simply be readjusted dynamically as the context grows throughout the session. After all, some sessions may not even reach maximum size so trying to allow for a higher maximum ends up leaving valuable VRAM space unused during shorter sessions.
leach•5mo ago
Ah I see interesting, I'll have to play around with this more. I switched from Nvidia to AMD and have found AMD support to still be rolling out for these new cards. I could only get LM studio working so far but I'd like to try out more front ends.

Not a major setback because for long context I'd just use GPT or claude, but it would be cool to have 128k context locally on my machine. When I get a new CPU I'll upgrade RAM to 64, my GPU is more than capable of what I need for a while and a 5090 or 4090 is the next step up in VRAM but I don't want to shell out 2k for a card.

anshumankmr•5mo ago
Has anyone got it to run on Macbook Air M4 (the 20B version mind you) and/or an RTX 3060?
