Can Mac mini M4 32GB run Llama-3.2-3B-Instruct?

Apple · 32 GB LPDDR5X · 120 GB/s bandwidth · Meta · 3.2B · model ctx up to 128K

Yes — the Mac mini M4 32GB (32 GB LPDDR5X) can run Llama-3.2-3B-Instruct. At Q4 with the default 8K context it needs ≈ 3.4 GB VRAM (weights 1.76 GB + KV cache 0.64 GB + 1 GB runtime overhead), which fits within 32 GB. Decode at Q4/8K: ≈ 41.3 tok/s (measured, batch 1). FP16 (≈ 8.04 GB) also fits, at ≈ 6.6 tok/s (estimated). Estimates come from memory-bandwidth math; rows tagged measured override estimates. Relative ranking is more reliable than absolute tok/s. Methodology.

Fit & speed by quant and context

Quant	Context	VRAM needed	Fits?	tok/s (decode)
Q4	4K	3.08 GB	Yes	41.3 measured
Q4	8K default	3.4 GB	Yes	41.3 measured
Q4	32K	5.32 GB	Yes	41.3 measured
FP16	4K	7.72 GB	Yes	6.6 est.
FP16	8K default	8.04 GB	Yes	6.6 est.
FP16	32K	9.96 GB	Yes	6.6 est.

Fits = weights + KV(ctx) + 1 GB overhead ≤ 95% of VRAM. Measured anchors are context-agnostic; the fit verdict is recomputed per context. A missing tok/s means the model is far beyond this card (offload-only territory).
