I’m curious to know if these local AI setups are legitimately useful compared to cloud. I’ve struggled a lot to get something useful out of the hardware I have.
I realize I’m somewhat limited (16GB RX 9070), but still, it seems really far off from the kind of experience even a basic $20/month subscription gets me.
Any tips anyone might have are appreciated! I’d love to be local first and would be willing to buy hardware to get there.

The $20/month subs are much stronger than the local models you can run, even with how far local models have advanced lately.
The appeal of local models is that the data never leaves your network so you can feel safer putting sensitive content into it. It also feels “free” to use when you’ve already paid for the hardware.
But it doesn’t perform better and if you do the math you’re probably not saving money either. It’s helpful for things that you can’t or don’t want to outsource to a 3rd party.

Uncensored models are also popular reasons, although it’s more of a niche.

i'd say 'with' instead of 'from', the cloud provider rents you the hardware, what you run on it, is whatever you show up with

It also takes some load off the AI data centers.
IDK if that might be a concern for Apple or their AI partners.

It worsens the supply crunch, no? A unit you use sparingly vs that memory going into a GPU that serves many more people.

Surely this is not something that motivates the vast majority of people using local LLMs.

I just ordered a new Mac Studio M5 Max 128GB $5899 ($6400 with tax) to be able to run the bigger "consumer size" models in the 70B parameter range (~96 GB). That said, I have no illusions that this expensive setup with a Qwen Flash coding LLM will be comparable to a $20/month subscription. Even upgrading to an even more expensive Mac Ultra 256GB for $10000 to hold a bigger model still won't be comparable. Apple hasn't shipped my Mac yet and I'm still considering cancelling it and downgrading to a smaller 64GB RAM config ($4299) to save $1600.
Why did I initially spend the extra $1600 if I knew ahead of time that it wasn't as good as cloud AI? Because I thought I could use some local LLM for the easy tasks or when I hit cloud rate limits. No issues with privacy so that wasn't part of the motivation at all. I just wanted some local AI capability to augment a subscription. I've not totally convinced myself of the cost/benefit of this.
Based on today's consumer hardware landscape, you're paying very high prices for crippled capability compared to the cloud AI subscriptions. We're also in a transition period where the next iteration of hardware improvements have some compelling features for local AI. Apple's upcoming M7 (2027 or 2028) is anticipated to have better GPU and neural engine to help with prefill TTFT. AMD Strix Halo is about to release 192GB system which is a big upgrade to their current 128GB ai pc. Maybe apply my $1600 savings towards those newer products. Those future products will still be very expensive but maybe the cost/benefit will be better.

In my experience so far, separately from privacy concerns there's a specific use case where cheap local shines--when unlimited shots on /goal with a dumber model is better than limited time with a smarter model. This looks less like the assisted-coding scenario that's commonly brought up as a good local scenario, because if you're searching for a fast and accurate solution to a single blocking problem, the bare minimum for a model that can do that is a 24GB dGPU or a 64GB Mac. Instead, this looks more like a Hermes agent on an Raspberry Pi driving OpenCode on an old gaming computer with just enough RAM and VRAM to handle an MoE, churning out something overnight that would quickly exhaust the subscription plans, like a knowledge graph for a large document corpus.

I’ve been running DeepSeek 4 Flash, Qwen 27B and Qwen 9B on local hardware. They work well for coding and document review tasks. I think Qwen 9B local on a 5090 might be legitimately helpful for small task agents in omp, since it is ridiculously fast. But my motivation is that I have data that I unfortunately can’t share with 3rd parties.
I have been eyeing a 512 GB Mac 5 Ultra to run full DS4 pro locally, which I expect would be pretty amazing as far as quality/recall. The only downside is that the speed is a lot slower than something like 27B on the 5090.

16GB VRAM could load a small quantised qwen 27B model but it would be a ways away from a frontier cloud model.
Though keep in mind not being beholden to shenanigans from said cloud companies (and interference from government entities!) is definitely worth something intangible.

I think 24gb is the bare minimum for a local qwen3.8 based setup. I've used qwen3.6 and it's not as straightforward as "can it replace <insert the most cost-effective cloud solution today>"
Local llms don't suffer from cloud availability issues. Anyone that used Google models know that sometimes they just don't have capacity whatsoever, at least that was the state of things some months back when I used them. Just bear in mind if needed, cloud providers will prioritise API and corporate customers over subscriptions if availability degrades more.
Also they don't have the same guardrails as the other models, so for hacking, reverse engineering and black coding (piracy etc...) these local models might be the only options.

The principle of KISS keeps coming to mind when I consider local computing. I'm looking forward to the day we can just run Opus-level models at 100 tok/sec on consumer hardware.
But currently it's really hard to beat anything offered by the cloud companies. And the cost and complexity of setting it all up, just to barely (if at all) touch on Opus-level intelligence makes it seem like we're not quite there for the common man (enthusiasts are a different story.)
I am very excited for open source local models, and we're nearly there, but it's still too complex and expensive to be my daily driver (yet).

Local setups aren't going to make sense purely from a cost perspective, and definitely not when you are buying Apple hardware. AI subscriptions are too highly subsidized right now.

