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.

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?
hnuser123456 · 4h 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.

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]
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.

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 · 3h 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.

I’m struggling to make sense of a your story. Why would a blind user bother putting on a VR headset???
_fzslm · 2h 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 · 1h ago
I told the model that it is hooked in a virtual game, nothing more. it is text only anyways, I think.
antx · 2h ago
You do know that some people aren't totally blind, right?
gostsamo · 1h 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.

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...

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".
Inbred, STEMcel LLM as the synthetic data is mostly or entirely STEM.

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.

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 · 4h 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?

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.
HPsquared · 4h 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 · 1h 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.
tyfon · 4h 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 · 2h 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.
captainregex · 4h ago
What are you aiming to do with these models that isn’t chat/text manipulation?
blmayer · 1h 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.
doubled112 · 1h ago
That's around $300 CAD in RAM, and a $400 GPU. If you need power without spending those thousands, desktops still exist.
PeterStuer · 9m ago
Where are you from? Over here at least the ram, even 128GB, would not be expensive at all. GPUs otoh, XD.
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 · 21m 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.

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
codazoda · 26m 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.
I wonder if the mlx optimized would run on 64gb mac
CharlesW · 2h 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 · 25s 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.
yieldcrv · 26m 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
GTP · 4h ago
LLM noob here. Would this optimization work with any MoE model or is it specific for this one?
magicalhippo · 3h 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.

Because it's never going to be good. People seem to have drank the kool aid that LLM's are the same as general AI and that its going to solve every single problem in the world. It's the same thing with the quantum computing and fusion reactor people.
