You have dense models (qwen 27b, gemma 31b) who are pretty smart, but pretty slow
You have MoE models (gemma 26b, qwen 35b, north mini code 30b) who are pretty fast, but make a lot of mistakes
You need a lot of memory to run these well, quantization makes tool calling weaker, so most run at 4 bit quants and are wondering why it kinda sucks and that's because you've essentially lobotomized the model (I recommend unsloth quants, i recommend 6bit for MoEs and 5bit for dense)
So you need a lot of compute to make the pre-fill fast, you need bandwidth to make the decode fast, you need a lot of memory to hold everything - lot of ifs
On top of that, your laptop becomes a loud hot churning machine, it's uncomfortable to work with.
So are they good? not really. Do they work? yes
The best "free" experience I've found is using OpenCode with Big Pickle. It's not especially smart, so it often won't produce the correct result the first time, but the free tier is generous enough that I don't think I've hit the limit more than twice over around a month with frequent multi-hour sessions. If running locally is truly the goal, it's not going to fit the bill, but if the goal is just "get the best experience without having to pay for a sub or tokens", it's the least bad option I've found so far.
This setup is extremely optimized down to the last flag. Changing any param from temp and below craters performance.
The Q4_K_XL bit for those not in the know.
If you throw the right GPUs at the problem, they become much better - but still not quite in the realm of Sonnet or DeepSeek 4 Flash, let alone Opus / DeepSeek Pro or Mythos/Fable/GPT-5.5.
Given enough budget, power, and cooling, you can run some pretty good data pipelines, but for code, I think it still makes sense to shell out to an API provider most of the time.
Ultimately if you skip over the opportunity to play with these models on your own machine you are losing out on a lot of really interesting educational opportunities — it helps make a lot of stuff feel more concrete in a way that only tinkering can.
But then I think once I had an idea of something that I was building against Gemma 4 or Qwen 3.6 I would be looking at openrouter etc., to stabilise it for the next tier of experimentation (and to get back a kind of multi-device access without tailscale/lm link etc.).
Are they good enough to replace what people seem to want to do with Claude? Maybe not. But it's an unparalleled learning opportunity.
It outperforms all the Qwen models (even 100B+) for rule following/automation style tasks in my experience. Its image interpretation is also very good, and out-benchmarks Opus.
Qwen seems to ignore instructions and consistently outputs incorrect formats (when token generation format is not explicitly constrained)
But yes, on the DGX Spark Gemma 31B Q4 with MTP runs around 20 tok/s and Gemma 26B A4B around 60 tok/s. Still quite slow. But on a high end Nvidia card would run significantly faster and still fit in memory.
I'd recommend for anyone getting into local models to focus on memory bandwidth over RAM. Models under 100B parameters are now sufficient and hugely useful for automation.
I agree that for coding/creation use cases, there's still not a compelling argument for local models.
But e.g. if you want to scan a list of stocks and interpret news/high pass filtering, interpreting logs, interpreting screenshots, the local models are more than sufficient already.
Gemma will just stop mid-tool call. It's been slower and I've had to reduce context size to run it. Qwen3.6 27b has been rock solid using club 3090's single card setup for agentic use -- https://github.com/noonghunna/club-3090/blob/master/docs/SIN...
E.g. prompt A to achieve X, output in format Y. Use Y to do something in prompt B.
Agentic loops will underperform deterministic control flow pipelines (with non-determinism constrained to LLM calls).
Agents are more general, which is the main advantage. But inherently a more general solution will waste context on unnecessary reasoning.
Try asking Qwen to output a JSON in a specific format. It basically can't do it consistently with a moderately sized prompt unless you constrain the token generation via GGML or are extremely repetitive and specific about it. (Thinking disabled)
Gemma 4 will do it correctly pretty much 100% of the time. (Thinking disabled)
Applies to other rule following as well in my experience
I'm really surprised how much slower a DGX spark is for the same price.
