The MacBook Air 13" M5 is a 32 GB laptop with more memory than speed: it runs 9B and 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 12 s before the first word on Qwen3.6 35B A3B. M5 generation, released 2026.
MacBook Air 13" M5 strengths and weaknesses
Strengths
- Runs 35B MoE models: Qwen3.6 35B A3B at 28.6 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 6.2 tok/s
- Slow prompt reading: A 32K-token prompt on Qwen3.6 35B A3B waits 1.6 min for the first token
- No CUDA: vLLM, AWQ, GPTQ and FP8 builds don't run; use GGUF or MLX
Memory for models
28.5 GB of 32 GB70B models need 51.3 GB at Q4, more than the 28.5 GB available.
Other memory sizes of the same machine first, then machines and GPUs people weigh against it, each with the one reason it is worth a look. Speeds on Qwen3.5 9B.
Output speed depends on memory bandwidth (154 GB/s). Grey rows need more than the 28.5 GB available.

Estimated speeds: Q4_K_M, 4K context, one user. How we estimate
Chip generations: writing vs compute
M1 → M5Writing speed follows memory bandwidth and barely moved: 7.5 to 16.9 tok/s since the M1. Compute, which sets how fast prompts are read, grew 3.1×. Indexed to the M1; speeds on Qwen3.5 9B, same 16 GB.
