Can Mac Studio M3 Ultra 96GB run Mistral-Medium-3.5-128B?

Apple · 96 GB LPDDR5 · 819 GB/s bandwidth · Mistral · 128.0B · model ctx up to 256K

Partly — Mistral-Medium-3.5-128B at Q4 fits the Mac Studio M3 Ultra 96GB (96 GB LPDDR5) at 4K context (≈ 84.2 GB) but not at the default 8K (≈ 97.0 GB needed). Use a shorter context or partial offload. Decode at Q4/8K: ≈ 11.4 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	4.1 est.
Q4	8K default	97.0 GB	No	11.4 est.
Q4	32K	173.8 GB	No	3.5 est.
FP16	4K	269.8 GB	No	0.4 est.
FP16	8K default	282.6 GB	No	0.4 est.
FP16	32K	359.4 GB	No	0.2 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).
