Can Mac Studio M2 Ultra 192GB run DeepSeek-V4-Flash?

Apple · 192 GB LPDDR5 · 800 GB/s bandwidth · DeepSeek · 158.1B (active 13B) · MoE · model ctx up to 1000K

Yes — the Mac Studio M2 Ultra 192GB (192 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 192 GB. Decode at Q4/8K: ≈ 39.2 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	39.2 est.
Q4	8K default	90.55 GB	Yes	39.2 est.
Q4	32K	98.36 GB	Yes	39.2 est.
FP16	4K	318.5 GB	No	11.2 est.
FP16	8K default	319.8 GB	No	11.1 est.
FP16	32K	327.6 GB	No	10.6 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).
