About the MacBook Air 13" M3 (16 GB)

The MacBook Air 13" M3 is a 16 GB laptop with more memory than speed: it runs 9B models at 11 tok/s. macOS keeps about 3.5 GB, leaving 12.5 GB for models. Prompt reading is its weak spot: a 4K-token prompt waits 56 s before the first word on Qwen3.5 9B. M3 generation, released 2024; the newer M4 writes 12% faster with 1.0× the compute.