1. Here's my command.
PYTORCH_CUDA_ALLOC_CONF=expandable_segments:True \ vllm serve cyankiwi/gemma-4-26B-A4B-it-AWQ-4bit \ --dtype auto \ --gpu-memory-utilization 0.95 \ --kv-cache-dtype fp8 \ --enable-chunked-prefill \ --enable-prefix-caching \ --trust-remote-code \ --enable-auto-tool-choice \ --tool-call-parser gemma4 \ --reasoning-parser gemma4 \ --max-num-batched 16000 \ --max-model-len 64000 \ --max-num-seqs 12 --speculative-config '{"model": "./gemma-4-26B-A4B-it-assistant", "num_speculative_tokens": 4}'
You can run multiple instances of these models in parallel on the DGX Spark which somewhat mitigates the difference if your task is parallelizable.
But I'd take the simplicity of a single thread and higher throughput personally.
Overall of course still better to wait for next gen devices if you can.
If you don’t need the machine to respond instantly (or explain your own business model to you) everything can be local and it’s been like that for a few years now.
I don't care how many tokens per second of nonsense it can generate.
It is probably not smart enough for "design this whole architecture of this complex system from scratch, make no mistakes", but that is not something I want from a coding tool anyway. I want a model that I can point to a file and tell it to make some changes to the file and related files. Or that I can ask to review a PR with regards to certain aspects.
My suggestion is to simply try it and see what it feels like.
you get a macbook for work, you run the macbook
they're not going to start giving GPUs to employees to run local models
You generally want to run q8 or some kind of "6bit" quantization at least.
40GB of VRAM is the entry-point in my experience, you can run qwen 3.6 35b a3b with full context or qwen 27b with about 92k of context.
Before you get fully discouraged, you don't need 1 gpu with 40GBs you can use multiple cards, with minimum impact on performance.
i use it usecases like that latter and they are fine.
It is such a downgrade. I don't understand how that's even possible. The thing has so many strongly-held opinions I did not ever ask it for, talking just way too much and generally feeling somehow dumber.
Of course, being significantly larger, it will encode more knowledge, but that doesn't help me when I hate talking to it. And all that on top of the fact that talking with it costs real money.
I wonder what it might be that makes me hate it so much. Maybe because it doesn't see itself as a tool but almost an equal? As if its opinions would have weight.
Qwen too can act like an overeager intern, but if you tell it that it is an idiot, it will drop that ego. Not so much with Claude. In my experience, anyway.
Anyway, point is: full ack on that headline.

Gerganov, hope you will consider developing further the CLI cause we suffering with the server.
Curious if you can share the prefill speed too?
I run locally on a crappy desktop (some AMD iGPU with Vulkan llama.cpp, 32 GB DDR4 RAM) for experimentation. I get 15 tok/s on generation for the qwen & gemma4 MoE models. I get around 150 tok/s prefill speed.
Reason I'm asking about the prefill is looking at my stats at work, I use between 20M to peaks of 300M input tokens daily. Some of those token are cached but in general, I seem to have roughly 500x more input tokens than output. So interested in prefill tok/s stats.
Huge Thank you for llama.cpp btw!!
Also, I get a lot of mileage from the ngram-based speculative decoding functionality [0] as it allows me to iterate on the implementation much faster.

Plus, I never have to worry about rate limits, quotas, or sitting in a queue during peak time. And I can always see its full thoughts, don't have to worry about where my data is getting sent, and know it can't get secretly nerfed.
Running on 2x 3090, 500-1000tok/s prefill and 60tok/s output at Q6_K_XL with MTP on llama.cpp, 220k tokens context window (starts to get a bit dumb above 160k ish), no KV quantization
For this reason I wonder if local models are a potential business opportunity. Provide the service to engineering teams to give them a pre-built and setup GPU rig they can run in a closet. No need to worry about all the things you mentioned and clients can rest-assured their data isn't disappearing into a sketchy data center. There might be regulatory reasons that make on-prem setups appealing as well.
[edited for format]
If open models can ever hold roughly 600k token windows, I'll be really excited, I found that around 300 ~ 400k of Claude reading through your codebase results in better outputs. I also have Claude read official docs instead of "guessing" as to how to do something.
