Can someone help me understand - I have tried local AI/LLMs.
Lets set aside speed. The results are ALWAYS terrible compared to CLaude Code.
Sure I only have a 12GB GPU - is that what it is? If I had a 32GB CPU would the experience be as amazing as Claude Code is?
Why is my experience of local LLMs so average?
You can't replicate Opus 5.5 at home.
You can maybe replicate Opus 4.5 to 4.7 if you have some moderately expensive hardware. And that is definitely good enough for many people.
The smallest model that can even pretend to be a decent coding model is Qwen3.8 27B, which you realistically need 32GB of VRAM to run without breaking or limiting it in some really noticeable way. This gets you something like a slightly less capable Opus 4.5 with a much better work ethic.
Strata and Qwen 3.8 flash next is an 180B model running at 70 tps on my 5070 ti and 64gb of DDR4 RAM at Q3 quants and so far I can't tell much difference between it and any other non local model for my workflows/coding needs. Not saying local is better all the time, but it's certainly a lot more capable with minimal hardware than you're giving it credit for. Qwen 4.0 is right around the corner too.
The problem is that "can't tell much difference" is not going to be an objective indicator; you will be very likely to overlook the flaws of the local model and overweigh the flaws of the non-local model. The only reliable way to compare the two is to have your own set of evals based on the types of tasks you regularly perform and then run those evals on Qwen and a frontier model.
The people saying that local models can easily replace the real Frontier Models from Anthropic or OpenAI are just not using it for the same things you and I do.
They seem to be happy with their small usages.
For everything I do, i see huge differences in Quality and Speed.
Even when I try an open model on a 4090, the PC gets warm/hot very fast, I struggle with context length.
This:
Having currently a very tech-intensive chat running for more than one week, this is where the frontier models really shine: Its no more 2024 or so, where they lost context on large discussions, you can do really great work with the frontier models - the local models will be a thing in a few years, if RAM & CPU developed further, this will happen: in 2035 like, you will be able to run "Claude-like experience" on your iPhone.
can you give example, prompt require context window > local model, or higher Quality/Speed, that local model can not do, open source example?
Any program I'm vibing.
I write 5-20 paragraphs of things I want and it goes away and just builds it.
Something like this (just an example):
"Build an application with a webserver in rust. It has 4 stages, first one is an input module... second one is refinement ... third one is an image detection with current fitting ml model ... last one is finetuning."
Then i would describe every basic page with a few more paragraphs.
This would work for half an hour or an hour, consume 100-400k of context tokens and then I would test it, write down 10-50 small sentences (every sentence either fixing a bug, or making it better) which tehn takes again like 20 minutes and i'm nearly done with a complex enough tool providing real value and actually working.
A big kimi, which is hard to run, might be getting close to this but we do not talk about running it on 1-2 5090.
The other thing is, thats more like a practical experience, even if you use them through Open Router (for testing and co), the initial results of something like Opus 5.5 are ALWAYS better. More details, better quality, better understanding of usability of the tool.

Here's a prompt I used recently:
> In a work tree build a feature where each column cog action menu has a "Column statistics" item - clicking that item opens a modal dialog which displays statistics about that column - for text columns that's most common values, stats about value length - for numeric columns it's more interesting than that. Let's do a bit of percentile analysis in there too. Under the hood it works by firing off SQL queries using SQLite window functions and suchlike. For the moment let's have that option only available if SQL queries are allowed against the database, and the SQL queries are built in JavaScript.
You can see a screenshot of what Opus 5.5 built here: https://github.com/simonw/datasette/pull/3038

Oh yes, we're terribly inferior people. Just living on scraps from the masters' tables.
It wasn't meant as a dismissive comment.
I do plenty of experiments of things i always wanted to do and they just don't work with local models.
Finetuning of some ML models for a specific usecase, some 4k demo idea i had, small browser games to show others game mechanic ideas i had for ages, analysis tools etc.
Even just playing around with some Ghidra eats context like nothing.

Have you tried Codex? My journey so far
- 2023 using Cursor
- 2024 using Cursor with Agent mode
- 2025 using Claude Code
- 2026 using Codex with Astra 6
I've try every new model when it comes out from both OpenAI and Anthropic. I cannot justify leaving Codex and Astra 6. The token burn on Anthropic is always astronomical for me. Codex just works, and I see no reason to move away from it.
This matches my experience, Claude limits with Fable blows up the entire 20x usage in like an hour, whereas Astra can run a couple days.
I switched from Codex to Claude Code w/ Opus 5.5, and it's been fine. I haven't hit limits in my $100/mo plan, doing full time dev work all day. But I agree. Codex sub + Astra is also great. Both are excellent options, and I don't see a reason to go with a cheaper / less capable model, frankly.
I think the key to making it make sense is that people have wildly different demands for quality. You will see people say that these small local models have improved quickly and are "good enough for most work". While these models have improved and very fast, it still might be more of a comment on their expectations than the product.
12GB is not a lot, you are stuck on low quantisations of older models with that. What exactly did you try?
The newer/larger models are good though, not as good as Claude, but not every task requires a model of that level. Maybe yours do, but for simple coding tasks, summarising text, etc a small local model runs just fine, and is a lot cheaper than Claude
What graphics cards have more than 12GB, and how much does it cost to buy one? What about for others saying you ideally want 32GB? (That split will determine if a 5080 will do it)
32GB would probably get you qwen3.8-27b at a reasonable quantisation, which benchmarks similar to opus 4.6
You can try that model (and many others) using a cloud host first, and then only if you like it do you need to buy something to run it.
> What graphics cards have more than 12GB, and how much does it cost to buy one?
RTX 5070 Ti and RTX 5080 both have 16 GB.
RTX 5090 has 32 GB.
Good luck finding any of them for reasonable prices, though. I paid $3,000 for my 5090 early last year. I winced when I bought it then. Today, it's like $7,000, and I wouldn't even consider it at that price.
But I'm mostly a gamer that also does local AI as a hobby. If the RTX 5090 was $7,000, I'd still be on my RTX 3080 and still just not started doing local AI and have to turn down the graphics settings in Cyberpunk 2077.

