Can MacBook Air M4 16 GB run MiniCPM5 2B?

16 GB unified · 120 GB/s memory bandwidth · MiniCPM5 2B has 2.5B parameters.

Short answer

Yes, excellent for chat and acceptable or better for every workload we test.

Best quantization for chat: Q8_0 (2.5 GB of weights) on LM Studio. Generation: 25–35 tok/s, leaving about 4.8 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.
