Yes. Llama.cpp + Qwen3.6-35b (MTP) + OpenCode is quite capable and runs on a single RTX 3090 and is faster than most cloud models. Quality is like running edge models from 8-12 months ago. Setup details at https://github.com/pierotofy/LocalCodingLLM/
Do you do your dev work on the windows machine (referenced in the docs), or do you remotely access it from a separate machine? I ask because I have a RTX 3090 kicking around in a gaming desktop, but I don't use it for any dev work (I use a Macbook Pro).

For me the distinction is that your rice only needs to be edible once, while your code may need to last for decades. Using AI to code anything I could comfortably throw away if needed is a lot less fraught than letting it make choices that I and anybody who inherits the code is gonna have to live with, especially if by outsourcing those choices I reduce my understanding of the implications of those choices.
For example you can just tell it to make a website for a business with a webshop and it'll just generate thousands of lines of code and you have no control over anything. Or you can spend hours/days writing the specification and then have it generate it.
Or you can do what I do and work iteratively one feature at a time making sure everything is exactly the way you want it. I generally solve the problem myself then tell it what to do, or if I'm not sure what the best solution is I might discuss with the AI until we agree on a plan and then have it execute it. Often this leads to me learning useful things, like it will suggest a tool/feature that I didn't know about that's perfect for my usecase or it will identify a problem in my plan that I wouldn't have found until after spending hours on the implementation.
I've always been very detail oriented and I care a lot about code quality, I want my solutions to be clean, consistent and as simple as possible while solving the problem. To me, AI tools let me do that more quickly and better, it's not a compromise it's just flat out better in every dimension. It's about how you use it.
A lot of people seem to think that it's a binary choice, either hand craft a high quality bespoke solution or just vibe code a pile of trash. There's a whole spectrum in between those two, and I think there's a sweet spot where you still maintain control and understanding, it's just much faster and the result is actually better because it's not just you and the knowledge in your brain it's also the AI that practically knows everything - it will teach you things and suggest solutions you wouldn't have thought about, it makes you a better developer. It's a force multiplier and the smarter you are the better you will be at using it.
It's not a replacement it's an enhancement. It's like imagine a developer with Google vs one without, obviously the one with Google will be better because they have access to more information. The AI is like automatic google that just googles everything all the time, things you wouldn't have even thought to Google or things you couldn't possibly formulate a good search term for. With AI you can just show it a screenshot or describe an issue in detail and get a really solid answer a lot of the time. It's like having an expert on standby all the time, sure it's sometimes wrong but most of the time it's not and if you're smart you'll recognize when it isn't.
I'd say anyone who isn't using AI today aren't using their full potential. I don't see how anyone could possibly perform better without this tool than with it. I do see how someone who doesn't care could produce a lot of slop, but the people who refuse to use it aren't that guy. That guy has been using it to produce slop for years already. You can use it to produce top quality code if you choose to.

I've got a machine in a corner collecting dust that cost me $12k to build 2 years ago. It runs fine but it's wildly impractical to use as a daily driver (loud/hot). I keep it as a reminder to not do this again. At my current pace it would take me until sometime late 2030 to spend the same amount in gpt5.5 tokens.
You forget that, especially on HN, many people are scaremongering that prices will soon skyrocket. Then it will be another story... I easily run $4k+/mo on my claude sub; if I would have to pay that, I definitely would spend 12k on hardware instead and accept a dumber helper.
Remember that there are other LLM providers, open models, and previous gen models, that are way cheaper that frontier Claude and still way better than what can realistically run locally

> you really need to know what you're asking, and be precise Any chance that you could share some recent prompts to give other HNers a head start on his to approach Qwen? If you are uncomfortable posting them here, my Gmail username is the same as my HN username. Thank you.
I'm glad you're asking. I already started writing a blog post on how to best make use of local models. I'll share it as soon as I have a complete enough list. If anyone else reading this would like to chime in with their tips & tricks, let us know! For the time being, off the top of my head, I'd say: - Prompt Engineering tips & tricks apply here (like being complete in the relevant context you provide in your questio…
I look forward to that blog post!

This is very similar to my setup. Pi in a container (I do let it have network access, just no access to creds or anything, only the one directory that I'm working on at the time and my ~/.pi directory), talking to llama.cpp in another container. I'm on a Strix Halo 128 GiB unified memory laptop. I've never used the frontier models in earnest, I don't believe in using proprietary tools for my programming, so I can't r…

It's ok if you can send your code and data to the provider. Some of us can't.
We're discussing home use. You can. You just don't want to. Huge difference.
You may be, but the topic of discussion is whether anyone is using a local model as their main coding tool.

#489For personal use, yes. I replaced a $100/m subscription to claude in favor of running pi harness pointed at unsloth studio, using both qwen (unsloth/Qwen3.6-35B-A3B-MTP-GGUF) and gemma (unsloth/gemma-4-26B-A4B-it-GGUF) models, depending on my mood. I have a machine I built about 5 years ago with dual RTX3090s in it (I was going to build a new gaming machine anyways, and the llama release had just dropped so I tacked…
> unsloth/Qwen3.6-35B-A3B-MTP-GGUF I've actually tried this exact same model locally as well.. albeit on just a single 3090 at 128k context and I got around 40-60tok/s with Q4_K quantization. The thing that bugged me the most was really the quality of the output on moderately complex real-world coding tasks. Having to switch between "prompt/vibe" and "manually implement" is such a big context switch burden, because y…
I regularly use a pocket calculator: either a physical one, or Apple's Calculator app if I want more decimal places. 'Too stupid' isn't a thing for me if it can cough up some math that would be inconvenient for me to work out by hand. tok/s also isn't a concern because I'm not expecting more than I can read. My ideal scenario would be occasional diversions into querying a 'coding calculator' that can give examples along the lines I want, my way.
I'll make a mental note that Qwen shows signs of being the kind of calculator I'd use for a specific task. Context switching isn't a burden if you're not looking to switch over to vibe/manage and stay there.
