Entry local AI Mac. Fine for 7B–8B class models via Ollama/MLX. Not ideal if you want 30B+ resident — step up RAM.
Macs for local AI
Answer: Buy by unified memory, not just chip name. Most local LLM desks want 24–32GB (M4 Pro mini or used M2 Pro mini). For models that will not fit a 24GB GPU, look at 64GB+ Studio. GPUs still win raw tokens/sec — see Mac vs GPU.

Sweet spot for many local LLM users: 24GB unified memory, quiet, low wattage. Strong MLX/Ollama inference for mid-size models. X community default for 'private AI on a desk'.

48GB unified memory rivals workstation VRAM for model size without a discrete GPU. Best mini config for larger local models if budget allows.

Used-market favorite: 32GB unified memory often cheaper than new high-RAM M4 configs. Excellent value for local LLMs if you find a clean unit.

64GB opens larger models and longer context than any 24GB GPU. Used Studios with high RAM are the secondary-market play for serious local AI without NVIDIA.

Ultra bandwidth + 64GB for heavy local inference. Check eBay carefully for config (base Ultra often ships with less RAM — buy the listed memory tier).

Current-gen Studio Ultra. Buy by RAM tier first (96GB+), not just chip name. New/refurb Amazon + used eBay both apply.
