Can MacBook Pro M3 Max 128GB run NVIDIA-Nemotron-3-Ultra-550B-A55B-NVFP4?

Apple · 128 GB LPDDR5 · 400 GB/s bandwidth · NVIDIA · 550.0B (active 55.0B) · MoE · model ctx up to 256K

No — NVIDIA-Nemotron-3-Ultra-550B-A55B-NVFP4 at Q4 needs ≈ 309.0 GB even at 4K context, beyond the MacBook Pro M3 Max 128GB's 128 GB LPDDR5. It would only run with heavy CPU/disk offload. Decode at Q4/8K: ≈ 2.2 tok/s (estimated, batch 1). FP16 needs ≈ 1112.0 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	309.0 GB	No	2.3 est.
Q4	8K default	314.5 GB	No	2.2 est.
Q4	32K	347.5 GB	No	1.8 est.
FP16	4K	1106.5 GB	No	—
FP16	8K default	1112.0 GB	No	—
FP16	32K	1145.0 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).
