I feel like I'm going insane seeing people buy these 128gb MBP for thousands of dollars to run models that are objectively much worse than SOTA and spending so much more. The amount spent on a 128gb M5 MAX can buy you a damned new car here. What the hell am I missing? Are developers in other countries living in such different worlds? (I'm aware the price is, in absolute terms, more expensive where I live compared to…

I also don't understand why people in this price bracket are buying Mac laptops instead of desktop computers with GPUs? Just to flex that it's portable?

I have a bunch of computers and gadgets, why settle on one?

I can't speak for the US, but in Germany (where hardware is usually more expensive, not less), I got my 3090 3 months ago for 750 euro and have been running the iq4_nl 27B using q4 kv (which after recent patches in llama.cpp is in my xp indistinguishably accurate from q8 of f16) at full ctx, with MTP at 2, peaking around 70 t/s on small ctx, around 50 t/s when im around 64k and ends around 40 t/s near the cap. The re…

I can't find a 3090 for less than 2k CADs (or 1200 eur). Is this the average price in Germany? It's pretty cheap.

I'm also curious, as this could pay for a trip out there, especially if buying for friends.

I love my MacBook Pro M5 128GB RAM and I love qwen3.6. BUT DO NOT buy this MacBook if you plan on doing serious coding using local LLMs with it. The reason is simple: your fingers will burn and your head will explode from the noise. Running any kind of sophisticated job on the very laptop you are using is just not viable. Sure you can use it in clamshell mode, but forget touching it while working with AI coding or ag…

Apple does not currently sell a Mac Mini with 64GB RAM.

Get a 2nd hand one. I was lucky enough to get a new one first, last week I get a 2nd hand one in order to run one of my Hermes minions at work.

The article is based on running Qwen 3.6 on a 128GB MacBook Pro. For reference, a 128GB MBP currently starts at $6699 USD [0] Some people will be happy to pay that premium for privacy, but at roughly 10X the cost of a MacBook Neo, that money could also buy a lot of credits on OpenRouter or frontier labs.

Oh definitely. I've seen GLM 5.2 go for around $4 per million output tokens.

What sort of M5 are you running? A max? MacMini's don't offer max CPUs.

The maths there is pretty undeniable, but it is not where I'd make the split. Having a machine that can run some modest local LLMs, like the Gemma 4 12B, is really worth it. I don't know how much serious hands-free agentic coding I will ever do on my MacBook alone, but I do know that I would not have got so far into understanding this without tinkering with local models, llama.cpp, LM Studio, and LM Studio and all th…

Exactly. The distinction between the various layers in "AI" systems is pretty vague to the newcomer. What is the "model" vs. the engine "running" it vs. weights?

I don't recall any previous tech stack that was barfed onto the scene with so little background or reference material, going from zero to endless undefined jargon... and no primer in sight.

For people who demand an understanding of their tools, it's a lot of work. I recognize the value of "AI" in performing the tasks I'd have to do manually; for example, keeping the data structures of my front- and back-ends in sync in a project. But do I want to interrupt my development and take weeks off to digest all of these tools?

And if I do, I want to run the show and fully understand it. And like you, I think that's best done locally.

> Having a machine that can run some modest local LLMs, like the Gemma 4 12B, is really worth it. Agree having a powerful machine is really worth it in general for professionals, but strong disagree that running local LLMs has anything to do with it. It's hard enough as it is getting a good ROI on your time/money prompting/wrangling with frontier models. IMO leaning on the comparatively limited capabilities of local…

I'm not that bothered about my coding skills, which are fine, and pretty up-to-date considering I'm now an old bloke. I am bothered about building an instinctive understanding that helps me deal with my anxieties and decide whether I want to carry on with this working life or quit.

I needed to do this, this way, in my own time, to put my brain back together. It has worked for me, which is why I recommend it.

YMMV.

I don't understand the talk about how expensive the hardware is. These models can run on very old or old and low end. I've been running Qwen3.6-35B Q4 on an old 1080 GPU(8GB vram) with 32GB sys RAM. I have a i7-12700.

It does about 30 tok/s which is enough for me. It's about half what the online models do, but it's enough.

I've heard their 9B models are also good, but they aren't much faster if you have the ram and a nice cpu.

These qwen3.6 models are the first ones I find can do much. GPT OSS was good, and Gemma4 is better. Gemma knows more facts, but qwen3.6 is smarter.
