My local model setup on an M4 Pro Mac Mini

    No mention of the performance of the models? I'm able to load a bunch of different models on my little mini-PC with 16GB RAM, but the performance is terrible. I always wonder what performance people are getting with local models that they find is acceptable?

      I honestly wouldn’t bother with local models right now unless I either had a 5090 and was happy with running Qwen 3.8 27B, or a pair of DGX Sparks running DSv4 flash or better, 2x6000 RTX Blackwells. Those are the kinds of rigs that the local model enthusiasts are running. With those setups, you’re looking at generally >100tps generation in single stream, and 10s of thousands per second of prefill, so it’s snappier than Claude code, which somewhat makes up for it being dumber.

      That said, it is really cool to be able to run an LLM on eg a Mac laptop. Just not a better experience on almost any metric for interactive use than eg Claude Code, beside privacy and guardrails.

      It’s not. Do it as a hobby or for privacy but for performance just use a frontier model api. You’re paying less than cost for something that would take tens of thousands to set up locally.

        It does make me wonder how the hosted stuff is so cheap. For pretty much everything else, hosted/rented is more expensive but offers better convenience and flexibility. But for AI, even if you consider the total lifetime cost and are utilizing it heavily. You never break even by buying.

          There are economies of scale but there’s also a data center bubble (probably) so there might be some selling dollars for fifty cents going on.

      I run a similar setup to the one he described on similar hardware. I run bifrost and llama swap though (tailscale rocks). My local model usage is for some out of band batch processing one of my personal apps uses. Basically a personalized recommender for media, it curates stuff for me based on a database i've compiled over years, so non-interactive. For that use case, I don't really care that it might take a few minutes to run. It's free. The machine is just sitting there anyway. I have tried using qwen-coder and opencode on my M5 Max 128gb and compared to claude code it's painful. I did setup a workflow where claude plans, qwen executes (unattended overnight, again b/c it's slow) and then claude reviews. I benchmarked this several times and I ended up using MORE tokens with claude because it had to 'fix' all the qwen issues. While the code it produced was 'good enough' the fixes were worth it so I just stick to coding task using API models (codex and claude).

      I have an M4 pro (48 GB ram) and I run Gemma 4 26b a4b at 52 tok/s and Qwen 3.5b a3b at 72 tok/s. Both 4bit quantized. These are enough for my needs and the performance is more than good enough. I'm not running the MLX version of the Gemma model, if I did the inference speed would likely be a bit better. I wouldn't use them for coding features though.

    I tried the 1 bit model of Qwen3.6 27B on my M1 pro and got 13 tok/s with only 5G of ram usage.

    M4 Pro has been a solid performer for iterating on smaller local models. Much more convenient than spinning up cloud instances for dev.
  • max979 23 minutes ago
    That M4 Pro is probably a beast for quantised models. My M2 Pro handles 34B just barely; what speeds are you seeing?

    My biggest problem with running local LLMs on my M4 Max/128GB RAM is the prefill latency.

    I've since acquired two DGX Sparks, and it feels so much snappier.

      m5 max really fixed pp with the better matmul support, im sure the m5 ultra will be even crazier

      the sparks have much slower memory bandwidth is the trade off

    I have an m1 Mac 64gb and look forward to trying this out

    Not many people share setup with actual setup handholding so that was very G of you

  • xydac 41 minutes ago
    yes, share performance, numbers if you can, also i wonder if you figured out a way to do a 2way audio with local models, or even explored that. I have a very similar setup but not too happy with the token speed, will try omlx though !!!

    Have a macmini m4 32G, not the pro version, previously everytime I tried local LLM is a bit disappointing, and I finally decide to not waste time and perhaps in the future invest a better hardware to server more modern and dense model

    I am curious is what is the 80% request served by this setup, I was using it for OpenClaw which run serveral cron jobs that discover stuffs over the wide internet, check my support system's unanswered tickets, browser X and some social media for me to filter the valued ones(though I have to say even with GPT 5.6 sol, the quality is low for the timeline X sent to me)

    Btw, Tailscale is quite cool and did a good job, I was using it to serve the local LLM and connct the openclaw on a Linux Machine to it.

      You have tried Qwen 3.8 27B before coming to this conclusion, I hope? It's an incremental improvement over 3.6, but I mostly want to make sure you didn't just try running some old junker before coming to this conclusion.