I think deepseek v4 pro has 1m context and does pretty well up to around 600k. But if you have the hardware to run that locally, you already know
Even then if there's a smaller model with 1M context, you'll need a ton of RAM to actually run it at full 1M. I guess that's why you don't see it too much. Anyone that could run Qwen 3.6 27B with 1m context would be better off running a much bigger model with smaller context instead, in the same amount of VRAM.
In terms of optimizing further, huge context + KV quantization sounds like a terrible idea, but there's some decent innovation in sparse attention, KV cache rotation allowing Q8 to perform nearly as well as full 16-bit precision, plus some ideas around offloading KV cache to system RAM (but I'm skeptical)
I think the way these models work excludes sane behaviors the larger the context gets as each token introduces potential ambiguities between "USER" and "SYSTEM" messages leading to all the catastrophic behaviors.
Anyway, with AMD395+ I'm finding ~100k is both speed and context usefulness unless it's scoped tightly. with opencode, I manage it with dynamic context pruning: https://github.com/Opencode-DCP/opencode-dynamic-context-pru... ; then anything I touch ends up being refactored so context doesn't get bloated with unecessary functions, etc.
Obviously, this isn't compatible with certain business codebases, so I can see why bloat meets bloat.
OMG this is such an annoying property, just shut the hell up please, and be concise.
I suspect that this is an artifact of the thinking property, but please just summarize the thinking process far more concisely, where a single sentence answer is more than sufficient the frontier models seem devoted to going on to a minimum of 5 paragraphs and offering 3-5 new directions.
And requests to please only offer a single step at once, or single option at once, or to even stop eagerly offering future directions is really hard to prompt correctly.
And look, there I did exactly what I was complaining about...
For example, the Claude web UI has an Instructions field where I have told it never to congratulate or praise me for asking questions. Earlier Copilot models used a ridiculous number of emoji and bullet lists when answering literally every prompt, I told it to knock that off and prefer detailed paragraphs in prose.
Local agents/frameworks/whatever all have their equivalents for overall user preferences.
Asking Claude for this provides incorrect instructions for me, so I'm guessing it moves around a lot.
Edit: also, how can I stop the LLM from all this fake glazing, as if every question I have is some sort of unique genius insight, it's so damn annoying. I just got the third straight round of this while merely trying to get summarization of a PDF:
> Good question — it gets right at a real tension in the paper. Let me check the current state of actual SV-imputation efforts, since this has moved since 2020.
This is likely due to a combination of mass funding for the AI companies, but also they are trying to governmentally restrict which countries get access to these cards so certain countries get a head start. The only way to lock that down is to have them literally locked in their own GPU prisons (data centers). Third reason is it does make it possible to train the models faster by having them in the same data center connected directly. Having them distributed to everyone would slow down training considerably.
The current way to 'own' decent RAM and GPUs right now is through the stock market it seems.
Hmm. I think I might just fundamentally disagree with Anthropic about the idea of what a "tool" should be.
I’d think the volume for that category would be low but LLMs aren’t just for coding.

My Mac only has 16GB of VRAM (20GB total - 8 is reserved for the OS) so I have to leave room for VRAM, I usually find a model that fits in 5 to 7 GB of VRAM and then max the context window as much as I can.
Works perfectly fine in llama.cpp throwing 70+t/s at me with 128k q8 K/V context when using the IQ4_NL quant + MTP at q4 MTP K/V.
Also leaving this here because you might find it useful: https://hypfer.github.io/will-it-fit-llama-cpp/
It won't happen with AI models either.
It's almost ingrained in the American business model now. Outsource everything. Nobody wants to manage a room full of servers when they can spend 2-3x as much and outsource that headache along with the responsibility for it.
Same will happen with AI. Whether that means paying Anthropic that premium or paying AWS.
I'm in a relatively small business, we recently had an outage related to our local infrastructure.
I got pressure from the CEO saying it wasn't reliable to host our own infrastructure anymore even though our total internal down time over the last 5 years is significantly less than even a single of the larger recent AWS outages.
Everyone wants to shuck the chore and the responsibility.
AI is different.
