Can Mac Studio M2 Ultra 192GB run Hy3?

Apple · 192 GB LPDDR5 · 800 GB/s bandwidth · Tencent · 295.0B (active 21.0B) · MoE · model ctx up to 256K

Yes — the Mac Studio M2 Ultra 192GB (192 GB LPDDR5) can run Hy3. At Q4 with the default 8K context it needs ≈ 167.45 GB VRAM (weights 162.25 GB + KV cache 4.2 GB + 1 GB runtime overhead), which fits within 192 GB. Decode at Q4/8K: ≈ 24.2 tok/s (estimated, batch 1). FP16 needs ≈ 595.2 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	165.35 GB	Yes	24.2 est.
Q4	8K default	167.45 GB	Yes	24.2 est.
Q4	32K	180.05 GB	Yes	24.2 est.
FP16	4K	593.1 GB	No	2.0 est.
FP16	8K default	595.2 GB	No	2.0 est.
FP16	32K	607.8 GB	No	1.9 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).
