Can MacBook Pro M4 Max 128GB run gemma-4-12b-it?

Apple · 128 GB LPDDR5X · 546 GB/s bandwidth · Google · 11.95B · model ctx up to 256K

Yes — the MacBook Pro M4 Max 128GB (128 GB LPDDR5X) can run gemma-4-12b-it. At Q4 with the default 8K context it needs ≈ 9.96 GB VRAM (weights 6.57 GB + KV cache 2.39 GB + 1 GB runtime overhead), which fits within 128 GB. Decode at Q4/8K: ≈ 29.1 tok/s (estimated, batch 1). FP16 (≈ 27.29 GB) also fits, at ≈ 8.0 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	8.77 GB	Yes	29.1 est.
Q4	8K default	9.96 GB	Yes	29.1 est.
Q4	32K	17.13 GB	Yes	29.1 est.
FP16	4K	26.09 GB	Yes	8.0 est.
FP16	8K default	27.29 GB	Yes	8.0 est.
FP16	32K	34.46 GB	Yes	8.0 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).