I think your last point is exactly why I'm so interested in local models. The current landscape doesn't feel sustainable. The last few months we've seen the big providers (OpenAI, Anthropic) start to play with usage limits, resets, banked resets, pulling models, etc. I think local models are close to the point where, with a sufficiently well-architected harness, you can get results that are on par with the experience you'd have with cloud inference. It is nice to know that I have hardware under my desk that I control with open weight models that I can interact with on my terms.

yes, you have to unfortunately adopt a 2025 mindset when working with smaller local models because that's where they are compared to the frontier.

In my opinion, 98% of the work most devs would send to an AI can be capably achieved with a local model and a frontier-level model is overkill.
The goalpost moving feeds right into Anthropic and OpenAI's interests.

The article implies the demand is for running locally. I’m not convinced, at least with a mac minis. Most people I know and myself buy the mini as it is always on, easy to setup, and isolated from my main computer which is a laptop. The mini is driving the use of the $20/month subscriptions.

As a thin client to access cloud models this is an astounding waste of money.

One use case I find cost effective is using it as a voice assistant for Home Assistant. API pricing on models is very weird compared to the normal chats, so I use Qwen/GPT-OSS on my Mac Studio via llama.cpp server.

Could you elaborate on your experience with local models on your card? I've been thinking of upgrading to 9070 XT, and was thinking the 16GB would be okay-ish to at least run something usable locally, no?
fancyfredbot

Usable certainly. But my impression is that useful models still need a bit more than 16GB. Something like Qwen 3.8 27B is useful but squeezing it into 16GB requires fairly aggressive quantisation which will make it unreliable (e.g it'll get stuck in loops) and won't leave enough space for a long context (which qwen 3.8 really likes)

I’m the parent of this thread, the person with the with the RX 9070.
My understanding would be that if you’re interested in this sort of card for AI that you should go with the AI PRO R9700, which is basically the professional version of the RX 9070XT but with 32GB of memory.
It’s significantly more money but not crazy like a 5090.
I just happen to have the 9070XT primarily for gaming purposes.
I’m not quite sure how to describe my experience using it other than “rudimentary,” and a lot of that is on me for not really understanding the best way to set it up.

If you have been using cloud hosted models, you will be severely disappointed with what you’d be able to run on 16GB VRAM. You will spend most of your time fighting with the model to fix its mistakes.

I was getting semi-useful results from a 128GB M4 Max. That was a few months ago, and the models have improved (quite a bit) since then, but now I'm happy to send my $20/month to get Claude code.
It's still frustrating as hell to come down in the morning, having given it a list of tasks to do overnight, with tests to pass before they're "done" and find that it worked for about 20 minutes after I went to bed, and decided that it would stop at "3am" (it wasn't) and "not do significant work this at this late hour". Like WTF ? You're an LLM. You don't sleep.
Bloody training data full of humans demanding sleep. I tells ya...

Is this Claude code? Or your local? I assume Claude? I'm more than a little staggered by this, like, it makes no sense! It doesn't even serve Anthropic's interests (surely better for them if it burns your token quota so you have to buy more the next morning.) The LLM just... decided? I'd be so mad.
WTF indeed. Can one even file bugs?

Parent mentioned their $20/month subscription. It's definitely in Anthropic's interests for you to not use it.

I think that's Anthropic trying to get you to not extract as much value out of that subsidized subscription as possible.

I've been experimenting with local models on an M5 Max MBP w/ 128GB of RAM since March of this year. Generally I've had very good results. Where things were lacking initially was with tool calling and the need to rely on tool calling for functionality like web search, which is otherwise well integrated in the cloud models. There is also a lot more work required on the harness side, however at this point (August 2026) there is not only much better tool calling in local models, but community supported projects have built good harnesses. Pi.dev and OpenCode + a SOTA local model is /very/ /very/ capable these days. Using LM Studio's built-in chat with a decent system prompt and proper tuning with local models is /very/ capable these days. Cloud models are still better, but it's the "harness" (not in the desktop app, but in the backend) that makes it so for the most part.

IMO local models require a substantial amount of prompt+harness engineering to get in the neighborhood of what you'd get from a cloud model. Which isn't a bad thing, you'll learn a whole lot about how these things work.
What you'll learn pretty quickly from said engineering is that there's a lot more to a good LLM than just the weights themselves. You need a good search provider (also self-hostable, but sounds easier than it really is). You need (well, it's debatable) a memory system. You need a good system for up-to-date library references like a Context7 (also self-hostable but the options are surprisingly not that good). You need a good set of specialized subagents that can perform various tasks well -- for the sake of "doing things well" but also managing context efficiently.
When you've got all that, local models can be _extremely_ useful. But there's one other important thing and that's decent hardware, unfortunately. A lot of people try out local models using small consumer GPUs or Macs and are rightfully unimpressed with the performance. And if the performance doesn't get them, usually they have expectations that they'll perform at Claude levels out of the box. Getting in that neighborhood, like I said, definitely requires some work.

What you’re describing is exactly what I’ve experienced in my time testing out this stuff locally, and I had a hard time figuring out what exactly to blame.
I keep hoping that one day some comment is going to paste a link to some kind of idiot-proof guide or piece of software that’s “90% as good as Claude but running local.”
And by 90% I don’t mean that the model is 90% as good or runs 90% as fast, more like all the other stuff you mentioned is set up out of the box.

I have multiple 48GB friends that successfully run smaller quantized models for general assistance + light editing (coding, spreadsheets, etc), that don't require very heavy models.
So yes, they are genuinely very useful, but they are not yet a full replacement unless you have more powerful hardware and or don't need more intelligent ai.
