I just got qwen 3.8 27b mlx running on my Macbook Pro and honestly I’m pretty blown away by how not-dumb it is.

It was actually great. I have like a non-AI box so to speak 8GB VRAM, co-incidentally from a gaming PC ...
All the previous models that were "frontier level, just try it!" but wouldn't run at all in agentic mode, including previous Qwens, just disappointed, period.
Then I ran then Qwen 3.8 27b and while it was super slow (4t/s) it literally one-shotted creating a usable "web search/pull" skill for `pi.dev`. while any other model previously just entirely failed to create anything usable even with actual guidance.
Since then I have actually gotten a gemma-4 12B qat 4bit quantized with a ~250MB MTP from unsloth to work with a 32k context "working" on this setup at 80-120 t/s. That's usable for private stuff on a co-incidental box!
It's still only 32k context and it's entirely dumb vs. our API paid at-work Claude Opus. But for entirely private local stuff it's totally workable without breaking the bank even after all these AI price hikes!. I bought this rig literally just for gaming a month ago.

I got the qwen 3.8 abliterated model running on my MacBook Pro M5 48GB and it's pretty nice having a local model that can do a lot of experimentation without rails.

My problem is how hot they run. I'm on an m4 pro. Do you have the same issue?

It’s hot and also LOUD and runs the battery down quick.
But I’m having a lot of luck just running things when I’m away from the computer and can leave it plugged in.
It starts going weird (unreliable and slow) with context over 80k so you have to pick tasks one at a time and baby sit a lot more than Claude. But it really is very capable and feels like there’s an intelligence there to talk to. Maybe gpt-4 level clever?
I have an m5 max 64gb and I think anything slower would be quite painful.

Who'd run this on battery?
Or do you mean kills the battery faster even when used while charging?

There was a lovely window of a few years when processors were fast enough and low-power enough that real development work could trivially happen on a Macbook Air in a lounge.
That window is waning as more and more memory and graphics processing power is being used locally.
I suppose the future is most likely going to involve farming out AI requests to your desktop machine, your company's compute farm, or a cloud endpoint, but if you're expecting to run an AI offline on your lap with a battery...your lap will get warm.

Running the laptop hot ages the battery even when you’re plugged in.

I remember doing this with crypto mining way back in the day. That machine will die within a year.

I have an m3 max 64GB and it runs ok, I was playing around with it last night. Its reasoning is better, but the token/s still makes an MoE model (35B A3B) preferable so I switched back.
Try using Goose instead of Claude's harness? Goose doesn't load as much context in at the start, so it might be more usable. I've definitely been able to get it past 128K, although I typically don't go beyond 70-80k. MoE might also be better at this.

Macs fan control set to full blast and lifting the Mac above table for air circulation across bottom.
I use M1 Max with qwen3.8 27b mlx. The gpu temp can reach easily to 95°C as fan doesn’t kick in automatically until 90°C. With Macs fan control at full blast and MBP off table, temp usually hover around 85°C.

Yikes isn’t 95 well above the danger zone for most components or have things changed? I remember crypto mining in the early 2010’s and making sure to stay under 85C on my GPU.

If you're going to try to use a mac laptop for long term inference you'll probably want to buy one of those $30 laptop fan cooling pads (sold for absurd sized 17 inch x86-64 gaming laptops) on Amazon. Otherwise you'll roast the battery over time and significantly hurt its cycle life and capacity. If you can get significant airflow under the laptop that'll help a lot.

I don't have the hardware but a often mentioned advice is to put your mac into energy saving mode - it still will work, a bit slower, but stays cool.

I tested Gemma 4 a couple months ago and yes it ramps the fans to max. Definitely a thing that should only be done on wall power.

My M4 Pro 48GB gets about 13tok/s, in both 3.6 and 3.8 27b Qwens. Qwen A3B and Gemma get closer to 100tok/s from memory but the results are pretty poor for coding tasks.
Edited to add: for agentic workflow I’m running omlx which tells me it has about a 90% cache hit rate (tradeoff is some disk and mem space) - that noticeably changes the felt speed.

Seems threads about local LLMs on Apple hardware feature comments listing M3/4/5 at 48GB 64GB and not 128GB.
That is, users with M-series hardware that have less-than-max RAM share results whereas users with max RAM do not.
Speculating (not extrapolating), maybe users with machine that have max RAM are less interested in running local LLMs and are less averse to paying services for compute?
Personally, I’d love to see what output max RAM M-series Apple hardware in these threads.

Qwen3.8-27B runs at 59.5 tok/s on my M4 Max, 40-core GPU, 128 GB
I use it occasionally for classification and other tasks but I wouldn't trust those smaller models with the real work and for larger data processing it's too slow, e.g. a dataset I wanted to classify would've taken 56 days on my laptop vs just paying the cheap Luna prices to openai and getting it done in a few hours.

Not sure I would trust Luna with that. Deepseek Pro Max and Code Mode I would be more inclined to trust.

I feel like it's 50/50 between people doing that, and people that have spent a lot of time tuning a system they are pointing at focused and well specified problems.

Yeah, that's my experience. It's a big "wow" factor to get a non-trivial LLM running on my Mac, but it's actually not that useful. Like trying to use Photoshop at 8 FPS.
coldtea

Regarding this analogy, fps don't matter as much for Photoshop, since it's not an immediate mode GUI. 8 fps would be quite ok for comfortably getting feedback on live image filters and such.

I tried it on my M1 MacBook Pro. It's slow but surprisingly smart as a general purpose LLM. Maybe GPT-5.3 level. I gave it a bunch of tools and it can search the internet, make product recommendations, document, code, etc.

Had the same reaction so had Grok create a script to:
- find a free GPU droplet on digital ocean
- fire it up
- pull in a snapshot of the model + extra files/packages etc
- set up a ssh tunnel so that the localhost:8000 routes to the above
Then I just configured OpenCode to use the above and was off to the races.
Works out to be about ~$2/hr all said and done which isn't bad as I only pay when I'm using it (but could get expensive with 24/7 running)

What GPU you end up with for that price? Vast.ai (https://cloud.vast.ai/?priceInstanceHourlyMax=2) has a bunch of setups available to reach 192GB VRAM under $2 :) Quick skim showed 4x48, 2x96 and 8x24, all for under 2 buckaroos or around there.

Awesome, I used Claude to write a small python script to do the same with Linode's API. The only difference is I setup a persistent drive, and with Linode you can boot off of it. So my biggest start up lag is ~ 2 minutes to deploy + boot, then maybe 2 more to warm the model.
I actually dislike LLMs. But I'm a realist, and on-demand compute like this is massive cost saving measure.
(persistent drives are relatively cheap, compared to a box with several GPUs.. or even one. I find it worth the expense)

Does it need to respond fast? For important applications, I'm sure we'd all be fine waiting 20 minutes for a high quality, usable answer. Or is it the need for interative refinements that make speed relevant?
jonplackett

It requires patience but it’s more like waiting 5 mins for it to do tasks. You need to be much more involved though and do things slower than Claude where you can trust it to do a lot of tasks at once. It doesn’t have the context for that
