Can Mac Studio M2 Ultra 192GB run Kimi-K2-Instruct-0905?

Apple · 192 GB LPDDR5 · 800 GB/s bandwidth · Moonshot · 1026.5B (active 32B) · MoE · model ctx up to 256K

No — Kimi-K2-Instruct-0905 at Q4 needs ≈ 568.78 GB even at 4K context, beyond the Mac Studio M2 Ultra 192GB's 192 GB LPDDR5. It would only run with heavy CPU/disk offload. Decode at Q4/8K: ≈ 5.1 tok/s (estimated, batch 1). FP16 needs ≈ 2060.4 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	568.78 GB	No	5.2 est.
Q4	8K default	571.98 GB	No	5.1 est.
Q4	32K	591.18 GB	No	4.8 est.
FP16	4K	2057.2 GB	No	—
FP16	8K default	2060.4 GB	No	—
FP16	32K	2079.6 GB	No	—

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).
