Why bother with local LLMs?
Posted by West-Currency-4423@reddit | LocalLLaMA | View on Reddit | 39 comments
Tomorrow, I am getting delivery of a 13" M5 macbook air with 32gb RAM and 1T SSD. Currently, I have pro subscriptions to Gemini, Perplexity and £15pm Claude.
My question is why go for local LLM instead of the cloud? If it is cost, aren't frontier model costs coming down for the same level of intelligence? And what about how much intelligence my 32gb could provide in 6 months, a year, or 2 years time?
I'm sure many people have the same sorts of questions and doubts as I do.

For me the big reasons are control, data boundaries, and latency.
With a local model I know exactly where tokens and logs live (on my disk, in my network). That matters a lot once you start putting work docs, customer data, or codebases into the context window.
I can enforce my own permission model for tools (shell, DB, browser, etc.) instead of trusting a hosted product’s defaults. For example, I can say “this agent is allowed to read from this folder and run these 3 commands, nothing else.”
Latency is also underrated. Having the model and tools on the same machine (or same LAN) makes multi‑step agents feel much more interactive.
Cloud is great when you need the biggest frontier models or don’t care about where the data goes. Local starts making more sense when you care about sovereignty/compliance or you want to treat the agent as part of your own infra rather than a SaaS you have to trust

The reason people choose local LLMs instead of cloud models is not as simple as cost, even though cost is part of it. The deeper reason is control. When you run a model locally, everything stays on your machine. Your data, your prompts, your workflows, all of it. Nothing is being sent to an external server. That matters to developers, researchers, and anyone building systems where privacy, reliability, or independence is important. With cloud models you are always tied to a provider. They can change pricing, limit usage, update the model silently, or introduce rate limits that affect how you build. Even if prices continue to drop, you are still working inside someone else’s system.
Cloud models are still ahead in raw intelligence today. The best frontier models are more capable in reasoning, writing, coding, and general problem solving. They also tend to be more consistent and better at handling complex instructions. However, the gap is not static. Over the past few years, the cost of intelligence has been steadily dropping. You can now get models that were once “frontier level” for a fraction of the price or even run similar capability locally in smaller form. That trend is real and continuing. The important detail though is that even as prices drop, heavy usage in cloud systems still scales with how much you use. If you are building automation, coding agents, or multi step workflows that constantly call a model, costs can still grow quickly. So even if the price per token is lower than before, the structure of metered usage still matters.
Local models solve that problem in a different way. You pay once for hardware and then your usage is effectively unlimited. That changes how people design systems. Instead of worrying about every call, you can run loops, agents, background tasks, or constant experiments without thinking about a bill growing in real time. The tradeoff is that you are working with less raw intelligence compared to the top cloud models, but you gain predictability and independence.
With a 32GB machine, what you can run today is already more powerful than most people realize. The most comfortable range is around 7B to 9B models. These run smoothly and feel fast. They are already useful for coding help, writing assistance, summarization, and general reasoning tasks. They are not “toy models” anymore. They are genuinely productive tools if used correctly.
The next step up is 13B to 20B models. These often require 4 bit or 5 bit quantization to fit comfortably in memory, but they provide a noticeable jump in reasoning ability and instruction following. This is where local AI starts feeling closer to older cloud models from a couple of years ago. They are still fast enough for interactive use, but you begin to notice more latency depending on your setup. Even so, this range is often the sweet spot for many users because it balances intelligence and speed well.
At the upper end of what 32GB can realistically handle, you have the 30B to 34B range. These models push the limits of the system and require more aggressive quantization. They can be significantly smarter in structured reasoning and planning tasks, but they are slower and more resource intensive. This is the point where you really feel the tradeoff between local convenience and cloud-level performance. They are usable, but not always comfortable for fast interactive work.
Beyond that, such as 70B class models, you are generally outside what 32GB can handle in a practical way without heavy compromises. They can sometimes be made to run with offloading techniques, but the experience tends to be slow and not ideal for real time use.
What is important to understand is that model size is not the only factor anymore. A well optimized 13B model today can outperform older larger models simply because training techniques, datasets, and fine tuning have improved. The intelligence per parameter is increasing. That means smaller models are becoming more capable without needing to grow in size.
Looking forward, the next six months to two years will likely bring more improvement in efficiency than in raw scale. Local models will get better at doing more with less memory. Quantization techniques will preserve more intelligence while using fewer resources. Context handling will improve so models feel less limited in longer conversations. And smaller models will continue to close the gap with mid tier cloud systems in many practical tasks like coding and structured reasoning.
However, it is also important to be realistic. Frontier cloud models will likely remain ahead in absolute capability for some time because they benefit from large scale training resources and infrastructure that cannot be replicated on consumer hardware. But the gap that matters for everyday use is shrinking. For many tasks, especially development, automation, and personal productivity workflows, local models are already becoming “good enough” that cloud usage becomes optional rather than required.
So the real picture is not a competition where one replaces the other. It is more like a split. Cloud models give you peak intelligence on demand. Local models give you control, privacy, and unlimited usage with steadily improving capability. And with something like 32GB of RAM today, you are already in a space where local AI is not experimental anymore. It is practical, usable, and increasingly powerful, with a trajectory that suggests it will only get better over time.

Opus 4.5 was the game changer for me, but since building my own harness I've found that sonnet is more than capable of the coding, planning, and reasoning tasks I feed it. So I'm thinking we're reaching a point where local models will do just fine - massive cloud models will still keep improving, but I'm not sure we'll need that for most things. A couple more months of the kind of innovations we've seen lately will see sonnet level performance in under 128gb I reckon.

