Can MacBook Pro M3 Max 128GB run Qwen3-4B-Instruct-2507?

Apple · 128 GB LPDDR5 · 400 GB/s bandwidth · Alibaba · 4.0B · model ctx up to 256K

Yes — the MacBook Pro M3 Max 128GB (128 GB LPDDR5) can run Qwen3-4B-Instruct-2507. At Q4 with the default 8K context it needs ≈ 4.0 GB VRAM (weights 2.2 GB + KV cache 0.8 GB + 1 GB runtime overhead), which fits within 128 GB. Decode at Q4/8K: ≈ 63.6 tok/s (estimated, batch 1). FP16 (≈ 9.8 GB) also fits, at ≈ 17.5 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).
