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.

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).
