I recently picked up a Threadripper 3960x, 256GB DDR4 and RTX2080ti 11GB running Debian 13 and open web-ui w/ ollama.

It runs well, not much difference to Claude etc but still learning the ropes and how to get the best out of it and local llms in general. Having tonnes of memory is nice for switching out models in ollama quickly since everything stays in cache.

The GPU memory is the weak point though so I'm mostly using models up to 18b parameters that can fit in the vram.

Real-world workflows? I'm all for local LLM, tinker with it all the time, but for productive coding use no local LLM approaches cloud and it's not even close. There's no magic trick or combination of pieces, it just turns out that a quarter million dollars worth of H200s is just much, much better than anything a normal person could possibly deploy at home. Give it time, we'll get there, but not anytime soon.

I thought you would just use another computer in your house for the flows? My development flow takes a lot of RAM (and yes I can run it minimally editing in the terminal with language servers turned off), so I wouldn't consider running the local LLM on the same computer.

It's not about which of your computers you run it on, it's about the relative capability of any system you're likely to own vs. what a cloud provider can do. The difference is hilarious - probably 100x. Knowing that, unless you have good reasons (and experimenting/playing around IS a good reason) - not many people would choose to actually base their everyday workflow on an all-local setup.

It's sort of like doing all your work on an 80386. Can it be made to work? Probably. Are you going to learn a whole lot making it work? Without a doubt! Are you going to be the fastest dev on the team? No.

I got a personal Mac Studio M4 Max with 128GB RAM for a silent, relatively power-efficient yet powerful home server. It runs Ollama + Open WebUI with GPT-OSS 120b as well as GLM4.5-Air (default quantisations). I rarely ever use ChatGPT anymore. Love that all data stays at home. I connect remotely only via VPN (my phone enables this automatically via Tasker). I'm 50% brainstorming ideas with it, asking critical questi…

I like your method of adding TODOs in your code, then using a model - I am going to try that. I only have a 32G M2 Mac so I have to use Ollama Cloud to run some of the larger models but that said I am surprised by what I can do ‘all local’ and it really is magical running all on my own hardware, when I can.

gpt-oss-120b is amazing. I created a RAG agent to hold most of GCP documentation (separate download, parsing, chunking, etc). ChatGPT finished a 50 question quiz in 6 min with a score of 46 / 50. gpt-oss-120b took over an hour but got 47 / 50. All the other local LLMs I tried were small and performed way worse, like less than 50% correct. I ran this on an i7 with 64gb of RAM and an old nvidia card with 8g of vram. ED…

What do you use to run gpt-oss here? ollama, vLLM, etc

Not parent, but frequent user of GPT-OSS, tried all different ways of running it. Choice goes something like this:

- Need batching + highest total throughoutput? vLLM, complicated to deploy and install though, need special versions for top performance with GPT-OSS

- Easiest to manage + fast enough: llama.cpp, easier to deploy as well (just a binary) and super fast, getting ~260 tok/s on a RTX Pro 6000 for the 20B version

- Easiest for people not used to running shell commands or need a GUI and don't care much for performance: Ollama

Then if you really wanna go fast, try to get TensorRT running on your setup, and I think that's pretty much the fastest GPT-OSS can go currently.

For anyone who wants to see some real workstations that do this, you may want to check out Alex Ziskind's channel on YouTube: https://www.youtube.com/@AZisk At this point, pretty much all he does is review workstations for running LLM's and other machine-learning adjacent tasks. I'm not his target demographic, but because I'm a dev, his videos are constantly recommended to me on YouTube. He's a good presenter and his…

His reviews are very amateurish and slapdash. He has no test methodology and just throws together random datapoints that can't be compared to anything. In his Pro 6000 video he compares it with an M3 128GB with empty context. Then he runs a large context (a first for him!) on the 6000 and notes how long prompt processing takes, and never mentions the M3 again!

Seems pretty spot on for what you'd expect from YouTube developers, most of the channels are like that to be honest. Something about "developer" + "youtube" that just seems to spawn low effort content that tries to create drama rather than fair replacements for blog posts that teach you something.

you can run the 120b model on an 8GB GPU? or are you running this on CPU with the 64GB RAM? I'm about to try this out lol The 20b model is not great, so I'm hoping 120b is the golden ticket.

I have in many cases had better results with the 20b model, over the 120b model. Mostly because it is faster and I can iterate prompts quicker to choerce it to follow instructions.

> had better results with the 20b model, over the 120b model

The difference of quality and accuracy of the responses between the two is vastly different though, if tok/s isn't your biggest priority, especially when using reasoning_effort "high". 20B works great for small-ish text summarization and title generation, but for even moderately difficult programming tasks, 20B fails repeatedly while 120B gets it right on the first try.

For new folks, you can get a local code agent running on your Mac like this: 1. $ npm install -g @openai/codex 2. $ brew install ollama; ollama serve 3. $ ollama pull gpt-oss:20b 4. $ codex --oss -m gpt-oss:20b This runs locally without Internet. Idk if there’s telemetry for codex, but you should be able to turn that off if so. You need an M1 Mac or better with at least 24GB of GPU memory. The model is pretty big, ab…

I've been really impressed by OpenCode [0]. The limitations of all the frontier TUI is removed and it is feature complete and performant compared to Codex or Claude Code. [0] https://opencode.ai/

> OpenCode will be available on desktop soon

Anyone happen to know what that means exactly? The install instructions at the top seems to indicate it already is available on desktop?

Interesting. Is there a way to load this into Ollama? Doing things in browser is a cool flex, but my interest is specifically in privacy respecting LLMs -- my goal is to run the most powerful one I can on my personal machine, with the end goal being those little queries I used to send to "the cloud" can be done offline, privately.

Yes, the granite 4 models are on ollama: https://ollama.com/library/granite4 > but my interest is specifically in privacy respecting LLMs -- my goal is to run the most powerful one I can on my personal machine The HF Spaces demo for granite 4 nano does run on your local machine, using Transformers.js and ONNX.

Thanks for this pointer and explanation, I appreciate it.

Also my "dev enviornment" is vi -- I come from infosec (so basically a glorified sysadmin) so I'm mostly making little bash and python scripts, so I'm learning a lot of new things about software engineering as I explore this space :-)

Edit: Hey which of the models on that page were you referring to? I'm grabbing one now that's apparently double digit GB? Or were you saying they're not CPU/ram intensive but still a bit big?

I sometimes still code with a local LLM but can't imagine doing it on a laptop. I have a server that has GPUs and runs llama.cpp behind llama-swap (letting me switch between models quickly). The best local coding setup I've been able to do so far is using Aider with gpt-oss-120b. I guess you could get a Ryzen AI Max+ with 128GB RAM to try and do that locally but non-nVidia hardware is incredibly slow for coding usage…

on what hardware you manate to run gpt-oss-120b locally?
