No. Even at Q4_K_M, Qwen2.5 72B needs about 47.4 GB, but the Apple M2 Pro (32GB) has 21.4 GB usable. You could offload some layers to system RAM, but it will be very slow.
Run it on a rented GPU
On a cloud GPU with enough memory, the same command you'd use locally works:
ollama run qwen2.5:72bAt Q4_K_M it needs about 47.4 GB, so pick a GPU with at least 48 GB.
