Can Mac Studio M3 Ultra 96GB run GLM-4.5-Air?

Apple · 96 GB LPDDR5 · 819 GB/s bandwidth · Z.ai · 110.5B (active 12B) · MoE · model ctx up to 128K

Yes — the Mac Studio M3 Ultra 96GB (96 GB LPDDR5) can run GLM-4.5-Air. At Q4 with the default 8K context it needs ≈ 64.18 GB VRAM (weights 60.78 GB + KV cache 2.4 GB + 1 GB runtime overhead), which fits within 96 GB. Decode at Q4/8K: ≈ 43.4 tok/s (estimated, batch 1). FP16 needs ≈ 224.4 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	62.98 GB	Yes	43.4 est.
Q4	8K default	64.18 GB	Yes	43.4 est.
Q4	32K	71.38 GB	Yes	43.4 est.
FP16	4K	223.2 GB	No	6.3 est.
FP16	8K default	224.4 GB	No	6.2 est.
FP16	32K	231.6 GB	No	5.9 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).
