Can MacBook Air M3 16 GB run Qwen3.5 9B?

16 GB unified · 100 GB/s memory bandwidth · Qwen3.5 9B has 9.7B parameters.

Short answer

Yes, comfortable for chat; borderline for coding questions.

Best quantization for chat: 4-bit (5.2 GB of weights) on LM Studio. Generation: 12–16 tok/s, leaving about 2.0 GB free for your other apps.

How it rates for each workload

Same model and machine, different jobs. Agents and long documents send far bigger prompts than chat, so they need much more speed and memory.

Get it running

Copy-paste commands for the 3-bit build with a 64K context. Ollama and llama.cpp download the file straight from Hugging Face.

ollama run hf.co/unsloth/Qwen3.5-9B-GGUF:Q3_K_M

Downloads 4.67 GB (Q3_K_M). Ollama's default context is small: set OLLAMA_CONTEXT_LENGTH=65536 before `ollama serve` for long prompts.
