Can MacBook Pro M4 Max 128GB run DeepSeek-R1-Distill-Qwen-7B?
Apple · 128 GB LPDDR5X · 546 GB/s bandwidth ·
DeepSeek · 7.6B · model ctx up to 128K
Yes — the MacBook Pro M4 Max 128GB (128 GB LPDDR5X) can run DeepSeek-R1-Distill-Qwen-7B. At Q4 with the default 8K context it needs ≈ 6.7 GB VRAM (weights 4.18 GB + KV cache 1.52 GB + 1 GB runtime overhead), which fits within 128 GB. Decode at Q4/8K: ≈ 45.7 tok/s (estimated, batch 1). FP16 (≈ 17.72 GB) also fits, at ≈ 12.6 tok/s (estimated). Estimates come from memory-bandwidth math; rows tagged measured override estimates. Relative ranking is more reliable than absolute tok/s.

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).