12GB GPU is useless. The good experience is with 128-256GB unified memory architectures like strix halo etc. You don't need to buy any hardware, you can experience the latest open weight MOE (flash) models from DeepSeek, qwen, or GLM on openrouter using a local agent like kilo.
A 3060 + good chunk of system RAM can run qwen3.8 flash next.
That is a shift of comparisons though, right? This thread was about running locally, explicitly as an alternative to cloud services. I would guess few people have graphics cards with > 12GB ram.
A few more will have Macs with 48GB RAM though. (Indeed if you push it a little, 36GB unified is possibly enough for Muse Glimmer; I have not tested this theory)
There is, for sure, a limiting factor in the x86 architecture, but I think the RTX Spark will change that a bit, and maybe AMD's subsequent Ryzen AI/Strix Halo chips.
AMD Ryzen AI/Strix Halo is for running locally on your hardware. Openrouter is for evaluating the models you'll be running locally, before buying the hardware.
In any case, 128-256GB unified memory systems running MOE models is the "cheap" option, RTX6000 is the step above it.

Would you talk to me a mo about Kilo compared to Pi?
I am digging in on Pi (in lovely Paseo and exploring Pendant when in VS Code).
What would I find better or worse in Kilo?
In general, more memory = larger models = more intelligence.
However even if you had a private data center you wouldn't be able to beat Opus 5.5, Astra or Gemini 4. The open weights models are a tier below these three.
Memory manufacturers are running 80-90% margins. Any of a number of things (anti-trust, CXMT, financial shock) have the potential to drop memory cost by 2/3s. At the same time memory efficiency of models is improving. At some point Apple's going to start shipping 64G of unified memory in mainstream machines that are advertised as local AI capable (like HP, Dell and others do today). Like the iPhone refined the concept of a smartphone for the mainstream, they could be the first to hit mainstream sovereign AI.
As amazing? I suppose not.
Good enough? Quite probably, unless you're in the "coding is solved, specify loops and walk away" frame of mind.
32GB (or say a 48GB-unified RAM unified machine) gets you Qwen 3.8 27B at a good adaptive Q4, maybe Q5. Muse Glimmer at Q4 and Q5, etc.
These models can code well enough in an agentic way, I find, and the chat-to-assistant scenario is just fine in Unsloth Desktop or LM Studio.
A slightly lighter harness helps; a lighter system prompt is entirely possible, especially for Muse Glimmer, which is post-trained so effectively for agentic helper tasks that it barely seems to need a system prompt at all except for a "plan" mode.
Tool use is all fine, all that.
> unless you're in the "coding is solved, specify loops and walk away" frame of mind
which is where the entire software industry is going
Well it's certainly the service-dependent (addicted!) model that the big two want.
But will you want to do that when your tokens are metered at non-subsidised prices, and yet there is absolutely no clarity (ever!) about token efficiency, how the model decides to spend your money, how it might ever decide to stop wasting your money and get to the point, etc.?
The specify-loops-and-walk-away model absolutely points to local/on-premises/private cloud AI.
Because otherwise you're letting Anthropic or OpenAI decide how to spend your money. And they are going to be biased towards spending more of it.
I don't think Qwen 3.8 is quite there yet with the loops stuff. Definitely seems to be better at deeper and deeper one-shot puzzles.
uhhh mission critical software is nowhere near turning over full control to _any_ LLM...
12GB GPU is insufficient for most purposes yes. Even 16GB is a notable improvement, but yes 32GB cards such as the 5090 or R9700 are a world of difference.
Given we're discussing a cost comparison (i.e. cutting a Claude subscription in lieu of running locally), how many months of claude $100 or $20/month plans would it cost to buy a 5090? I am showing it as 88 and 440 respectively. I.e. a 7 and 36 year payoff. Not even close to being worth it.
You also get to keep your data private (so you should compare it to api pricing), there are no forbidden topics (i just did a pentest on my webapp), and multiple people can use it. Basalt does 150 tok/s on a 5080
Currently, it's not worth it because:
"SemiAnalysis, a research and analysis company specializing in the semiconductor and AI industries, found that a $200/month subscription plan is far more generous than previously thought. According to its calculations, while it's widely believed that a $200/month plan maxes out at roughly $2,000/month in tokens (assuming API pricing), the actual numbers are closer to $14,000 for ChatGPT and $8,000 for Claude. "
https://cybernews.com/ai-news/chatgpt-claude-usage-costs-ope...
This will change in the future.
The Claude plans are probably still heavily subsidized. Expect prices to increase, especially after the IPO. Self-hosting models for personal use is probably overkill, but I can see companies doing it pretty soon since they can probably run 24/7 workloads and fully utilize the hardware.

