Can MacBook Pro M4 Max 128GB run Mistral-Small-4-119B-2603?

Apple · 128 GB LPDDR5X · 546 GB/s bandwidth · Mistral · 119.0B (active 6.5B) · MoE · model ctx up to 256K

Yes — the MacBook Pro M4 Max 128GB (128 GB LPDDR5X) can run Mistral-Small-4-119B-2603. At Q4 with the default 8K context it needs ≈ 67.75 GB VRAM (weights 65.45 GB + KV cache 1.3 GB + 1 GB runtime overhead), which fits within 128 GB. Decode at Q4/8K: ≈ 53.5 tok/s (estimated, batch 1). FP16 needs ≈ 240.3 GB — does not fit on this card. 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	67.1 GB	Yes	53.5 est.
Q4	8K default	67.75 GB	Yes	53.5 est.
Q4	32K	71.65 GB	Yes	53.5 est.
FP16	4K	239.65 GB	No	12.0 est.
FP16	8K default	240.3 GB	No	11.9 est.
FP16	32K	244.2 GB	No	11.5 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).
