Is the Mac Studio M5 good for running local AI?
Short answer: Yes, mainly because of unified memory. Apple lists the M5 Max Mac Studio with 36 GB standard (up to 128 GB), and the M5 Ultra starting at 96 GB, configurable to 256 GB or 512 GB. More memory means bigger local models.
| Chip | Unified memory (Apple specs) |
|---|---|
| M5 Max | 36 GB standard; 48, 64 or 128 GB options (128 GB with the 40-core GPU) |
| M5 Ultra | 96 GB standard; 256 or 512 GB options (512 GB needs the 80-core GPU) |
What fits, roughly
A model at 4-bit needs a bit more memory than its file size. Qwen3.6-27B at 4-bit is about 16-19 GB (third-party estimate), so 36-64 GB is comfortable for it plus your apps. Very large MoE models need the Ultra.
Before you spend
- Try the model on what you have first with Ollama.
- Memory can't be upgraded later. Buy for the biggest model you really need.
- Compare against a few months of a cloud plan: see free AI options.

Do I need a Mac?
No. A PC with a 24 GB GPU or a Linux server works too; see Linux setup.