Cloud computing genuinely is cheaper on average. It's better than paying for cisco servers, and at scale, it's cheaper than managed platforms (ala Heroku), and it's a coin toss for when you're in the middle ground and constantly approaching the point of rebuilding poor-man versions of existing products but with very very expensive engineering salaries.
In contrast, local models offer dramatic savings, and are magnitude of orders better in certain aspects: like stability - the performance is all over the place with traditional AI companies as they divert compute to their next big thing.
The benefits to maintaining your own infrastructure are pretty moderate to low, with very high risk.
And also, alternate models are pretty easy to use and easy to swap out unlike the vendor lock-in that exists with cloud services.
Same reason people pay for things through the AWS marketplace (like Vanta) instead of having to go through their invoicing process.
But AI is just weights, you can run a reasonably intelligent model at home, or on a few GPUs if you're a small-medium sized company, and it doesn't require dedicated maintenance.
Same here. My job as a software dev does not require me to self-host services we need and use. Quite the opposite. But, I am reluctant to hand over all control to AWS or equivalent for several reasons that I will get into here.
I have found that Infrastructure as Code (IaC) and modern tools like opentofu, ansible, combined with frontier AI models and harnesses gives you superpowers in this space. Almost all of our self-hosted services are fully managed by these tools. e.g. We perform backups and test them more often now than we ever did before. Entirely because it is so much easier to do all of that now.
The OS needs updates, file systems get corrupted.
Fans get dirty.
All the things that you need to deal with in hosting your own server infrastructure you have to deal with when hosting your own AI infrastructure (which runs on servers...)
You know what gives me headaches? When I'm in the middle of a session and the model gets rug-pulled out from under me because somebody at the model provider didn't pay the Trump bill that month.
Or when someone at the model provider decides that the curve-fitting algorithm in my graphics package looks a little too much like Skynet for comfort.
Or when they do any number of other things to undermine my work for the sake of their business model, some of which I won't even notice until the damage is done.
The sad thing is, if you know how inference works, you know that it really is insanely wasteful for everybody to run it locally. If anything naturally belongs in the cloud, it's inference. But at the same time, what choice are we being given?
I think that's basically Geohot's business model at Tiny Corp.
What's interesting/exciting is that local models are _already_ quite good at tasks we never imagined AI _ever_ doing before ChatGPT hit the scene just a few short years ago.
We're also in an interesting point in time where companies are releasing the fruits of their research/labor (the LLMs) to the general public for free. For now, I think they see it in their best interest to gain mindshare and rapport, as well as advancing the state of the art in smaller LLMs ("a rising tide lifts all boats") but I fear and expect that these will dry up as the major players buy the minor players, and all will seek a return on their considerable investments in AI research.
If things change to token usage billing for everyone, maybe I'll be singing a different tune but on a subscription, I don't think it makes sense financially.
Fun? Yes. Financially sound? No.
Accountants are reasonably good at figuring this out - there are a lot of different things that need a large upfront investment before you can charge anything. People still debate if they are correct in this each case.

But, for smaller more well-defined workflows, or as straight "edit this part to be like this exact" edits, they seem more than enough. Still waiting for them to become mature enough to be able to replace what we have as SOTA today, I'd say it's ready to be switched over then.
Speaking of local models, DiffusionGemma (and diffusion models in general) should not be slept on for local usage! Usually the problem locally is that the LLMs aren't efficiently making use of your hardware, unless you start batching requests and run many at the same time, but that require different approaches in general. Instead, diffusion models work much faster for individual prompts, and not by a small margin either.
Today I finally finished porting diffusiongemma-26B-A4B-it support from Transformers into Candle, and together with some optimizations I now have it basically flying with ~450 tok/s (~19 it/s) in Candle during inference, instead of ~180 tok/s (~11 it/s) from HF's Transformers library. Even using vLLM with similar sized LLMs, I don't think I've ever gotten past the ~250 tok/s threshold for single prompts, exciting stuff for local models :)
Diffusion models can't really be trained beyond low-to-mid size and have lower quality than an equally sized, plain one-token-at-a-time model.
The 27B is the smarter, more reliable one - but it is slower. The 35B is faster, still very smart but below 27B, a bit less reliable. The reason is the MoE - Mixture of Experts architecture, which only activates a subset of parameters, making the model much much faster.
