Can MacBook Pro M3 Max 128GB run Mistral-7B-Instruct-v0.3?
Apple · 128 GB LPDDR5 · 400 GB/s bandwidth ·
Mistral · 7.2B · model ctx up to 32K
Yes — the MacBook Pro M3 Max 128GB (128 GB LPDDR5) can run Mistral-7B-Instruct-v0.3. At Q4 with the default 8K context it needs ≈ 6.4 GB VRAM (weights 3.96 GB + KV cache 1.44 GB + 1 GB runtime overhead), which fits within 128 GB. Decode at Q4/8K: ≈ 38.0 tok/s (measured, batch 1). FP16 (≈ 16.84 GB) also fits, at ≈ 9.7 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).
