But you have to factor in that this device will last you 5-10 years. That said, I wouldn't spend almost $7k USD on this macbook lol.

Memory requirements of newer models will increase, so while the hardware may last 10 years it won't be able to run the latest models for 10 years.

Available models aren’t really trending upward in size. Not like I thought they would, anyway.

They’re trending to be the right size to be good.

Qwen3.6-35B is not as good as Qwen3.6-27B. The larger model is faster, but a lot dumber; it gets caught in loops, makes crazy mistakes, and is just not as good. It’s bigger, but it is nowhere near as good as the 27B variant.

I opted to buy a normal 32GB laptop for this very reason. I know how loud and hot the GPUs in my desktop run when running even smallish models like Qwen 27B or Gemma 4 31B (which is a better model for most than Qwen 3.6, despite the benchmarks). I also have a Strix Halo which doesn't get loud, because it has a single huge fan, but it does get hot. So, there's no way a laptop could work as hard as models make them wor…

Gemma is better than Qwen at everything except coding, in all my evaluations. Which is a shame because that is what I use them for!

It would be great if the Gemma folks would release a code-focused model. Probably won't happen, but it's fun to dream.

Would the new upcoming AMD AI ryzen halo desktop be a better value offer? or dgx spark? You would have to get a third party reseller/scalper or refurbished mac mini to get 64gb of ram ever since apple stopped selling it.

I'm currently fiddling with a DGX Spark and Qwen3.6-35B-A3B (specifically Qwen3.6-35B-A3B-NVFP4 under vLLM, with EAGLE3 speculative decoding via eagle3-dogacel-vllm), and it's pretty okay in terms of smarts. The speed is relatively usable at about 50 tok/sec with a 256k context window, and it's definitely smart enough to one-shot some basic coding tasks. I had it doing reverse engineering/disassembly of some ancient…

Looping is a common problem with the Qwen models. I've had good luck using --repeat-penalty=1.1 with llama.cpp and 27B. vLLM should have a similar option.

Has anyone managed to cleanly integrate Web search into local models (run with llama.cpp)? The biggest limitation of the class of models that fit into one or two consumer GPUs is that they lack world knowledge, but presumably this can be remedied by enabling access to use the Internet.

Buy a refurished or 2nd hand one.

Also not really available.

Especially with anything resembling a usable amount of RAM. Mac Minis and Studios >=64GB are basically permanently sold out everywhere, because everyone, including commercial entities with deeper pockets than most of us plebs, has the exact same idea at the exact same time.

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…

In general if you're setting up a local LLM you should assume it's going to be primarily working as a server and talking to various clients. I use my MBP, but that's because I don't travel much anymore so it can happily work as a server at all times. With the right agent setup you can probably manage most things from your phone even if you don't have a seperate machine to use as a client.

I have an older laptop I run a hermes agent on backed by an API based open (non-local) model and Macbook Pro M4 for running another model locally (also using hermes). The agents have a Mattermost (open source version of slack) server they run and I run Mattermost on my phone so I can talk to them and task them with things. In fact, it was through the hermes WhatsApp endpoint that I got the first agent (non-local) to setup the Mattermost server and unboard the second agent (local mbp).

Then I can just chat with them through Mattermost when I need work done. Whenever I need something done I just hope on the Mattermost server and chat with them. I've had them build me multiple research reports (the fully local agent did awesome at this), learn how to use Stable Diffusion on my desktop to generate images, install and perform maintenance on various local services I run (including Open WebUI).

Same. And your M5 has acceleration that I don’t with my M3 max. I can’t do anything local it gets hotter than an Intel Mac trying to run docker from back in the day.

why not buy one of those "a.i" desktop kits being sold by Nvidia/AMD and just connect to them via network ? to me that's cheaper than paying an LLM provider such as Anthropic spreading FUD around open weight models & more sustainable too.

It's still currently way cheaper to pay open router to run qwen for you. And you have the option to use much bigger better models like DeepSeek v4 flash.