After playing pretty extensively with the gemma 26b/31b models, I wouldn't be surprised to see Opus 4.5 level performance on 24gb vram cards soon. We're already basically hitting 1-year-old SOTA on the home cards, when a couple years ago the models we could run at home were absolutely awful. Same cards, huge advancement.
There's a massive amount of built-in userbase in the 24gb vram range going all the way back to p40 teslas (and 32gb thanks to the 5090), meaning enthusiasts will target these sizes well into the future and try to squeeze out frontier performance.

This question has been asked a million times on this sub.
Most people should not use local LLMs, just like most people should not use Linux or write code.
Initially, this sub was made up only of people who used local LLMs, but now there are many people who use Chinese cloud models (and they often hate local LLMs).
rhinodevil@reddit
More people should use Linux! :-) But I get what you mean.
juss-i@reddit
Adding to this. If you can't think of a reason to run an LLM locally, you likely belong to the majority who shouldn't.

I am writing a sci-fi novella as a hobby and it's a hard variety of sci-fi. To better research the topics I was covering I quizzed ChatGPT on a few bio-med engineering problems and unfortunately it blocked my enquiries. Similar thing happened when I tried to colorize my own early childhood photo from a beach with my father - request denied.
If you trust the companies to act in your best interest for the money you're paying and you care about the bleeding edge tech - it makes sense to use cloud. If you have other priorities - even if you don't want to spend 8k on a workstation and a mid model, you can still use a huge open weights, abliterated model, hosted on a rented baremetal machine somewhere and have full control at a fraction of the cost.

privacy. I dont want to think about details like logins, api tokens or details about what i am doing while working with a llm

Ok_Technology_5962@reddit
Yea and learning how they work is seriously helpful. You forgot on using spliced models like qwen 3.5 40b etc... getting the flavour you like from a model. - Like maybe the amount of words isnt high enough so have it spit out 100k instead. - Knowing which tokens you syont like and banning them. - Changing system promp so models talk in a way you preffer like o3 for example.

I like the ability to have uncensored models because it is frustrating for the LLM to not answer the question for politically correct reasons.
What is the worry about privacy? Surely your data is just in a sea of billions of users. No one cares and no one is likely to see your individual data, or at least a tiny fraction of risk.
Onekage@reddit
Of course it is a personal preference, but your data, as an individual, matters to them more than it probably matters to you. Plenty of multi-million dollar acquisitions were solely because of user data, not the technology (lookup the Frank and JPMorgan case).
West-Currency-4423@reddit (OP)
But in a world where they cannot see what people want they cannot provide what you want. And this can lead to companies not surviving. You get free stuff because companies use data to make a profit. And your individual data point does little to shift the needle due to the law of large numbers. Collectively amongst tens of thousands of people it might give behavioral insight but then that is conflating one data point with thousands or millions. That is irrational to argue your data point gives insight into the collective masses.

Basically, you can run your computer 7/24.
West-Currency-4423@reddit (OP)
I like that idea. I have openclaw and I would never like to leave it connected overnight to autonomosly burn through an unpredictable number of API credits.
esadomer5@reddit
Lets go higher,
If you buy 8xH200, you can setup GLM-5.1. So you have almost sonnet-4.6 intelligence on your computer and you can run it 7/24.
West-Currency-4423@reddit (OP)
Maybe in under 2 years time we can run GLM5.1 level intelligence in 32gb. Then my laptop will be King.
Objective-Stranger99@reddit
Deepseek R1 had intelligence equal to that of frontier models when it launched. Now Qwen3.5 35B matches or beats it on most benchmarks at a fraction of the size. Right now, GLM 5.1 is at the same point as Deepseek was a year ago. So by the start of next year, we should have GLM 5.1 intelligence under 32 GB.

Hope it happens before the rugpull
Due_Net_3342@reddit
just wait the bubble to pop, that 15 dolar subscription will be more like 150-200. And yeah, with your low ram you cannot run anything decent, you need to upgrade to at least 64gb
West-Currency-4423@reddit (OP)
But aren't model sizes shrinking by 50% every 3 months?
Yes-Scale-9723@reddit
for a flagship-level performance you need at least 700b parameters
david_jackson_67@reddit
Not any more.
Ok_Technology_5962@reddit
I feel like you are misunderstanding and not using them to the limits. The small models will get better yes but the limit is always there im a gemma 4 hyper but even i know glm 5.1 is a monater compared to Gemma. The trend doesnt show small will pass large just that the both inceease in capability
viperx7@reddit
I feel the opposite is happening can you tell me where are you getting this from
West-Currency-4423@reddit (OP)
Multiple sources including from frontier ceos. Also, look at Gemma 4 as an example.

The privacy concern isn't just about your data being individually "seen" — it's about behavioral inference at scale. Companies aggregate billions of interactions to build user profiles, improve their models, and predict behavior patterns. Your individual risk might be low, but you're a data point in a system designed to extract value from usage. With a local model, there's nothing to aggregate because nothing leaves your machine.
For power users running 50+ queries a day, that's a meaningful difference. And regarding uncensored models — you get exactly what the model produces without alignment filters shaping outputs.
West-Currency-4423@reddit (OP)
I want companies to use our data to do behavioral inference at scale. This is how they improve the LLMS with reinforcement learning.
I do like the lack of filters argument.

Go look at the Claude sub to see how everyone complains about Anthropic changing stuff all the time. You know what doesn't change? Your local model.
West-Currency-4423@reddit (OP)
True!

Real reason.
It's just because it's fun, like buying a ps5.