Reminds me of linux gaming 10 years ago. According the to the community everything worked great without issue and any issues were hand waved away as tiny bumps that you won't even notice.
Then you would go try it and be back using windows to game a week later.
But that is not exactly a linux issue. Games built for linux works very well on linux like games built for windows running decently well on windows. Linux can also run some games built for windows - not for linux. And that are the ones that doesn't provide first rate experience. Those windows games executables technically should not even load as it is not built for linux.
Everything considered, linux is good and has decent capabilities including gaming and whatever you can throw at it but only do oranges to oranges comparison. Games and apps built for each os works fine on the respective os, well atleast it is true for mac and linux. Windows is very unreliable.
Imo, this is just the tech version of virtue signaling. Everyone knows local models are objectively just worse than frontier/cloud closed source models for most commodity hardware setups, yet people insist on using it because they want to be contrarian or "stick it to the man."
Your experience is average because it _is_ supposed to be average. The people using local models tradeoff taking the moral/technological high ground vs actually using something high quality to get a job done quickly and with high quality, and largely autonomously. They are ok with subpar output because they will handhold the model more, or the (subpar relative to the frontier) outputs are sufficient for their toy use case while being cheap and accessible, with the added benefit of being able to run it on their private data without sending it to a 3rd party.
Almost no one at any job where software is the main economic output is using a local model to code. If you actually require intelligence to get a hard job done, you should just use a frontier model.
> If you actually require intelligence to get a hard job done, you should just use a frontier model.
Or, you know, your own intelligence.
What I do not understand as an engineer is how our community has gone from believing in open source for controlling destiny, security, etc., from avoiding unnecessary corporate capture (think of all the rants about Swift!), from believing in heterogeneity and portability, to just saying, look, if you're not using the product of one of two loss-making AI unicorns to do all of your work, you're just being a contrarian weirdo who is doing it for performative reasons.
I guess if that is your definition of contrarian — that everyone else is doing it so why aren't we? — then I am.
But in my experience it's not so different to "why aren't you on social media?" — which was an argument from insecurity and the desperate need to fit in.
I personally believe in independent thinking. I have things I want to learn about how all this actually works, I have questions about my own life and future, and I'm not going to simply chuck them away because you or anyone else thinks it's just being contrarian and we shouldn't question the direction everyone is taking. So I am learning the tech with a stack I control, while continuing to do the job I do.
You can do what you want. You're probably right, and I'll be quite happily wrong and continue in my wrongness even though, based on how you characterise it, this kind of independent thinking appears to unsettle you.
Because local models are significantly worse? I'm not so sure what your question is. What else did you expect? If you could just build Claude Code at home, Anthropic would be valued at closer to $1.1M than to $1.1T.

I can't really do anything with this comment without a couple of specifics, such as 'what model are you using?'.
So for a sense of scale, un-quantized 1 parameter == 1 byte of ram. 12Gb means you could have roughly 12b parameters, frontier models like Kimi k3 has 3 trillion parameters, so you'd need ~3tb of vram.
32 would get you a good Qwen 3.8 27b which is like Opus 4.6.
12 GB isn't a lot. You need a lot of VRAM or RAM for context window.
> The results are ALWAYS terrible compared to CLaude Code.
How much effort did you spend to make the local setup work well?
Local models are not plug and play, you need to adjust settings to make them behave intelligently.
On my side one model looking super dumb right after install ended up being 'agentic' after using the right chat template, fixing how tool calls are setup, fine-tuning plenty of params values, and adjusting the whole setup to my own hardware. Claude.ai (free) was great at helping me sort that all out.
I really strongly agree with this statement. A bunch of people aren't even engineers, and their abilities aren't that good either, yet they keep saying that open-source models can replace OpenAI or Anthropic's models.
If that were really the case, basically nobody would spend so much money using them.
With my DGX Spark + 5080 + 3060 setup, I've tried all kinds of approaches, including quantization, acceleration, fine-tuning, post-training, and everything else.
It still can't compare to Opus 5.5 max in terms of speed, capability, and stability.
And when I calculate all the money I've invested, directly subscribing to the service would actually be cheaper, more efficient, and more stable.
Open source is great, but don't glorify it.
The architecture of the code I develop has never been simple. If you're someone who doesn't even work on things that need to be deployed to something like k8s, then basically, open-source models are indeed enough for you.
>Sure I only have a 12GB GPU
Found your issue.
