Can I Run Cogito v1 on Mac mini (M4 Pro, 64 GB)?

Written by Jakub Rusinowski · Last updated March 20, 2026

Yes — comfortably

Yes, comfortably — Cogito v1 70B at Q2_K needs about 26.5 GB of the 48 GB usable on Mac mini (M4 Pro, 64 GB), leaving ~21.5 GB spare and running at ~6 tok/s (estimated), with room for about 65,536 tokens of context.

Confidence: high · Recommended quantization: Q2_K · Estimated speed: ~6 tok/s

Cogito v1 70B	45.7 GB	✓ Fits	~3.4 tok/s
Cogito v1 32B	22.3 GB	✓ Fits	~7.2 tok/s

Cogito v1 3B	3.6 GB	✓ Fits	~54.8 tok/s

What to watch out for

Q2_K is the only quantization that fits, and it is a heavily degraded one — expect noticeably worse output than the same model at Q4_K_M. A smaller model at Q4 is usually the better trade.
Memory on this machine is not upgradeable, so the configuration you buy is the ceiling for every model you will ever run on it.

Mac mini M4 Pro 64 GB limitations

M4 Pro memory bandwidth is half the M4 Max's, so large models that fit will still generate roughly half as fast.

Recommended setup

Ollama or LM Studio (Metal) — MLX for the fastest Apple-native throughput

How these numbers are calculated

Memory need = quantized weights + KV cache at 8,192 tokens (f16) + 0.8 GB runtime overhead.
64 GB unified memory at 273 GB/s, shared between CPU and GPU.
macOS reserves a share of unified memory for the system, so not all of it is available to a model.
Throughput is a memory-bandwidth roofline estimate, not a measurement. It is labelled "estimated" everywhere it appears.
KV cache is computed from this model's published attention configuration.
