Apple MacBook Air (M4)
No editorial image yet — generic vendor mark shown. Credentials in spec table below.
The cheapest portable Apple unified-memory machine and a common 'try local LLMs on a laptop' entry point. M4 with 16/24/32GB at 120 GB/s, fanless. Runs 8-14B models well in bursts; sustained loads throttle.

What it does well
The M4 MacBook Air is the most approachable way to run local LLMs on a laptop you'd actually carry. Unified memory means a 24GB Air handles 8B and 14B models that would choke a Windows ultrabook with a tiny iGPU, and MLX/Ollama make setup trivial. At ~30W and fanless, short interactive chats and coding-assistant bursts feel snappy, and battery life under light AI use is excellent.
Where it struggles
It is fanless — the defining caveat. Sustained generation (long documents, batch jobs, extended agent loops) heats the chassis and the M4 throttles, so steady-state token speed drops well below what a Mac Mini or Studio with active cooling holds. 120 GB/s bandwidth also caps larger-model speed, and the base 16GB is tight after the OS. It's a burst-inference machine, not a workhorse.
Bottom line
The right pick if you want local AI on a thin, silent, all-day laptop and your usage is interactive rather than sustained. For heavy or continuous local inference, a cooled Mac Mini/Studio (or a discrete-GPU laptop) is the better buy — but nothing else this portable runs 14B models this easily.
