Apple MacBook Air M3

The MacBook Air M3 is the previous-generation Apple Silicon ultraportable, now available at $749-899 with 8 GB unified memory (16 GB upgrade available). It runs small local AI models via MLX - 3-7B models work, but the 8 GB base memory limits context sizes and prevents running any model larger than 7B. The M4 Air is a better value at similar prices.

Quick verdict

Only consider the M3 MacBook Air for local AI if you find it deeply discounted. The base 8 GB model struggles with even 7B models at reasonable context sizes. An M4 Mac Mini at $529 offers better AI performance for less money.

Spec breakdown

  • Memory: 8 GB unified (16 GB optional)
  • Memory bandwidth: 100 GB/s