I run the 27B on a MacBook Pro M5 Max + 40 GPU cores + 128GB RAM (well, on this beast I can have 27B + 35B in memory at the same time with headroom for all the other stuff). But because this is a laptop, it is not possible to run local LLMs all the time - it just gets too hot and too loud.
What excites me more: I run the 35B model on a MacMini M4 with 64GB RAM. It is fast, it gets a lot of work done (e.g. it scans, extracts and classifies my emails, it watches the mailbox all the time and does work). I also use it as my private Hermes assistant ("when is the next Starship launch?", "who is playing today at the World Cup? Give me some trivia").
Next step I am planning is a RTX Pro 6000 Blackwell workstation I can put in my basement. I want to run qwen really fast, with multiple threads / prompts / agents at once. And MAYBE if the budget allows, a 2x RTX Pro 6000 setup in order to run DeepSeek v4 flash on it (to run research on it).
Also, it will just be faster - and more fun too.
Edit: Obviously you'll be using more tokens but this is the trade off for running a smaller model and running locally. Similar to time memory trade off but in token economics. Sorry I need more coffee
If you're resourceful, you can even run SOTA models. KimiK2.7, MiMo-V2.5/V2.5-Pro, MiniMax2.5/2.7/3, DeepSeekV3.1/v3.2/V4-Flash/V4Pro, GLM5.1, Step3.7-Flash, Qwen3.5-397B, Qwen3.5-122B, gpt-oss-120B
The cloud-based models are fine for big and complex tasks, but the pricing is ridiculous for small stuff—like summarizing a discussion or fixing a small bug. And cloud and privacy have never been a good match.
As an example, this comment itself was written with the help of Qwen3.5-4B running locally with an extension on top of llama.cpp default web UI [1]. The extension injects my browser's context directly into the conversation, which allows me to summarize things and draft up comments quickly. Speed is pretty acceptable for the size: ~5s TTFT and ~100 t/s generation, all running on a Macbook M5.
And when I want to run bigger tasks, I don't just stick to one provider. Apart from well-known closed-weight providers like OpenAI or Anthropic, I also experiment with open-weight models like GLM-5.1, DeepSeek V4, and Qwen3.6-27B, which provide quite good results for the price.
I'd argue both have value, and I don't see why anyone needs to choose one exclusively. Anyone else doing this?
[1]: https://github.com/ngxson/llama-companion
Also, a lot of my day-to-day tasks perform the same on both small and bigger models: summarize a web page, draft a response, translations, quick web search, etc.
I'm assuming privacy is not a concern since you mentioned using Deepseek already. The cost of V4 Flash for small tasks is so minuscule as to be almost free, and you don't have to deal with a churning laptop (or even buying a high-end laptop, for someone who doesn't already have one).
I guess what I'm really asking is, what's the advantage of using these small local models if privacy isn't a concern?
However, like many commenters, I don't really believe in vibe-coding, long-horizon agentic one-shot agentic coding, etc. and do not use LLMs for huge generation tasks that involve designing things end-to-end.
I also have an MBP with 128 GB of unified memory and do quite a bit of Qwen3.6-35B-A3B. No, it's not as smart as the aforementioned models, to say nothing of frontier, but many people seem pleasantly shocked by the number of banal tasks that do not require these.
LOL - some of us have a budget
If you're a professional that's confident in a positive return on the investment (optimal or not), or just a hobbyist with the luxury budget for a "shop" that cost is well within norms.
That's not everybody, of course, but it's not some inconceivable fantasy. A lot of people in the tech community here on HN, specifically, end up with pretty high discretionary budgets that they pour into stuff like this.
Still cheaper than a new Mac. Maybe not cheaper than a used one.
Top 10% of global earners (~800M people) can afford a $2,000 device without major financial strain.
Top 25% (~2B people) could afford it with some budget adjustments.
Bottom 50% (~4B people) would find it prohibitively expensive.
So for a SV top income, maybe that might look more like the weekly pet brushing budget, but for most people out there this is not that much of a no-brainer.
