I've been running a quant/tune of Qwen3.8 27B on my M1 Max 32gb MacBook. That plus a good pi setup is having great results. I've used a full q8 of the model before and I dont see a real difference other than how slow it is. But leaving it running overnight on tasks is working great. It is currently debugging some issues in a native Mac Swift application and getting through the list of issues just fine.
This is the one that works good for me on 32gb:

Specifically this one: Qwen3.8-27B-GSQ-RCO-IQ3_S-mtp.gguf
I am running it on M3 pro. Works great except for prefill speed which makes it slow for many coding tasks. The newer generation of macs are promising but as a cost-sensitive user, I am also looking into cheaper 32 GB gpus from intel, AMD, nvidia. Eventually, I think these class of models will work well for most coding usecases especially given that I certainly want to have some control of the code generated.
