Can Mac Studio M2 Ultra 192GB run Mistral-Medium-3.5-128B?

Apple · 192 GB LPDDR5 · 800 GB/s bandwidth · Mistral · 128.0B · model ctx up to 256K

Yes — the Mac Studio M2 Ultra 192GB (192 GB LPDDR5) can run Mistral-Medium-3.5-128B. At Q4 with the default 8K context it needs ≈ 97.0 GB VRAM (weights 70.4 GB + KV cache 25.6 GB + 1 GB runtime overhead), which fits within 192 GB. Decode at Q4/8K: ≈ 4.0 tok/s (estimated, batch 1). FP16 needs ≈ 282.6 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	84.2 GB	Yes	4.0 est.
Q4	8K default	97.0 GB	Yes	4.0 est.
Q4	32K	173.8 GB	Yes	4.0 est.
FP16	4K	269.8 GB	No	1.6 est.
FP16	8K default	282.6 GB	No	1.4 est.
FP16	32K	359.4 GB	No	0.9 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).
