Can MacBook Pro M4 Max 128GB run Devstral-Small-2-24B-Instruct-2512?
Apple · 128 GB LPDDR5X · 546 GB/s bandwidth ·
Mistral · 24.0B · model ctx up to 256K
Yes — the MacBook Pro M4 Max 128GB (128 GB LPDDR5X) can run Devstral-Small-2-24B-Instruct-2512. At Q4 with the default 8K context it needs ≈ 19.0 GB VRAM (weights 13.2 GB + KV cache 4.8 GB + 1 GB runtime overhead), which fits within 128 GB. Decode at Q4/8K: ≈ 14.5 tok/s (estimated, batch 1). FP16 (≈ 53.8 GB) also fits, at ≈ 4.0 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).