Besides those with effectively unlimited budgets for their personal compute, local models are still a long ways off.
Though, that shouldn't be conflated with the value of open-source models, which can be used by cloud providers to significantly reduce cost of intelligence.
There are segments, everything from "Average person in world" to "Average creative professional using computers for work" and more on HN, with a wide range of costs for the hardware. HN probably skews towards the latter rather than the former, probably sitting with enterprise hardware next to them basically for fun, hard to make wider conclusions from what people here have or not.
It's just for gaming and AI now. Maybe not even gaming as much anymore.
Consider the perspective of someone who has a practically unlimited budget for PCs, doesn't game much anymore, and doesn't need AI to do their job. It's just part of getting older, and there are plenty of people in their late 30s and older on here.
I'd assume a Mac with 32-64GB memory would get some reasonable results.
You can be far more ambiguous with your tasks with the larger proprietary models as opposed to the local models. You can achieve the similar results with local models but you need to be much more detailed in your prompt.
One of the biggest things about running these local models is that the harness matters almost just as much as the model too. Codex is optimized for GPT models, CC is optimized for Claude, Cursor has a great harness that works very well across these providers. It took me a couple of iterations of the different harnesses to find one that would work well with the smaller Qwen models to do local coding.
I don't vibe-code, but I do decide what to implement and what patterns to use (perhaps asking the model to analyze and give advice on this first), then I have it handle the nitty-gritty of the implementation itself. For this usage style, the latest local models are as good as having Claude at home.
I won't say it's been _easy_ (I ended up implementing my own harness to accommodate the idiosyncrasies of local models), but I will say that for the effort, having a coding agent that's essentially free to query as much as I want has been life-changing as a dev, especially when it comes to working on side projects. Knowing that my agent will never get worse in quality, suddenly cost more than it does now, or be suddenly made unavailable by external factors, was absolutely worth the trouble. And on top of all that, I can't believe it's as good as it is.
The good news might be: opensource models are now good (enough) for day2day usage. But is it really? I feel that companies will always naturally strive for the best and use the SOTA (as long it is not too expensive).
I see OSS models being a good backbone for companies in the future that have validated workflows and could use those for privacy or to spare costs.
IDK, might have gone a little bit off-topic here.
Currently maxing out two Claude code accounts every x hours when working on large code migrations or setting up new iOS apps etc - most of time it’s fine but occasionally it’s mega frustrating!
With 96GB I'd start with the Gemma 4 and Qwen 3.6 models. Any of those should work fine.
But for coding in a harness? In my experience it's unusable even for small projects. It just gets hard stuck at every little problem, wasting hundreds of thousands of tokens trying to make a convoluted solution work instead of doing the obvious thing. Or it will spend hours trying to reason through a fairly simple code flow, incrementally adding debug print statements, only to get confused by the output and then editing completely unrelated code that it convinced itself is the problem.
I've tried instead giving Sonnet the problem description and code and have it come up with a detailed plan that Qwen should implement, but doing that actually consumes a significant amount of tokens compared to just telling it to implement everything, and the results are honestly not that much better. There are just too often subtle issues with the plan that Qwen doesn't recognize when implementing, but make the resulting solution it comes up with unusable.
These models are very capable, and use around 20-30GB of RAM while they are running.
Provided you have 64GB of RAM that leaves space for running other applications at the same time.
I used to assume that anything GPT-4 equivalent or higher would need $30,000+ of server-class hardware.
That said... gemma-4-12b-qat is 7.15GB on disk so should run reasonably well in 16GB, that takes it down to MacBook Air territory https://lmstudio.ai/models/google/gemma-4-12b-qat
To be fair, I think the labs are also interested in this (e.g OpenAI parameter golf). But the incentives are tricky. When the subsidies and tokenmaxxing era ends, local models will be essential.
I’d love it if model providers just let old models run and let us pay less, but the deprecation makes me want to look into local models.
I have been considering getting the 58gb Mac Mini but that is a decent amount of money to spend without confirmation on a) how fast is it and b) will it work for well-defined tasks.
The good old butt dyno!
