Can I Run Mistral NeMo 12B on Apple M3 Pro?
Written by Jakub Rusinowski · Last updated September 29, 2026
Yes. Mistral NeMo 12B needs 9.4 GB at 8K context (7.2 GB weights + 2.2 GB KV cache/overhead) at Q4_K_M and the Apple M3 Pro has 27 GB usable, leaving about 17.6 GB of headroom, at roughly 10 tok/s (estimated) with room for up to 64K of context.

Mistral NeMo 12B on the Apple M3 Pro: VRAM by quantization
| Quant | VRAM needed | Fits 36 GB? | Max context | Whole PC |
|---|---|---|---|---|
| F16 | 26.1 GB | ✓ Yes | 8K | — |
| Q8_0 | 14.9 GB | ✓ Yes | 64K | Build for this |
| Q6_K | 12 GB | ✓ Yes | 64K | — |
| Q5_K_M | 10.6 GB | ✓ Yes | 64K | — |
| Q4_K_M | 9.4 GB | ✓ Yes | 64K | Build for this |
| Q3_K_M | 7.3 GB | ✓ Yes | 64K | — |
| Q2_K | 6.1 GB | ✓ Yes | 128K | — |
Assumes an 8K-token context with an f16 KV cache. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 36 GB of unified memory. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.
Context costs VRAM too. At Q4_K_M on the Apple M3 Pro: 8K 9.4 GB · 32K 13.4 GB · 128K 29.5 GB ✗. Past 128K it no longer fits 36 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
What to do next
Nothing to change — run it at Q4_K_M. If you want more capability, check whether the next size up also fits.
