Can MacBook Pro M3 Max 128GB run DeepSeek-R1-Distill-Qwen-32B?

Apple · 128 GB LPDDR5 · 400 GB/s bandwidth · DeepSeek · 32.8B · model ctx up to 128K

Yes — the MacBook Pro M3 Max 128GB (128 GB LPDDR5) can run DeepSeek-R1-Distill-Qwen-32B. At Q4 with the default 8K context it needs ≈ 25.6 GB VRAM (weights 18.04 GB + KV cache 6.56 GB + 1 GB runtime overhead), which fits within 128 GB. Decode at Q4/8K: ≈ 7.8 tok/s (estimated, batch 1). FP16 (≈ 73.16 GB) also fits, at ≈ 2.1 tok/s (estimated). Estimates come from memory-bandwidth math; rows tagged measured override estimates. Relative ranking is more reliable than absolute tok/s. Methodology.

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).