I’ve been eyeing local models more and more with Anthropic squeezing more and more on the subscriptions. A few comments on HN had me waiting until they improved more but this article makes me wonder if I should reconsider that.
I’ve been doing some pretty niche development using a game and a script extender for said game. If these models can handle that, I’d feel good about switching.
I closed the article after that.
The author has no idea what a privilege it is to have a machine like that for personal use, and how 99% of the population are not going to afford a setup like that.
Just some back-of-the-envelope maths will tell you that a $20/month Claude subscription makes much more sense financially.
What % of developers could afford an older MacBook model, second hand? Far, far more than 1%.
Running locally is the bar; it's hard to make these things a service which scales.
Make some tests, and its 8 bit version runs at 30tok/s when using llama.cpp with MTP and run on Macbook Max M5. I have 128 GB, but but 64 GB is well enough. https://github.com/stared/benching-local-llms-on-apple-silic...
When using benchmarks, it gives more-or-less the level of SotA mid-late 2025.
The other thing that people tend to gloss over is that you really do need to spend some $$$ on decent hardware. Yeah, you CAN run some 4-bit quant with heavily quantized cache on your 16GB card, but it's not going to be a great experience (I think this is where a lot of the "if you think it's gonna be any good, you're going to be disappointed" stuff comes from). Yes it's a lot of $$$ upfront but it's very much unknown when hardware prices are going to come back to reality. There's a lot of hopes and dreams that any minute now an H100 will be worth pennies because "that's how it's always been" w.r.t. computer hardware, but we are living in interesting times. So you can't just make the tired old assumptions that a Claude subscription over three years time will work out to be dramatically less than the value of some card three years from now. We STILL have basically anything with >=24GB VRAM appreciating in value, which is absolutely wild. What I'm saying is, the depreciation curve may very well be a lot less dramatic and fast than it used to be, going forward.
So i've tested a couple, and the speed is finally impressive. My colleague uses paid tiers of claude and GPT, and the speed is comparable. Maybe even slightly faster on my end.
The problem is: i'm running the model on my work laptop, a 12th gen i5 with 16GB of RAM (which, you know, i asked to upgrade to 64, but that was right at the time of the great RAM shortage of the '20s) so i'm pretty limited in what i can use. And this is running alongside the usual suspects: Web browser hugging 1.5GB, MPLABX hugging 3, windows taking at least 5 just to sit idle, thermal throttled to 1GHz ... And yet its speed is comparable to a paid service. A lunch's worth of tokens vs a few cents of power.
So, what i found, what i fount... What i found is that i need AT LEAST 16k of context window, otherwise they will halt when i pass a small C file for analysis. And coding models will shit the bed with 4k. But we all know that, context size is King.
I found out that Qwen will keep looping while thinking, but that's not a surprise to you, either. But give it enough time and you will get an useful answer. I was hoping to using it as a better warning system for some languages, but i fear i need muuuch more context size, because i tried to feed a file that had a function with an endless loop:
At 4k context it almost shit the bed if i gave it just the offending function, then told it where to look at. At 16k context, with the whole file, it needed some guidance to what the problem was, and after 10-15 minutes of thinking it found the issue. Problem is, it kept second guessing itself for another 20 minutes on the same unrelated thing before giving the output. For which the fix was wrong, but the semanthic was correct. Good enough. Maybe it will be faster if i don't ask for a fix (which i didn't i just asked to look for a specific issue)
Wish i had 3 times the RAM so i can see what happens with more context.
Then i gave it the task to analyze a C file to make an API document. It took half an hour, but then i had a good starting point, which i had to keep changing because it would confuse commands with IDs and things like that.
This was the Qwen 3.5 9B model.
I then tested Gemma 4, being impressed at the tokens per second it gives on my Pixel 8A. Same tasks: same issues with short context, with long context it gave absolutely useless answers when looking at code, but it took 1/3 the time of qwen.
In producing documentation, instead, it was much faster, and it never hallucinated data. Good. in 15 minutes i had everything done.
Not bad for stuff running on a business laptop, while doing actual work.
Tomorrow i will try Qwen 3.6, let's see how it goes..
