About the MacBook Air 13" M4 (32 GB)

The MacBook Air 13" M4 is a 32 GB laptop with more memory than speed: it runs 35B MoE models well. macOS keeps about 3.5 GB, leaving 28.5 GB for models. Prompt reading is its weak spot: a 4K-token prompt waits 23 s before the first word on Qwen3.6 35B A3B. M4 generation, released 2025; the newer M5 writes 28% faster with 1.9× the compute.

MacBook Air 13" M4 strengths and weaknesses

Strengths

  • Runs 35B MoE models: Qwen3.6 35B A3B at 23.5 tok/s in 22 GB

Weaknesses

  • 70B models don't fit: Llama 3.3 70B Instruct needs 51.3 GB at Q4 vs 28.5 GB usable here
  • Slow on large dense models: Qwen3.8 27B at 4.8 tok/s
  • Slow prompt reading: A 32K-token prompt on Qwen3.6 35B A3B waits 3.0 min for the first token
  • No CUDA: vLLM, AWQ, GPTQ and FP8 builds don't run; use GGUF or MLX
