Can MacBook Pro M3 Max 128GB run DeepSeek-V4-Flash?

Apple · 128 GB LPDDR5 · 400 GB/s bandwidth · DeepSeek · 158.1B (active 13B) · MoE · model ctx up to 1000K

Yes — the MacBook Pro M3 Max 128GB (128 GB LPDDR5) can run DeepSeek-V4-Flash. At Q4 with the default 8K context it needs ≈ 90.55 GB VRAM (weights 86.95 GB + KV cache 2.6 GB + 1 GB runtime overhead), which fits within 128 GB. Decode at Q4/8K: ≈ 19.6 tok/s (estimated, batch 1). FP16 needs ≈ 319.8 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	89.25 GB	Yes	19.6 est.
Q4	8K default	90.55 GB	Yes	19.6 est.
Q4	32K	98.36 GB	Yes	19.6 est.
FP16	4K	318.5 GB	No	2.5 est.
FP16	8K default	319.8 GB	No	2.5 est.
FP16	32K	327.6 GB	No	2.3 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).
